Any help appreciated >Thanks, >- - Tom The connectors are manufactured by AMP and designated "junior timer" or "junior power timer". The two are inter-changeable, but the power timer version is better;the terminal design is a lot more robust. Note though that the terminals are not interchangeable across ranges - only use "power timer" terminals in "power timer" housings and vice versa. Sizes covered include 2,3,4,5,7 way and also larger 15,25 and 35way which are used on the ECU (25 for Ljet) Part numbers for power timer housings: 2way - 282189-1 3way - 282191-1 4way - 282192-1 5way - 282193-1 terminals available with a variety of finishes and wire size compatibility. Check www.AMP.com for more details and part numbers for other examples. This doesn't answer the original question though! - where from?? In the UK I know they are available from Fuelparts UK. They have a website, but I don't have the details to hand - something like www.fuel-parts.co.uk ?? I think Delphi Packard do an equivalent range - at least for some examples (2way injector connector for sure).

Watch the change in the signal line. Depending on the type of MAP, the starting reading will vary depending on your altitude (barometric pressure). Most start out somewhere around 4.6-4.9v w/no vacuum. A very crude bench test for an o2 sensor is to mount it in a vise and heat it with a propane torch. As it warms up, it will begin to produce a voltage. Not very accurate but it will indicate if it is completely dead.

This supposes that you are running speed/density from a fuel table. The TPS reading is taken from the A/D and placed on a stack. This is done say 10 times every say 10 msec until a "history" of TPS is available. As soon as a new reading is placed on the stack you do a 1st minus last to give delta TPS. If the number is equal to the max. possible delta you inject 100% of the Variable AccEnr ms adding it to the Full Load fuel ms for that RPM. If its say 40 counts you add 40% of the AccEnr to the next injection. Some ECU's calculate the proportion lost to some cylinders due to their position in the cycle and add that to the next injection after that. This is due to the fact that when ever you inject it is only half the fuel that is supplied per rev of the engine and some cylinders will only get 50% of the enrichment. This is also true if the result is negative you can subtract the inverse and avoid the over rich "puff" that you get when the throttle is closed suddenly As you can see we are assuming that as the throttle is translating rapidly the MAP sensor will be reading close to atms very "SOON" thus we are using throttle translation as a predictor of ultimate load. Now of course the algorithm for the decay of the AccEnr is something that you didn't ask about but suffice to say you could make it a variable based on the rate of change of RPM and the starting RPM and the current load. There is quite a difference between "stabbing "the throttle to change down a gear and flooring your Acc in gear.

Have a look at frequency to voltage converters. Don't know who makes them, but it shouldn't take long to find a datasheet. I'm not sure how accurate they can be, but you should be able to hook one up with a multimeter as a display, or use the movement in the tach if it is accurate enough. A friend of mine put such a circuit into his misbehaving period tach. Looks completely original from the outside, but reads far more accuratly. Also, someone else was wondering how to connect a 6 cyclinder tach to a 4 cyclinder engine (or the reverse). You could use a freq->volt and then a voltage to frequency (voltage controlled oscilator??) with an aproprate divider between them. Just a thought, no idea if it is feasable.. -- Tom Parker - parkert@ihug.co.nz - http://www.geocities.com/MotorCity/Track/8381/ From diy_efi-owner Tue Nov 2 08:11:29 1999 Return-Path: Received: (from root@localhost) by esl.eng.ohio-state.edu (8.9.3/8.9.3) id IAA22469 for diy_efi-outgoing; Tue, 2 Nov 1999 08:11:29 -0500 Received: from smtp10.atl.mindspring.net (smtp10.atl.mindspring.net [207.69.200.246]) by esl.eng.ohio-state.edu (8.9.3/8.9.3) with ESMTP id IAA22466 for ; Tue, 2 Nov 1999 08:11:28 -0500 Received: from lizard (user-2iveajc.dialup.mindspring.com [165.247.42.108]) by smtp10.atl.mindspring.net (8.8.5/8.8.5) with SMTP id IAA10230 for ; Tue, 2 Nov 1999 08:11:26 -0500 (EST) Message-Id: <199911021311.IAA10230@smtp10.atl.mindspring.net> Comments: Authenticated sender is From: "Alex C.

Hiorns" Subject: Tach's & injector timing Sender: owner-diy_efi@esl.eng.ohio-state.edu Precedence: bulk Reply-To: diy_efi@efi332.eng.ohio-state.edu Hi, all Just got on the list. Nice to see what's going on. I design electronics, so apologies if I seem to rely on them too much ... A simple way of changing 6 or 8 pulse systems into 4 pulse systems is to use a phase locked loop with a counter ("divider") to set the ratios you want. This is particularly easy with cheap CMOS 4000 series chips which can run off 5-18v (good for autos, but maybe not trucks). Try the 4046A for the PLL (all in one chip) and a dual 4 bit counter to set the ratios (one in the feedback path and one on the input). I guess an optional input divider of 2 or 4, and feedback divider of 2 or 3, will cover 4, 6 & 8 cylinder engines, but it's pretty easy to choose ratios for more cylinders. The problem you run into is that you have to make a compromise between how quickly it'll respond, and how steady the final readout is, and this brings us neatly to designing a high accuracy digital tach for a dyno shaft. To get high accuracy on the dyno shaft, you want a lot of pulses per revolution so you can avoid too much smoothing which forces your readout to take ages to settle. This just means having many contacts/magnets/marks on the shaft for your electrical/hall-effect/optical reader. I've had great success canibalising the wheel and slotted UV opto-switch from inside an old (dead) computer mouse (although it took me ages to start with to get rid of 60Hz clocking ... had to build a box round it so the flourescent lights didn't interfere ... I guess sunlight may cause missed pulses too). You can chuck the output through a F-V converter, but a neat, flexible solution is to use a PIC microcontroller (they're amazingly cheap too). Use the event counter to time periods of the system clock and then take the reciprocal to get the frequency (algorithm in the PIC handbook) which needs scaling depending on your pickup system. I like this solution cause I can drive a digital display using the same chip ... no need to lock up my voltmeter which I invariably want for something else! The same system can also be used with a different program for dwell metering, although I noticed more readout 'wobble' with this. Perhaps if you're really concerned you could put some filtering into the program to get it down to the last Hz or degree. Hope these few thoughts help. While I'm here could I ask how to work out when injectors should be fired? When the inlet port opens seems too early; mid 'inrush' would make sense to me for best mixing (but it's rpm dependant: I'm using long inlet runners to boost lower rpm torque) ... and is there a recognised best way of getting past the 'stumble' as I changeover from sequential to batch firing? Any views appreciated.

As for heads, the good (W-2) 340 heads from the late '60's are just about unobtanium here. Other than a set of those, you are really better off to go with aftermarket heads, which are easily and economically available here--don't know your situation in that regard in Oz, though. There are definitely factory injection set-ups for the 360 available over here, at LEAST TBI type stuff. BUT--I rather doubt that any of them are a good match for any of the decent flowing heads. A call or e-mail to "Mopar Performance" might be of great worth to you in sorting out the details as to what is out there in this regard and what works well. If you are not after quite the level of performance I am implying with these leads, there is an outfit over here called Clifford Performance who make all sorts of performance goodies for Detroit's in line engines, including the 225 slant six. Their stuff could easily wake up your existing 225 six to where it runs as well as a normal cooking variety 318 or 340!! This might be a far more economical and less labor intensive approach if that is all the more power you are after! Headers, a cam, a bit more compression, a bit of head work, and a four-barrel intake with perhaps a Holley four-barrel digital Pro-Jection could make for a 225-6 that would get your attention pretty effectively!

Throttle body on standard and port injection on magnum engines. The magnum engine is the hot set-up but the heads are different from older engines. The Mopar performance division sells the magnum engine as a crate motor. I am considering building a twin turbo, efi 66 barracuda using a 360 magnum truck engine. The engine assembly will bolt into older cars with no problem. You should be able to locate all the components at a salvage yard and have them shipped. -----Original Message----- From: DIY_EFI-Digest-Owner@efi332.eng.ohio-state.edu [mailto:DIY_EFI-Digest-Owner@efi332.eng.ohio-state.edu] Sent: Wednesday, November 03, 1999 4:00 AM To: DIY_EFI-Digest@efi332.eng.ohio-state.edu Subject: DIY_EFI Digest V4 #619 DIY_EFI Digest Wednesday, November 3 1999 Volume 04 : Number 619 In this issue: Re: Small block Chrysler V8's Re: DIY_EFI Digest V4 #617 Re: Small block Chrysler V8's Tach's & injector timing RE: Dyno tach generator See the end of the digest for information on subscribing to the DIY_EFI or DIY_EFI-Digest mailing lists. ---------------------------------------------------------------------- Date: Wed, 3 Nov 1999 10:40:45 +1100 From: "Daniel Phillips" Subject: Re: Small block Chrysler V8's This is a multi-part message in MIME format. - ------=_NextPart_000_000B_01BF25E7.E23EC1E0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable Gidday All, I am considering building myself a street rod version of a 1962 Chrysler = Valiant R or S series.

After doing some reading, I have not found any after = market=20 EFI kits for this kind of motor here in Australia. Unfortunately we = stopped=20 building Chryslers here in the late 1980's.

Nice to see what's going on. I design electronics, so apologies if I seem to rely on them too much ... A simple way of changing 6 or 8 pulse systems into 4 pulse systems is to use a phase locked loop with a counter ("divider") to set the ratios you want. This is particularly easy with cheap CMOS 4000 series chips which can run off 5-18v (good for autos, but maybe not trucks). Try the 4046A for the PLL (all in one chip) and a dual 4 bit counter to set the ratios (one in the feedback path and one on the input). I guess an optional input divider of 2 or 4, and feedback divider of 2 or 3, will cover 4, 6 & 8 cylinder engines, but it's pretty easy to choose ratios for more cylinders. The problem you run into is that you have to make a compromise between how quickly it'll respond, and how steady the final readout is, and this brings us neatly to designing a high accuracy digital tach for a dyno shaft. To get high accuracy on the dyno shaft, you want a lot of pulses per revolution so you can avoid too much smoothing which forces your readout to take ages to settle. This just means having many contacts/magnets/marks on the shaft for your electrical/hall-effect/optical reader. I've had great success canibalising the wheel and slotted UV opto-switch from inside an old (dead) computer mouse (although it took me ages to start with to get rid of 60Hz clocking ... had to build a box round it so the flourescent lights didn't interfere ... I guess sunlight may cause missed pulses too). You can chuck the output through a F-V converter, but a neat, flexible solution is to use a PIC microcontroller (they're amazingly cheap too). Use the event counter to time periods of the system clock and then take the reciprocal to get the frequency (algorithm in the PIC handbook) which needs scaling depending on your pickup system. I like this solution cause I can drive a digital display using the same chip ... no need to lock up my voltmeter which I invariably want for something else! The same system can also be used with a different program for dwell metering, although I noticed more readout 'wobble' with this. Perhaps if you're really concerned you could put some filtering into the program to get it down to the last Hz or degree. Hope these few thoughts help. While I'm here could I ask how to work out when injectors should be fired? When the inlet port opens seems too early; mid 'inrush' would make sense to me for best mixing (but it's rpm dependant: I'm using long inlet runners to boost lower rpm torque) ... and is there a recognised best way of getting past the 'stumble' as I changeover from sequential to batch firing? Any views appreciated. Rod ------------------------------ Date: Wed, 3 Nov 1999 09:06:38 -0000 From: "Rich M" Subject: RE: Dyno tach generator >Have a look at frequency to voltage converters.

LM2907 or LM2917 from National Semiconductors.
Linearity typically 0.3%. You get to trade off = output ripple variation
against speed of response/settling time.

I've used them for both retrofit to moving coil tach = and for digital
display, both work fine.

Also, please trim your replies? A 3 line reply doesn't need all of yesterdays digest in HTML and text with it.

The car has 62K miles and is in excellent condition. It will start after about 6-8 seconds of cranking, but will then just rush once or twice and quit if throttle not opened. It will not idle. It runs great above about 2000 rpm all the way to the redline without any power loss. While holding the rpm at between 1500-2000 (rough in this range), the check engine light flashed a 1223 code (lambda internal control). Over the past few months, I've had intermittent problems with low/rough idle (speed about 600 rpm) and stalling when taking off. Other times there were no problems at all. I'm new to the auto repair game, so please assume that I don't know jack. Here's what I've checked/done so far: Air-flow meter resistances are OK with smooth flapper operation and resistance changes. I tried a spare AFM I have--no real change. Throttle switch is OK. Idle speed actuator gets battery voltage with ignition "on." Spark plugs OK. Tightened up all air intake connections. Replaced fuel filter. The battery is old and probably needs replaced--sometimes cranking is slow. I'm replacing it today. Can this cause a problem with idle? I haven't checked fuel pressure yet since I can't find a fuel pressure guage that is compatible with the car (only domestic Schrader valve types around here). Any tips on where I can buy one? My shop manual says to "supply idle speed actuator with 12V directly for awhile and check for proper functioning." Basically, I just plugged in the connector and turned the ignition to "on" with the bypass hose disconnected. I couldn't see anything happening inside the device. I don't really know how this thing is supposed to function, though. Can anyone enlighten me? Thanks in advance.

I have some questions for some EFI gurus. I was wondering if anybody is familiar with the Texas Instruments or Hewlit Packard line of graphing calculators. They are prety powerful little beasts. I know that the TI uses an OS very similar to BASIC and that it also uses an ASEMBLY language. They might be ideal because they are built for calculating complicated stuff. I was thinking that a TI calc (maybe a ti 92) might be perfect for a simple fuel injection system. The TI calcs are very popular and a lot of people write stuff for them, they have many followers. I don't know if they have enough I/O for the multitude of sensors that even a simple EFI system would require. Maybe someone can tell me?

I was able to get the car to idle by changing the position of the flapper reference along the potentiometer, effectively increasing the resistance for any given air flow. This was a bit of a rough idle with near-stalling upon initial throttle opening. I noticed that at this "pseudo-idle" the flapper was completely closed. Manually opening the flapper just a bit by moving the potentiometer arm smoothed out the idle and improved the throttle response. This was still the case after putting the flapper reference on the potentiometer back to original setting. Squeezing off the air bypass hose to the idle speed actuator had no effect on the "pseudo-idle." >From this, I assume that the idle speed actuator is not letting air in (if it were, the flapper should be a little open at idle, shouldn't it?). Thus, manually opening the flapper allowed in a little air, effectively "substituting" for the idle speed actuator. I took off the ISA and examined it. The valve seemed to open and close without difficulty. I went ahead and cleaned it with throttle body cleaner to be sure (thanks Dylan). I noticed that in the fully closed position, there was about a 3mm gap present, i.e., the valve is over-rotated past the closed position. I couldn't adjust this because the adjustment screw was frozen. I suspect that because of this maladjustment the valve doesn't completely open like it's supposed to (i.e., it's about 3mm less open than it should be at any given time). I reconnected the ISA and cranked the engine while watching it. It seems to function. I still think, however, that it isn't letting air through because of the above reasons. I'm planning to replace it. If anyone thinks this is a bad idea, please let me know. Any other input is greatly appreciated.

Any other input is greatly appreciated. Before you replace it, check for splits or leaks in the air tubing/trunking on the engine side of the airflow meter and ISA. I have come across a similar effect of rough idle on a LE2 sytem for just this reason: at idle the leak represents a significant bypass round the airflow meter, so allowing the flap to close and cut off the fuel creating a very weak mixture. As the throttle is opened, the leak becomes less and less significant and engine operation appears to return to normal. This is obviously only one possibility, but it is very real; the split doesn't need to be that big - check carefully round any concertina sections of air trunking where splits may not at first be obvious. hope this might help.

The problem is not with the technology, but with lazy users. If people can't expend the effort to edit a reply back to just the essentials, and make sure they have HTML turned off, and perhaps check their spelling, etc. then the end result will be that fewer people will read, and respond, to DIY. Flip side is that if the effort involved in deciphering or responding is too great, people will not read nor respond anyway. Perhaps that's already happened? PG.

I've tried running spell check and for all the fooling around using auto/mechanical abbrevations I have other things to do. Also, this is a multinational list, and some items lose it in translation. IMHO, BFD. If the writer pretty well puts a point across, if I know the answer, I respond. The list goes thru cycles busy at times, and slower at others.

Non-digest mode works just fine. It's just that it's too great a load for our sponsor's server. IF we can find an email relay for the outgoing diy_efi mail, then we can go back to regular mode.

I am buying a used Accel DFI system that was hooked up to a chev V8 . The Nissan motor came with a factory crank angle sensor, it has two types of teeth main set of teeth every 20 degrees and 3 big ones at 120 degrees . There is an inductive pickup mounted on this sensor with 3 magnets .. 1) Can this crank trigger be used on the Accel DFI? A guy runs same system but with a normal 280zx distributor for sensing igntion timing 2) Is there some sort of inductive pickup used in the distributor ? Someone else is trying to use Accel DFI with same motor only he is trying to hook up GM coilpacks to fire the plugs . 3) What is involved in making DFI fire coilpacks, is there a wiring diagram available for this . I am buying a Calmap software package will this include a pinout diagram out the Accel ECU nothing is marked on the used system I bought . If you have any suggestion or know any webpages that would help me get started it would be appreciated .

Use a manifold lid meant to mount a single dominator. You can get 4 bbl "air doors" designed to mount on a Dominator bolt pattern manifold that will flow 2000 cfm @ 1.5" Hg pressure drop--which oughtta be quite plenty! These " air door" units can be gotten complete with a TPS and an IAC motor, all mounted, if you want. Weld injector bungs onto each cross ram runner at the appropriate spot. You can buy ready made weld or screw in bungs from MSD Fuel Systems (same folks as the ignitions), located in El Paso). One of the cross rams with a huge plenum oughtta run pretty impressively, even on the street, with DRY flow in the plenum!! I would have to look at one of these manifolds pretty closely, if might take a bit of creative fabricating to get the injector rails up outside of the plenum lid, but mebbe not. Or--mebbe put the injectors and rails in the valley?? :-) Greg From diy_efi-owner Mon Nov 8 20:20:25 1999 Return-Path: Received: (from root@localhost) by esl.eng.ohio-state.edu (8.9.3/8.9.3) id UAA31687 for diy_efi-outgoing; Mon, 8 Nov 1999 20:20:25 -0500 Received: from Prime-FE2.lvcablemodem.com (pop3.lvcablemodem.com [24.234.0.11]) by esl.eng.ohio-state.edu (8.9.3/8.9.3) with ESMTP id UAA31684 for ; Mon, 8 Nov 1999 20:20:24 -0500 Received: from pop3.lvcablemodem.com - 24.234.0.11 by lvcablemodem.com with Microsoft SMTPSVC; Mon, 8 Nov 1999 17:27:47 -0800 Received: from itsmike (dhcp002.62.lvcm.com [24.234.62.2]) by pop3.lvcablemodem.com with SMTP (MailShield v1.5); Mon, 08 Nov 1999 17:27:47 -0800 From: "Mike" To: Subject: RE: DIY_EFI Digest V4 #631 Date: Mon, 8 Nov 1999 17:19:34 -0800 Message-ID: MIME-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 7bit X-Priority: 3 (Normal) X-MSMail-Priority: Normal X-Mailer: Microsoft Outlook IMO, Build 9.0.2416 (9.0.2910.0) X-MimeOLE: Produced By Microsoft MimeOLE V5.00.2314.1300 In-Reply-To: <199911082000.PAA25437@esl.eng.ohio-state.edu> Importance: Normal Sender: owner-diy_efi@esl.eng.ohio-state.edu Precedence: bulk Reply-To: diy_efi@efi332.eng.ohio-state.edu Why not run a plenum that bolts to the 3 2's and run one big tb?

The IAC is nothing more than a servo, so one can fabricate a 4-wire servo to pull the throttle cable in or not, that's not that difficult.

I have an 82 Nissan 280zx L28ET and on a cold day it can run 14lbs boost and can run 12lbs boost at any time without any problem. I embarrassed, didn't' beat, but embarrassed a new Corvette C5 (I would have been embarrassed to have an old 280 pace my $60,000 car). The injectors are stock. I have made other external modification (if you are interested drop me a line) If you want to improve the performance of the efi, contact Wolf, they make boards for your car that greatly improve performance. I don't use one myself as the cost is about $500. The point I am making is that you will probably spend a lot of money and time that would not even reach the excellence of the tuned stock system. >Date: Mon, 8 Nov 1999 16:24:44 -0600 >From: "Clint S." >Subject: Accel DFI hookup > >I own an 81 Nissan 280zx L28ET turbo motor inline 6 . >I am buying a used Accel DFI system that was hooked up to a chev V8 .

I do have the dyno next to me for the same engine when I compared a Performer RPM Vs a Bowtie single plane (similar to a Victor Jr.). The dyno I ran on would only pull down to 3000 to 3500 RPM so all runs were begun at 3500 and ran through 6500. The minimum gains with the fuel injection were in the 30 to 35 lb/ft range even at 3500. There was no loss in power compared to the carb at any piont in the pull. I know the increase in power has carried down in the powerband because after the conversion the car no longer hooks up from a standing start. I run about 2300 stall with a built 700R4 and it will light it up, in smoke, to 6500 right now. It did not have those beans before. I shift at 6500 to 6850 and I think the drop is to about 4000 in second, I just have never paid attention to the tach after the shift. I will check it out this weekend and E-mail you directly. Part of the success I have had is spending the time (2-3 hours at a time) driving and tuning the fuel curves at various loads and rpm points. This has made a big difference. I probably have 40 to 50 hours in tuning time dialing things in. Your thoughts with the single plane Vs dual plane with carb are accurate based on the dyno runs I made with the same engine comparing a Performer RPM to a Bowtie single plane. When I first built this engine I ran the Performer and a carb. In essence they were both about the same on the bottom end (5 to 10 lb/ft diff. max at some RPM points) but I gained on the top end (above 5000) 10 to 20 HP. One thing which put the Bowtie at a disadvantage was the dual plane was port matched and the bowtie was not. When we were putting on the Bowtie I could see the ports were not matched very well. At that time, if I had not spent the money to port the dual plane, I would have gone with the Bowtie/carb combo. I know I would have gained back what I lost on the bottom and gained more top end if everything was ported. On another note I am just beginning to build a 440 small block and am anticipating going with the Speed Pro system. Anybody have any thoughts or experience with this system? To me it seems to be the most up to date and well thought out system out there especially with the wide band O2 capability.

I just want to confirm: the AFM flapper IS supposed to be slightly open at idle, right? Now for some more novice troubleshooting: I disconnected the idle air bypass hose from the intake ducting and left this end open to the air. I plugged the hole left in the intake ducting. As I expected, the car would start and "pseudo-idle" (with flapper reference advanced on the AFM potentiometer to increase resistance, as before). However, when I blocked the open end of the idle air bypass tubing, the car stalled. Thus the idle speed actuator must be working. (previously, I had just clamped the tubing to test this, but I must not have completely blocked the flow) I disassembled all of the upper intake ducting, and found no holes or potential leak spots between the AFM and ISA or throttle assembly. It seems to me that anything causing any leak into the plenum chamber would effectively decrease the vacuum in this chamber and decrease the amount of air flowing through the idle speed actuator (and thus, through the AFM). So,I also checked everything that connects to the plenum chamber (oil vapor hose, fuel vapor hose and solenoid, fuel pressure regulator tubing) and found no leaks. I can hear a distinct hissing sound coming from around the bottom of the plenum chamber where it intersects with the engine or just forward of this area. This hissing intensifies just after the throttle is blipped and before the engine responds. It continues with decreased intensity as the rpm's rise. To me, this sounds like an air leak, but I've never heard one. Could this sound be coming from something else, such as circulating coolant? When this idle problem first started (weeks ago), I checked the rubber sleeves and clamps that seal the joints between the plenum outflows and intake runners of the cylinders. I noticed that all of them were slightly loose and had worked their way toward the engine side. I could even see the joint past the edge of one of them. At that time, I loosened all of them, moved them back toward the plenum side, and retightened the clamps (really tight). I guess I could've damaged them in the process since they were very difficult to get to. I can't see any obvious damage, but I can't see the underside of them. What is the best way to localize the leak (specifics please!)-- I've read about using a propane torch, but I'm a bit leery of this. Also, what could be other potential sources for the leak if there is one?

To me, this sounds like an air leak, but I've never heard one. >Could this sound be coming from something else, such as circulating coolant? When this sort of problem is a possiblity with a carb, I've always been told to spray something like wd40 around possible leak points. The extra fuel richens the (rather lean) mixture and the revs rise. If I understand efi correctly, when it is running in closed loop at idle, it should be compensating for the extra air by putting in more fuel in. So adding even more fuel (and wd40 doesn't run your engine so well) shouldn't make much of a difference. Worth a try, if spraying has any effect then there sounds like a problem to me. -- Tom Parker - parkert@ihug.co.nz - http://www.geocities.com/MotorCity/Track/8381/ From diy_efi-owner Wed Nov 10 10:29:22 1999 Return-Path: Received: (from root@localhost) by esl.eng.ohio-state.edu (8.9.3/8.9.3) id KAA04180 for diy_efi-outgoing; Wed, 10 Nov 1999 10:29:22 -0500 Received: from swan.prod.itd.earthlink.net (swan.prod.itd.earthlink.net [207.217.120.123]) by esl.eng.ohio-state.edu (8.9.3/8.9.3) with ESMTP id KAA04173 for ; Wed, 10 Nov 1999 10:29:20 -0500 Received: from srgnt (1Cust68.tnt22.sfo3.da.uu.net [63.27.230.68]) by swan.prod.itd.earthlink.net (8.9.3/8.9.3) with SMTP id HAA06057; Wed, 10 Nov 1999 07:29:16 -0800 (PST) Message-ID: <38298EC3.85C@earthlink.net> Date: Wed, 10 Nov 1999 07:26:59 -0800 From: Jason Leone X-Mailer: Mozilla 3.0C-NSCP (Win95; U) MIME-Version: 1.0 To: diy_efi@efi332.eng.ohio-state.edu CC: Tom Parker Subject: Re: Electromotive CPS Pinout References: <199911101000.FAA30279@esl.eng.ohio-state.edu> Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Sender: owner-diy_efi@esl.eng.ohio-state.edu Precedence: bulk Reply-To: diy_efi@efi332.eng.ohio-state.edu DIY_EFI Digest wrote: > > Date: 10 Nov 99 18:00:33 +1200 > From: "Tom Parker" > Subject: Electromotive CPS Pinout > > Hi, > > I've just bought an electromotive crank trigger wheel and sensor.

The only issues would be: 1) aquiring a PC for the list, 2) setting it up, 3) routine maintenance. 1 and 2 probably aren't problems, I'm sure list members could come up with cash or a machine. The only problem with #3 is that there's not a list member located at the machine to take care of problems. Their co-location deal includes some sort of timeout reboot, such that if the machine locks up it'll get rebooted after a period of time. Hopefully other problems can be handled remotely as they are now. They're right on a couple of the big pipes so throughput shouldn't be a problem (diy_efi can go back to non-digest!).

So, the Red should be the signal wire. Um... so you're saying that there is a sensor ground, a shield and a signal wire? What sort of sensor is this? Is it a hall effect sensor (which definatly require a power supply) or something I am not familiar with, like a reluctor? I've just hooked it up to my osciliscope. Between the black wire and the red wire I get quite a good signal (of the order of 1 volt p-p) by waving bits of metal in front of the sensor. There doesn't appear to be a connection between the braided sheild and anything else. Can someone explain how this sensor works? Is it just a coil of wire with a magnet through it, and when metal comes near it disturbs the field changing the flux through the coil and therefore inducing a voltage? Is this the reluctor sensor that I've heard about? -- Tom Parker - parkert@ihug.co.nz - http://www.geocities.com/MotorCity/Track/8381/ From diy_efi-owner Wed Nov 10 17:39:10 1999 Return-Path: Received: (from root@localhost) by esl.eng.ohio-state.edu (8.9.3/8.9.3) id RAA19296 for diy_efi-outgoing; Wed, 10 Nov 1999 17:39:10 -0500 Received: from mail.airmail.net (mail.airmail.net [206.66.12.40]) by esl.eng.ohio-state.edu (8.9.3/8.9.3) with SMTP id RAA19293 for ; Wed, 10 Nov 1999 17:39:08 -0500 Received: from todd-s from [208.10.224.76] by mail.airmail.net (/\##/\ Smail3.1.30.16 #30.416) with smtp for sender: id ; Wed, 10 Nov 99 16:39:07 -0600 (CST) Message-ID: <382A11DF.1E5D@airmail.net> Date: Wed, 10 Nov 1999 16:46:23 -0800 From: "Todd....!!"

OR #2: Get a sponsor who can stick his ads at the top of each e-mail! I think a teenee tiny ad at the top of each e-mail wouldn't hurt anyone... And if it comes down to it... it would be an almost unnoticeable change to the list.... You YOURSELF could even offer sponsorship (i.e. sell advertising) to various auto parts dealers and like suppliers for a tiny contribution in return! Whatchatink? Just for example, my Dad has a body shop, brother in law owns and runs the auto parts store in his town, cousin in law works at a big car dealer right outside of WACO, TX, etc..... I'm SURE others on this list have the same kinda of friends, family, acquantances and the like.... that may want to sponsor somethin such as this list! Just a couple a thoughts! Got a 10% raise today without even askin for it! COOL? Not much but at least it's SOMETHIN! Keep up the GREAT work all! LATER!

The basic computer has all the switches in the software, you can add modules depending on what you want to do. Software switchable, plug in your choice of wide band, 1-wire or heated o2 sensor. It will run in closed loop just like the Speed-Pro at WOT. Up to 16 injectors, staged. Distributorless ign. Up to 8 cyls. Plug in your injector size, and hook up the nitrous, plug in the nozzle size, pressure and bottle temp and the ecm adjusts the pw to work with up to 3 stages of nitrous. Normal, and 1-3 bar map sensor, set the software. More I can't remember! It was Windoz, 95,98 & NT friendly!

My server is a dial-up server with a dedicated IP address, utilizing two 56K modems in parallel, using somethign called multilink, which in a nutshell, means the two modems appear on the internet as one modem, sharing an IP address, combining the bandwith for a pitiful 112K max baud. I currently use NT for my firewall, my exchange server, my web and ftp, and my linux majordomo box quietly hides behind the exchange server, using exchange as a relay (from the inside only), so it doesn't need DNS information. It assumes the exchange box can figure it out. Anyway, I did some preliminary testing of performance this evening, and found that Linux, with its magical ability to have the OS/programs talk directly to the hardware, can offer 30% gain in ability to use bandwith over NT 4.0 with any service pack release. Exact hardware. So if Orin & Steve run out of options, or cannot find a service that will host the list(s) for a reasonable amount of money, maybe we can do it here at Xephic. Hardware is clearly not the problem. Even though most of the boxes are not new spiffy pentiums 400's (they are actually much older clunkers), I do have tons of disk space available, have a tape library system for proper backups, several CDROM towers, UPS power, and "data center" like floor mounted racks mounted in an airconditioned basement that could be used as necessary. I can even configure majordomo, however what kills me is the ipchains/ipfwadm firewalling, sendmail, dns, and other configurations, which would be necessary for "My" stuff to remain in place. I can do this all in NT exchange/proxy with my eyes closed, but not in Linux, at least not in a very short period of time. I can offer the hardware, hosting, storage space, but I'd need a few hands helping me set all this stuff up properly, and reliably.

John, can you give us an idea what the minimum requirements would be for a machine to handle the lists in non digest mode and the WWW traffic? I guess a 100 Mbit/sec connection would also be good? FYI, the physical location of the machine would be in Dallas/Ft. Worth. If we decide to go this route I'll volunteer to purchase a machine (once I know what's needed) and get it delivered. I'll accept $10 donations up to the cost of the machine also :-). I'm also NOT a linux head so I'll need someone's help in the Austin area to get it set up and configured before delivery. Personally, I'd prefer this approach over one of the free public hosting sites because it gives us total flexibility in terms of CGI, ftp site, etc. --steve Orin Eman wrote: > > > I sent a reply to diy_efi but it looks like most of the discussion is on > > the other lists.

I | guess a 100 Mbit/sec connection would also be good? Hi Steve, The load is on the order of 40MBytes+ (on heavy days more like 120M) each day. I estimate (with diy_efi out of digest mode) from last month that there are roughly 580k mail messages each month. Operating these lists in _not_ a small task; a dual channel dedicated ISDN would be the minimum service if we didn't co-locate. Please make this point clear to your sister... our bandwidth usage is not insignificant. I can run the machine from here, BUT... most likely, someone will have to physically touch it once a year to do OS upgrades. I would recommend that I have the machine for a week or two to set it up before shipping to Dallas. john gwynne From diy_efi-owner Thu Nov 11 13:55:15 1999 Return-Path: Received: (from root@localhost) by esl.eng.ohio-state.edu (8.9.3/8.9.3) id NAA09912 for diy_efi-outgoing; Thu, 11 Nov 1999 13:55:15 -0500 Received: from the.hoser.com ([204.233.135.19]) by esl.eng.ohio-state.edu (8.9.3/8.9.3) with ESMTP id NAA09903; Thu, 11 Nov 1999 13:55:05 -0500 Received: from localhost (eclark@localhost) by the.hoser.com (8.9.3/8.9.3) with ESMTP id NAA21083; Thu, 11 Nov 1999 13:58:40 -0600 Date: Thu, 11 Nov 1999 13:58:40 -0600 (CST) From: Eric Clark To: diy_efi@efi332.eng.ohio-state.edu, gmecm@efi332.eng.ohio-state.edu Subject: domain name Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-diy_efi@esl.eng.ohio-state.edu Precedence: bulk Reply-To: diy_efi@efi332.eng.ohio-state.edu I'll give a sub domain off of hoser.com for the diy_efi, efi332, and gmecm sites. efi.hoser.com or whatever the list wants. -Eric From diy_efi-owner Thu Nov 11 14:48:48 1999 Return-Path: Received: (from root@localhost) by esl.eng.ohio-state.edu (8.9.3/8.9.3) id OAA10671 for diy_efi-outgoing; Thu, 11 Nov 1999 14:48:48 -0500 Received: from mumert.com (clgr002050.hs.telusplanet.net [161.184.96.18]) by esl.eng.ohio-state.edu (8.9.3/8.9.3) with SMTP id OAA10668 for ; Thu, 11 Nov 1999 14:48:47 -0500 Received: from PII [10.127.32.139] by mumert.com [10.127.32.138] with SMTP (MDaemon.v2.8.5.0.R) for ; Thu, 11 Nov 1999 12:48:31 -0700 Message-ID: <001f01bf2c7d$b84dbde0$8b207f0a@mumert.com> From: "Dave Mumert" TO: Subject: Mailing List Hosting Date: Thu, 11 Nov 1999 12:48:26 -0700 MIME-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 7bit X-Priority: 3 X-MSMail-Priority: Normal X-Mailer: Microsoft Outlook Express 5.00.2314.1300 X-MimeOLE: Produced By Microsoft MimeOLE V5.00.2314.1300 X-MDaemon-Deliver-To: diy_efi@efi332.eng.ohio-state.edu X-Return-Path: Dave@mumert.com Sender: owner-diy_efi@esl.eng.ohio-state.edu Precedence: bulk Reply-To: diy_efi@efi332.eng.ohio-state.edu MailingLists.org offers non-profit mailing list hosting for $100 per year.

It's been suggested that FreeBSD would be better for us than Linux. Either is OK by me, but I'll take the FreeBSD side of the argument unless someone really persuades me otherwise. To get things up and running fast, I'd suggest the machine be put in place with nothing much more than the OS, secure shell and outgoing ftp. I'd rather have our own server than the free lists.

I am willing to provide web and ftp services for free, I am a full time web programmer and can do custom cgi perl or php scripts for the site. I'm still trying to negotiate a place to install a linux machine provide mail services. I use linux both at home and at work and on my servers that run hoser.com, and have a lot of experience in this.

Anyway it will probably use the honda/toyota (NTK) UEGO. From the technical papers and patents on these devices they seem pretty straightforward. Rather than reinvent the wheel, if there is a design for an analog output interface for this device it would be much appreciated. Otherwise I will proceed to design and build one, it will probably have a non linearized 0 - 2.5V output corresponding to the 13:1/20:1 mixture.

I've been browsing Dell and Compaq WWW pages and it looks like we can get a Celeron 64MB type machine for about $1000. I keep hearing about Linux pre-installed but the only OS options I've seen are 98 and NT. Guess we'll need a red-hat CD also. I'll let John handle that if we go this route. As far as one-list and the other free services, the main problem I see is limited file space (5MB) and lack of CGI support. I think we'll run into that at most of the free services which is why I think a dedicated machine is the way to go. Our current machine (according to uname -a) is an "i686", whatever that means (PPro? PII)? It was staggering under the load of non-digest diy_efi, so the machine requirements apparently aren't trivial.

I'd be interested in what you can do with our archives. The current engine is freeWais, and I've had a hard time getting it to recognize and extract fields from our archives. It'd be very nice to be able to search by subject, author, and within date ranges. A search language like altavista uses would also be nice. The archives are huge though, like 4 MB in size each month, at least before digeset mode set in. And that's only diy_efi. Any database would have to be able to handle large sets quickly.

The system that would be doing the hosting is just a Pentium 166. It's got relative buckets of RAM (128MB) however. The IP address never changes. Another word: It is absolutely irrelevant whether FreeBSD or Linux (or Solaris) is used for this purpose. FreeBSD was more stable than Linux... in 1995. This is no longer true, both of them are now quite bulletproof. I have been using Linux since 1996 (including as the sole operating system at an ISP) and have managed to crash it a total of once (while pushing the limits of some hardware drivers). I've actually had more disk failures than OS crashes.

On to my question for the group.... I have an '83 GMC pickup that I recently put an '85 305 TPI system in, it is a completely stock setup with an '870 ECU. The other night I converted it to a 1227165 ECM it came from a 4 cyl S10 I believe (also used in '86 - '89 TPI camaros and firebirds). I cut the original memcal in two, left the 2 chips from the 4 cyl in and put my '89 TPI EPROM in place of the 4 cyl EPROM and changed the pins in the harness that needed to be changed. Problem is the truck would not start. It would hit once then die. If I removed the EPROM and left only the two other chips from the original memcal, it would start and run, not very well mind you, but it would run. Putting the EPROM back in causes it not to start. The EPROM was burned by me, I verified it, everything seems OK. Does anyone know if the 4 cyl (other 2 chips in the memcal) will cause this? Or am I fighting a greater problem or maybe an ECU that the magic smoke has escaped from. The new ECU came from the salvage yard.

Go for a full Pentium II or Pentium III machine with a MINIMUM of 128MB of RAM. 256 is better. Use Linux if you like, but the robustness and ease of administration of an NT small business server can't be beat. Full remote admin over the web in your browser. By robustness I mean throw in 2 18GB UDMA ATAPI (ide) drives, mirrored, and even hear in Canada with our CanukPesos the storage component is only about 500 clams. That is with top line Fujitsu drives - if you want to use WD or seagate the price may be lower, but you only get what you pay for. Buy a good brand name motherboard - I use DFI and won't touch Acer, Asus, or Gigabyte. Don't nickel and dime the small stuff - the difference between "real good" and "dung-pile" is only a few percent overall. Excellent may cost significantly more. Get a good fast ATAPI CD - I'd go for a CDRW and use it for archiving as well. More durable than tape. You don't need fancy graphics or sound.

Firstly, with the engine running use a rag and block the intake at the throttle body. Do your best to stop any air entering the engine. If the engine still runs you have a vacuum leak. Now get a length of rubber tubing and carefully listen for the source of the leak. If this doesn't work it's time for the carb cleaner. Gently, and I mean really gently, spray a few drops of cleaner around any possible leak sites. Not just the plenum but things like the brake power booster the evap canister, just about anything that is vacuum operated. If the revs rise, you have your leak. Disconnecting the O2 sesor helps, by not allowing the ECM to adjust the mixture to compensate for the spray. A few things to note Carb spray burns real good, be careful. Never assume there is only one leak. The power steering pump can sound like a vacuum leak.

Why SunSite and not our own server? 1. No personal relations, which could stop us one more time. 2. Reliable service - backup/maintenance. 3. Nearly free capacity (Disk and traffic) 4. Nice "kick-start" with the search engine, new archive for mail etc. 5. Free!! It's allways possible to move to our own server by paying some money to some sort of ISP. I can handle the setup and transfer with SunSite if you like. I'll start with the website and after that i'll setup the mailling list. Administration could be split on different persons.

Sender: owner-diy_efi@esl.eng.ohio-state.edu Precedence: bulk Reply-To: diy_efi@efi332.eng.ohio-state.edu Nobody has yet suggested we turn the DIY-EFI list into a Usenet Newsgroup. This may be a stupid idea, but I won't know until somebody explains *why* it's a stupid idea. Pro: 1) Distribution is decentralized, automatic, and free to posters and readers. 2) Most newsreader programs make it easy to avoid reading stuff that doesn't interest you. Similar to the non-digest form of this list. 3) Network News Spam seems to be relatively well-controlled nowadays (at least on the groups I follow); spam that gets through is easily ignored. Con: 1) Many folks on this list may not be familiar with Usenet News, and/or unable to receive News. 2) Distribution is not instantaneous; postings may take an extra day or two to reach far-flung recipients. 3) I don't personally know how to get a new newsgroup constituted. Surely someone reading this does; perhaps that intelligent person can explain to me, and the list, Gently, why this is a stupid idea :-) . Asides: 1) Still need a low-bandwith server somewhere to archive digests and serve ftp requests. Interested readers unfamilar with Usenet News are advised to try reading "rec.autos.tech" to see what News is like. I believe both Netscape Communicator and Internet Explorer have a facility for reading News. Reading Network News is very similar to reading the non-digest form of this list, except that you must use a "Newsreader" client, instead of an "Email" client. Here are approximate directions to subscribe-to and read "rec.autos.tech" using Netscape Communicator (v4.7 under Solaris, anyway). Sorry, I'm not familiar with Internet Explorer, but I'm sure it's similar. a) Pull down "Communicator: Newsgroups". b) In the new Newsgroups window that pops up, pull down "File: Subscribe". c) In the newest window, locate the "rec.*" line, and open it. d) Scroll down to "rec.autos.tech" and highlight it. e) Click "Subscribe". f) Click "OK". The topmost window will go away. g) Doubleclick the newgroup you chose in step d). A new window should pop up, and if everything worked, you should be able to "read News." stuart hastings From diy_efi-owner Mon Nov 15 13:49:39 1999 Return-Path: Received: (from root@localhost) by esl.eng.ohio-state.edu (8.9.3/8.9.3) id NAA23917 for diy_efi-outgoing; Mon, 15 Nov 1999 13:49:39 -0500 Received: from web902.mail.yahoo.com (web902.mail.yahoo.com [128.11.23.77]) by esl.eng.ohio-state.edu (8.9.3/8.9.3) with SMTP id NAA23914 for ; Mon, 15 Nov 1999 13:49:38 -0500 Message-ID: <19991115184933.21890.rocketmail@web902.mail.yahoo.com> Received: from [137.53.165.68] by web902.mail.yahoo.com; Mon, 15 Nov 1999 10:49:33 PST Date: Mon, 15 Nov 1999 10:49:33 -0800 (PST) From: Carter Shore Subject: Re: DIY_EFI Digest V4 #644 To: diy_efi@efi332.eng.ohio-state.edu MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Sender: owner-diy_efi@esl.eng.ohio-state.edu Precedence: bulk Reply-To: diy_efi@efi332.eng.ohio-state.edu I'm in Portland OR this week, rented an ISUZU Amigo.

Strictly speaking as the Administrator of a Prism3000 based network backup enviorment to even propose the CDRW is as this guy puts it "more reliable" is so far from the truth its not even funny. The real world is more like this, the life of a write head inside a cdrw drive is somewhere around 2 years MAX under heavy usage aka archival work. The life expectancy of a DLT tape drive is around 5 years up to 10 if your archival is weekly not daily. As far as durability another load of BS. cdroms are suspectbale to all kinds of damage,dirt,heat,scratches etc etc. Tape is pretty much magnetic and physical damage. a lot more durable than cd's will EVER be.It shocks me how unaware some NT type really are about the REAL world. -- Ned Williams UNIX Administrator Systems Integration Group IMS Health - Strategic Technologies From diy_efi-owner Mon Nov 15 17:25:13 1999 Return-Path: Received: (from root@localhost) by esl.eng.ohio-state.edu (8.9.3/8.9.3) id RAA28224 for diy_efi-outgoing; Mon, 15 Nov 1999 17:25:13 -0500 Received: from the.hoser.com ([204.233.135.19]) by esl.eng.ohio-state.edu (8.9.3/8.9.3) with ESMTP id RAA28218 for ; Mon, 15 Nov 1999 17:25:11 -0500 Received: from localhost (eclark@localhost) by the.hoser.com (8.9.3/8.9.3) with ESMTP id QAA14702 for ; Mon, 15 Nov 1999 16:25:08 -0600 Date: Mon, 15 Nov 1999 16:25:08 -0600 (CST) From: Eric Clark To: diy_efi@efi332.eng.ohio-state.edu Subject: Re: DIY_EFI Digest V4 #645 In-Reply-To: <199911152000.PAA25437@esl.eng.ohio-state.edu> Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-diy_efi@esl.eng.ohio-state.edu Precedence: bulk Reply-To: diy_efi@efi332.eng.ohio-state.edu On Mon, 15 Nov 1999, DIY_EFI Digest wrote: > Date: Mon, 15 Nov 1999 10:44:23 -0800 (PST) > From: Stuart Hastings > Subject: rec.efi.diy newsgroup? > > Nobody has yet suggested we turn the DIY-EFI list into a Usenet > Newsgroup.

Signal to noise ratio is really low on almost every newsgroup. A private nntp server that is NOT part of usenet would not be a bad idea.

There are also issues with some ISPs not carrying all of the newsgroups, and with loosing messages if you don't check the NG very often (like during a vacation). Also note that, when accessing USENET for the first time, Netscape may 'freeze' while it downloads the latest list of newsgroups from your ISPs server.

It's minus any EFI stuff and had a new edelbrock intake. I've sold teh intake and vortec heads to a friend so I can put my alum. rpm's or afr's on it (haven't decided which, will sell whichever I don't use) etc. It's going into my 280ZX which has a 327 right now, so the aluminum/lighter weight is important for my weight balance/steering effort etc. Back to my q. This engine has a plastic front cover and the seller told me what looks like a similar size for a 5/8 heater hose hookup on it's bottom pass. side is a crank angle sensor! So after I got it home my heads spinning on the chance I might be able to make a distributorless ignition system without breaking the bank assuming I understood right this crank is already setup for this?? I"m v. green on ignition's so any url's etc are v. welcome. I have a crane HI-6 new gathering dust and a used holley 4Di system. I planned to use the 4Di system for this motor and was going to ask if the crane HI6 unit can be hooked up w/ the 4Di? Now I need to know how/if what I need to go distributorless?? I have a set of MSD universal wires I was going to cut to replace my current worn out MSD's but now I'll hold off till I know which direction this ignition is going to take. PS the motor will likely be run on a performer 600cfm for the first while till I sort out some other issues on my EFI list like new fuel lines/laptop/time to sort out etc. So the any changes if I go distributorless w/o the 4Di are of interest as well (the 4Di can control the timing curve as I understand it).

However, while inspecting the joints between the plenum and engine, I noticed a large 3mm gap at the first cylinder. I repositioned the rubber sleeve and the car is running and idling again. Needless to say I'm psyched! My little mishap with the injector connector which caused the backfire was ironically my saving grace: the backfire blew the sleeve far enough out of place that even an idiot like me could see the gap. After I repositioned it, I could no longer hear the hissing sound here. I'm concerned, however, with the fact that the sleeve is spanning a gap of about 2 to 2.5 cm and just barely covers it. It seems that the plenum chamber isn't close enough to the engine here. Any tips on how to adjust the positioning of the plenum here? The idle is still a tad low, but basically the same as when I purchased the car. I think it would be better if the plenum were properly positioned, but maybe not. It just seems that malpositioning here would cause subtle airflow changes which could adversely affect performance. Also, the AFM currently on the car is not the original. The previous owner replaced the original with a refurbished one, but then found that the original wasn't bad after all. I still have the original one. The refurbished one feels much stiffer than the original, though still has smooth operation. The original one has noticably less resistance in its flapper opening. Even after detensioning the spring by 3 notches in the refurbished one, it's still a lot tighter than the old one. Should I put this old one back on? Would this improve idle/performance?

I disconnected the battery, but this didn't help. However, while inspecting the joints between the plenum and engine, I noticed a large 3mm gap at the first cylinder. I repositioned the rubber sleeve and the car is running and idling again. Needless to say I'm psyched! My little mishap with the injector connector which caused the backfire was ironically my saving grace: the backfire blew the sleeve far enough out of place that even an idiot like me could see the gap.

(I know there is a lot of debate over this) Thanks, Derek '90 Alfa Spider [CPutter] Congrats. As far as I know the Bosch units controlls the idle speed by means of a electronic by-pass valve. The speed is sensed from the engine and is then regulated to the specifically programmed value. In som of the bosch training manuals that I have seen they specifically state that the idle speed is not adjustable. (Maybe it is Hard-coded in the EPROM). Another thisg you can check is if the by-pass valve is actually in operation. Close down the by-pass hosse while the engine is ideling, if the speed drops, and then when it is openned the speed goes higher than normal, then the closed loop control is still in-tact. (On my astra i can close this hose by pressing it with my thumb an finger, I do not know your set-up).

Hopefully one with boost retard built in. I've started developing some PIC code, but I'm not an electronics type. There seems to be two ways to go. One is to intercept the crank trigger. It has 35 teeth and one missing one, for a pulse every 10 degrees. That makes writing the retard code a little tricky, as more than 10 degrees of retard would span pulses. The other way is to use the coil triggers as inputs. I'm not sure if 4 identical chips should be used, or if one chip should process all inputs. Does anyone have any ideas on which way I should go. I'm a programmer by trade, and the PIC assembly language is pretty easy to work with. Any help you can offer will be greatly appreciated.

So now i need a wiring harness.I contacted Howell and Painless.Howell says a speed sensor is not required for the engine to run smoothly.Matt at Howell says that it will only affect the EGR,and not the IAC. Painless says that the engine will always be stalling on deceleration. My question is this.How will the IAC motor reset its position if it doesn't have a speed sensor input?It is my understanding that this happens when the vehicle reaches 30 MPH. There is no smog testing where i live. So,do i need a speed sensor or not? Anyone know of any good websites dealing with 4.3 swaps and such?

The 10 degrees resolution is actually not a hindrance. Once the engine starts cranking your first goal is to determine TDC of Cyl. 1. You find this by counting how long it takes to go from tooth to tooth and comparing that to the last time. In PIC assembler you can do this easily by setting up the timer and counting how many times it rolls over from a initial value. At 6600RPM each tooth will take about 250uSec so you have to factor your timer resolution to have a reasonable count at that RPM. At cranking you've got almost forever in PIC cycles. Once you find the TDC each successive tooth gives you a 10 degree interval that translates into engine RPM. Count each one and when you reach 18 you know you are at BDC. Actually, if you set your divisor correctly and assume RPM stays fairly constant over a 180 degree stroke you can use these timer ticks to determine when to fire the spark plug.(4 cyl engine). For example: for an 8cyl engine you fire every 90 crank degrees. This is 9 teeth. At tooth #4 set a variable that matches what the count should be at your desired ignition point; turn on current to the coil(Dwell period). When the count matches, fire the plugs by removing current through the coils (waste spark). Fire them again at tooth 9, 18, 27 and 35( + tooth gap) just in case you missed the previous count. If you don't get engine RPM after your timer as overflowed a few times then the engine has stopped. Shut off the current to the coil in case it's still on to avoid burning out the coil. Hope this makes sense. I even added knock detect and retard by using a knock sensor and using an input into the PIC to change what constant was added to the delay. This retarded the ignition to avoid knock.

I've checked out the PIC'N'POKE page, and a few other web resources. One degree of delay is equal to: 60 / (RPM * 360) seconds and RPM = 60 / time between pulses These two simple equations can be scaled in millisecs or uSecs for ease in working with a PIC controller. But I keep getting lost in the interrupts for processing 4 inputs triggered by a falling edge. One cycle is the time between falling edges for one input. Do you think I should zero out TMR0 at the start of input #1, then use TMR0 to track the time. I.E. Input #1 time = TMRO at interrupt, Input #2 time = TMR0 at interrupt - Input #1, etc. ?? There has to be a better way of doing that :) Thanks, David -----Original Message----- From: DIY_EFI-Digest-Owner@efi332.eng.ohio-state.edu [mailto:DIY_EFI-Digest-Owner@efi332.eng.ohio-state.edu] Sent: Friday, November 19, 1999 15:00 To: DIY_EFI-Digest@efi332.eng.ohio-state.edu Subject: DIY_EFI Digest V4 #650 DIY_EFI Digest Friday, November 19 1999 Volume 04 : Number 650 In this issue: Spark retard for EEC-V (DIS) flowbench See the end of the digest for information on subscribing to the DIY_EFI or DIY_EFI-Digest mailing lists. ---------------------------------------------------------------------- Date: Fri, 19 Nov 1999 07:41:14 -0500 From: "Posea, David G, SITS" Subject: Spark retard for EEC-V (DIS) has anyone thought about building a programmable retard unit for a DIS ignition.

I need to output crank signals instead of firing a coil, but the concept is the same. This is an add-on box, not a complete controller. But based on your input I think this will work: find TDC zero the timer on timer interrupt increment high byte of timer (16 bit resolution), if count = 36 make sure a tooth is missing. Zero timer at TDC on input interrupt store tooth number, timer value, and last two timer values. I would store all the tooth times, but would run out of ram. The last two should be plenty for up to 15 degrees of retard. main loop keeps track of output pulse count, and compares the timer to the stored timer for that tooth. If the delay is reached, send an output. If not, keep looping. I'll need an A/D converter for boost value (GM MAP sensor), and a lookup table for the delay based on rpm, but that should be easy. It may be even easier just to calculate the delay on the fly with a 20mhz processor. I know I can use the pre-scaler to slow down the timer, but should I do that, or increase the timer resolution to 24 or 32 bits? As always, thanks for the help!!

Using a threaded newsreader would make wading through the traffic on this list a breeze. It also makes maintaining a mailing list unnecessary as well stopping problems with vacation programs and invalid email addresses we've had in the past. Another reason I like the idea is that it obviates storing messages locally. On-access serving should also cut the I/O requirements drastically. Is there anyone on the list who doesn't have access to a newsreader (e.g. netscape or outlook express, or equivalent UNIX software?) The only other concern I would have is, as others have stated, that it makes it easier for spammers to harvest email addresses, although this is already quite possible by greping the current archives...

Instead of winding one piece of wire around the core for n turns you wind two wires around the core for n turns. Keep it nice and neat and it looks like one long piece of wire but has two connections at one end of the winding and two at the other end of the winding. This makes for more efficient coupling than once winding put on top of the second winding.

BTW, my current project right now is heavily modifying my 1982 Corvette. I realize this is an arduous task considering the nature of the Cross-Fire Injection system, but I have done my research (some of it from here, others from books and individuals) on tricks to improve it.

This list has only been in digest mode for a short time. It worked quite well before that, and I would like to see it as a regular mailing list again. As far as your crossfire goes, there's a few of us who've done some crossfire work. To remove a bunch of the "arduous" from your crossfire, use a 1227747 ecm from a pickup. It's a real straightforward swap. I've got mine in a 57 Chevy pickup on a 302, there's a couple other guys here that are running or working of crossfire also. Be sure and read the tuning tips, they were written by a guy getting 13's in a Camaro with crossfire.

Jacobs and MSD both make a 4-channel CDI unit for waste-sparking an 8 cylinder. I think MSD and Crane make a 2-channel unit for firing a four cylinder. One downside to MSD, is their 6A series coil drivers are current limited, and incapable of driving really hot, low impedance coils. If you're assembling an ignition, you might as well get your money's worth, so I'd recommend Jacobs or Crane. > 2) I found this waste-fire coil picture here on efi332: > ftp://efi332.eng.ohio-state.edu/incoming/coil.jpg > Anybody know what this coil is from?

Although this kit was developed specifically for the Toyota 3.4 engine many people still complain of drivability problems including high RPM leanness. The 6psi kit originally came with a rising rate regulator, which has since deleted, and the application list changed to include only 97 and newer trucks. I have a 96. As a result, I have been trying educating myself on the vehicle's fuel system to determine if it can handle the supercharger. My studies have lead me to the following questions which I hope the EFI experts on this list could answer. 1) Based on the equations I have seen on this list, the stock 250cc/min injectors should be able to flow enough fuel to handle 6psi boost at 5500 RPM. This assumes a fuel rail pressure of 60-65psi. Is this correct? 2) Is there a way to determine when airflow will exceed the MAF and ECU's ability to maintain the proper A/F mixture at stock fuel pressure? I would like to have some idea when (RPM @WOT) to begin boosting fuel pressure prior to installing the supercharger. 3) Is there a simple way to increase fuel pressure based on boost pressure and engine rpm? I would like to avoid running overly rich, due to increasing fuel pressure based strictly on boost, while still within the MAF control range. I guess if I'm really lucky, one of the list's readers will have installed and "dialed in" one of these TRD superchargers.

The data for the 78 Trans Am and the Pontiac 6000 was gathered by testing on those actual vehicles. In addition, I simulated test conditions for those which could not easily be obtained on a real vehicle by using variable resistors to create input signals in place of the MAP, Temp, TPS and EGO sensors. While using this test setup, I used a function generator to make a pulse that was equivalent to the SP from the ignition coil (to simulate the RPM input). I will try to post more info on the simulator setup I used when I get the chance. > and if its possible to use the crankshaft sensor instead of an inductive > pick up of the spark pulse. the crankshaft sensor is a hall effect sensor > used in rover cars. Yes, I don't see why not.

No. 6.3v would be fine since that only operates on a 5v circuit. Capacitor voltages are maximum ratings. You could use a 25v or 50v cap. if you wanted (though it would physically be a bit large). The tough-to-find resistors can be substituted with values that are within 5% usually. The .5ohm or .1ohm resistors may be substituted with a piece of wire that has that resistance (though electronic supply stores usually sell these, as does digi-key). Good luck.

The first hurdle is that they have to find out about the list, and subscribe to it. The second is that now someone (the list manager) has an accurate e-mail address for them.

It was a while ago, but it was in demand then so e-mail me if you want it and I can send it to you. Now, my current problem is very interesting. I have three proms, BUA, ABTD and AANM all which suit a corvette... either '87 or '86. Anyhow, I wanted to write my own little program to get the aldl stream because I wanted to manipulate the data a bit more just to try some things. I know that the procedure to link to this type of prom is a little wierd. This is the procedure that I'm going through. ECM is initially in 160 baud 10k resistor to put prom in ALDL mode Prom starts to put out a 25 item 160 baud stream At the end of the stream the ECM listens for 50ms for a 8192 request Once a request is sent, the ECM stays in 8192 baud and everything is sweet. RIGHT, everything seems to work perfectly in Diacom for all three chips, however when I use my device it only links with ABTD. I've tried everything possible and I've narrowed things down a little. I've used Diacom to put all three proms in 8192 baud and after that I have no problem linking with my device, so that must mean that the stream requests and reads are a.o.k. Then I thought, maybe the resistor value was wrong, so instead of plugging Diacom's resistor lead into the plug, I substituted my resistor. Diacom worked perfectly, that means that my resistor was also ok. I then checked to see if Diacom was sending anything else... I didn't pick up anything at 8192, except a 0xFF... maybe a falling/raising edge or something? I think THIS is my problem. One more thing, that Diacom worked perfectly with all proms also indicating that my ECM, loom, computer and other stuff was ok. So, is my presumption correct that Diacom is sending something else? Or is my device faulty or something? I can't seem to figure this one out... Too many late nights. If only I could swap get proms to the 8192 polling mode, then everything would be ok. One more thing was that I was unsure about the VATs having to be bypassed. Diacom didn't have a problem, and also that fact that Diacom doesn't put anything into B6 (VAT pin) means that it should also be ok to get the stream while VAT is looking for that startup signal. If anybody could give me any hints to my problem that would be great. Andrew Wakeling.

I have a DIS-4 on my car. The problem is there is no provision for advance/retard based on a MAP reading. Crane makes a HI-6D2, which will fire two coils, and has an optional boost (MAP) retard box. Does your airplane engine already have an ignition, or do you need to build one from scratch? I'm looking at building a retard box for use with my stock Ford DIS/MSD DIS-4.

I'm intending to install a FMU (rising rate FP regulator) along with the supercharger to increase the pressure to the 60 to 65 psi range. My major worry is how to set up the FMU so it does not boost the FP prematurely. 2) Do you know the range of the Vf signal and how it relates to either air or fuel flow? 3) I think the "Boost a Pump" you mention it triggered by boost pressure, not RPM. But I assume it could be modified to also trigger off of RPM. What I think is necessary for the best driveability and performance would be to raise the FP in two stages. First, increase FP 1/1 to compensate for manifold pressure, and let the AFM and ECU control A/F. When A/F starts to lean out at high RPM, increase FP to 60-65 psi. 4) I have traded e-mails with two of the 4Runner Webringers with TRD superchargers. They have solved their driveability problems by switching to aftermarket injectors, AFM and ECU. This solution is out of my price range and I am not sure it is necessary. Thanks, Bob Wimmer >>> 11/22 3:40 PM >>> >> This assumes a fuel rail pressure of 60-65psi. Is this correct? << It was my understanding that EFI pressure ratios were lower - like closer to 45psi. I may be wrong as I am more familiar with the 22RE than the later V6 engines. >> 2) Is there a way to determine when airflow will exceed the MAF and ECU's ability to maintain the proper A/F mixture at stock fuel pressure? I would like to have some idea when (RPM @WOT) to begin boosting fuel pressure prior to installing the supercharger. << Im curious if the later EFI systems still use the Vf trim signal. If so - this will give you a real close look at what the OEM EFI thinks is going on and how much adjustment is still avail (or NOT avail as the case may be). See if there is a connector marked "Vf" in the check connector box next tothe fuse box in the engine compartment >> 3) Is there a simple way to increase fuel pressure based on boost pressure and engine rpm? I would like to avoid running overly rich, due to increasing fuel pressure based strictly on boost, while still within the MAF control range. << I think there is a "Kenne Bell" "Boost a Pump" device that does this. Most people on this list appear to want to build their own decives from chips though. >> I guess if I'm really lucky, one of the list's readers will have installed and "dialed in" one of these TRD superchargers. << Check out the 4Runner Webring.

You just have to accurately estimate the length of wires to twist together. And although winding a simple toroid is unwieldy compared to an E and I core, the number of turns in a switchmode converter is usually low. FWIW, I used several Delta Mark 10 CDI units on my race and street cars for many years with no failures. The kits were very simple to assemble. I have not seen their ads in quite a while, and net search yielded nothing, so I guess they are gone. --- DIY_EFI Digest wrote: > > DIY_EFI Digest Sunday, November 21 1999 > Volume 04 : Number 654 > > > > In this issue: > > RE: rec.efi.diy newsgroup? > Re: DIS > > See the end of the digest for information on > subscribing to the > DIY_EFI or DIY_EFI-Digest mailing lists. > > ---------------------------------------------------------------------- > > Date: Sun, 21 Nov 1999 08:34:42 -0800 (PST) > From: Mark Wilcutts > Subject: RE: rec.efi.diy newsgroup? > > I'd like to chime in late here for support of the > private news server > idea.

Thanks for any help/insight :) Those sound like pretty big whoppers, but the Cherry Semi CS-453 Injector Solenoid Drivers might still work for you. They are a 4Apeak/1Ahold devices, which I've used the smaller variety of (CS-452) on some ordinary peakNhold mpfi injectors. They have alot of nice attributes going for them (logic-level inputs, tho the inputs can swing between supplies, load dump safe, wide supply range, heat sink tab is ground), and yes you could easily drive their inputs from a previous ECM output driver for sat injectors, except the polarity is wrong (they're low = on), and would require an inversion (CS drivers are high = on); that is easily done, tho. After talking to Dr. Pelican about the Accel box, I was thinkin bout making some of these as another product; but it appears the Accel box also includes timing-per-injector to allow pulse stretching/narrowing. The real question I have is just how necessary/desirable is THIS particular pulse stretching/shrinking feature, or would there simply be a place for 4/6/8 ganged "translators" from SAT to PnH? Admittedly, in EITHER case, these gizmos are mostly a packaging issue, not much of a circuit design problem, so it's not atoll clear it makes sense to "productize" them. The thermal/vibe design of the packaging is probly the most important thing, really. I guess I'm really wondering just how safe/effective/useful/sane it is to consider tweaking your fueling by an overall shrink/stretch of the injector's pulse width? Sounds like an awfully global whack to the fuel map; under what conditions is this hitting the nail on the head, or is this a case of the proverbial "hitting a big nail, not quite on the head"?

Thanks for any help/insight :) I (and lots of other GN owners) have successfully used the batch fire DFI box with P&H injectors. I always thought it was designed for them, though admittedly I never took it apart or called Accel about it. No problems thus far. If you want to mod it cheap, you could do like I do with the stock GN ECMs; take the drivers in the DFI box; replace them with the CS452/3s, and put the extra bias resistor/zener on perf board inside the case. If they're TO-220 cased transistors, you can put the Cherry drivers in their place and bend the extra pin up to connect 'em.

First, Does anyone know of any of the current aftermarket EFI companies offering anti-lag functions like on the WRC ralley cars? I understand the computer just altered fuel and ignition timing during shifts to fire while the exhaust valve was opened. The result was that some of these cars could produce 15psi of boost at idle. The amount(?) of anti-lag was cockpit adjustable. Second, and more importantly, I'm having a bit of trouble with my Porsche 944 turbo. I've replaced the stock, very restrictive, flapper box with a large hot wire MAF using Split Second ARC-2 to filter the signal. The car also has a larger turbo, headwork, nitrous etc. The problem I'm having is the large turbo is apparently causing some sort of pulsation in the MAF. The resulting "noise" is causing some off-idle drivability problems. Once I apply more than 1/4 throttle, the signal to noise ratio improves and the car seems to perform fine. I was in the process of putting together a simple op-amp circuit to either limit maximum voltage from the MAF sensor when throttle is less than 1/4 or so, or replace the MAF signal with an amplified throttle signal up to 1/4 throttle. I realize the latter wouldn't compensate for load. My question is, is there anything on the market that I could use instead of making it myself? Prefferably something digital. I've been told that I'd have to buy a complete EFI system. Which might be worth it if I could also get Anti-lag and boost-control functions. Does my solution make sense? Any input you could provide would be very helpfull. The car has any early form of Bosch Motronic. Before some recent modifications the car was dynoed at 320 rear wheel HP without nitrous and 395HP 435TQ with nitrous.

The voltage ranges from 0v to 5.0v in .5v incriments. This value is based upon the ECM's learned fuel adjustment over time. If there is no adjustment to the base fuel schedule, it will read 2.5v. If the mixure is too lean and the injectors need to be richened, the voltage will increase in .5v steps up to 5.0v and lower than 2.5v if the mixture is leaned out due to a rich 02. I am not sure how reliable this number will be for WOT tuning as there is a time element to determine this voltage. It should be a good number for regular driving though. I will try to find out more for you from TRD. Scott Date: Tue, 23 Nov 1999 12:32:46 -0500 From: "Robert Wimmer" Subject: Re: TRD Supercharger Ed: 1) Your right that the stock FP on the 3.4 engine is 38-44 psi. I'm intending to install a FMU (rising rate FP regulator) along with the supercharger to increase the pressure to the 60 to 65 psi range. My major worry is how to set up the FMU so it does not boost the FP prematurely. 2) Do you know the range of the Vf signal and how it relates to either air or fuel flow? 3) I think the "Boost a Pump" you mention it triggered by boost pressure, not RPM. But I assume it could be modified to also trigger off of RPM. What I think is necessary for the best driveability and performance would be to raise the FP in two stages. First, increase FP 1/1 to compensate for manifold pressure, and let the AFM and ECU control A/F. When A/F starts to lean out at high RPM, increase FP to 60-65 psi. 4) I have traded e-mails with two of the 4Runner Webringers with TRD superchargers. They have solved their driveability problems by switching to aftermarket injectors, AFM and ECU. This solution is out of my price range and I am not sure it is necessary. Thanks, Bob Wimmer >>> 11/22 3:40 PM >>> >> This assumes a fuel rail pressure of 60-65psi. Is this correct? << It was my understanding that EFI pressure ratios were lower - like closer to 45psi. I may be wrong as I am more familiar with the 22RE than the later V6 engines. >> 2) Is there a way to determine when airflow will exceed the MAF and ECU's ability to maintain the proper A/F mixture at stock fuel pressure? I would like to have some idea when (RPM @WOT) to begin boosting fuel pressure prior to installing the supercharger. << Im curious if the later EFI systems still use the Vf trim signal. If so - this will give you a real close look at what the OEM EFI thinks is going on and how much adjustment is still avail (or NOT avail as the case may be). See if there is a connector marked "Vf" in the check connector box next tothe fuse box in the engine compartment >> 3) Is there a simple way to increase fuel pressure based on boost pressure and engine rpm? I would like to avoid running overly rich, due to increasing fuel pressure based strictly on boost, while still within the MAF control range. << I think there is a "Kenne Bell" "Boost a Pump" device that does this. Most people on this list appear to want to build their own decives from chips though. >> I guess if I'm really lucky, one of the list's readers will have installed and "dialed in" one of these TRD superchargers. << Check out the 4Runner Webring.

You may want to look for Technological Arts they have an inexpensive board for using a HC11 with a breadboard. Check out programing 101 and the GMecm list.

For those not in the know, snapping the throttle open at a low rpm idle causes a 1/2 second lean-out stumble. This is worse the lower rpm you go, and worse the more cam overlap you run. I run across bazillions of different theories, all of which I've decided are crap (feel free to correct me though). e.g. 1) The flow change lags behind the pressure change. Bollocks. That would make it run rich, and besides the pressure change is CAUSED by the flow. 2) The intake runners have columns of air that need to be accelerated to the new conditions. Bollocks. That would also make it run rich, and besides the flow always tops between intake cycles anyway. 3) There is a delay getting the fuel in the port to the cylinder. Bollocks. Its squirted directly on the back of the valve, at low rpm it'll just run in under the influence of gravity, when the valve is opened. 4) Manifold wall wetting effects Bollocks. This is port injection, the walls don't ever see fuel. 5) The vapourised fuel in the port condenses because of the pressure increase. Maybe, but it seems that this would not cause a major change in fuelling, as its hard to see how the fuel in the cylinder will not be burnt. 6) A richer mixture (i.e. more powerful) is needed to accelerate the engine. Bollocks. Running a seriously rich mixture at say 1300RPM/0" vac, does not help the problem. Neither does serious amounts of dMap/dt. dTPS/dt helps a little, but not much. 7) Ram Air effect of the flow coming into the manfold. Perhaps, but hard to see how this will have more than about 10% percent, running that much richer steady state doesn't seem to help. ---------------------- Having stated what I think its not, here's what I think it is: 1) Fueling delays. The ECU not responding to changes in MAP as quickly as the engine. The engine will respond on a cycle by cycle basis, whereas an ECU and MAP sensor most likely will not. 2) The fact that the fuel is injected before the IVO (intake valve open) event, but the engine "samples" MAP at IVO. Therefore it may not be predictable what the fuel will need to be, when the fuel is squirted in, because the MAP can change significantly then and IVO. A carb will also experience delays in fueling, mainly due to distance from the port, so hence the need for the throttle pump. Q. How do TBI system deal with this? Weber DCOEs throttle pumps will squirt seriously far and fast, and these carbs are known for being able to acheive exceptionally good throttle response. SU carbs combat this by momentarily restricting the airflow, thereby bypassing the problem. Plus the excellent vapourisation at low flows, will make the engine more resistant to lean misfire. I've heard rumours of some OEM ECUs, doing multiple injections per revolution to effect their enrichment, based upon dTPS/dt, this would certainly help. Obviously the other idea that may help, it calculating the fuelling and injecting at late as possible in the cycle, i.e. to coincide with the closing of the valve.
