Sorry about the discouraging remarks people posted, despite the fact you stated any _help_ would be appreciated. Come on, people, if you dont know how to do something, dont say it can't be done! anyway.. I myself am working on a project almost exactly like yours, mine being a 1980 suzuki GS1100 four with sixteen valves, basically the same thing as your XS1100 (also air cooled). I'm so sick of my carburetors that i've contemplated catapaulting them into mexico, but my bike is my main transportation so i've decided to wait until i install fuel injection. In the mail right now (should arrive tomorrow) is a complete EFI setup from a '84 volvo 240 with bosch LH-jetronic. The system uses a hot-wire MAF sensor for its primary metering decisions. It uses approximately 17lb/hour fuel injectors which allow the 2.1L volvo engine to produce up to 120 horsepower in production form. they're just right for our needs. The fuel rail has a manifold vacuum referenced pressure regulator at the end, and i intend to cut it where i need to, and bridge the pieces back together in the appropriate spacing for my motorcycle using 1/2" ID fuel hose and hose clamps. I intend to make an intake manifold out of gutted carburetors while I fabricate a more elegant piece out of aluminum. I happen to have access to a nice machine shop with TIG (electrical arc) welders which can weld aluminum, and i'll be making some parts with lathes.. but the same effect could of course be achieved with cut metal tubing and short pieces of radiator hose and hose clamps if you lack those resources. speaking of resources, one of the main reasons i'm going with the LH-jet setup i speak of is because a buddy of mine happened to have it lying around and i'd rather experiment with "what's lying around" than go out and explicitly purchase a setup without knowing if it'll work well. I fully expect this FI setup to operate my motorcycle satisfactorily from the get-go, despite the fact that its breathing characteristics are very different from a tractor-engine-like 8-valve 2.1L volvo engine (which rule, dont get me wrong). One of my ultimate goals for this system include equal or superior drivability and performance to a perfectly tuned carb setup. Since i've never cracked open an LH-jet ECU, i've already come up with a few ways to tweak the system without modifying a thing, in case I can't find solutions within its built-in flexibility. for enrichment on throttle-whacking, i intend to explore various places for the connection to the fuelpressureregulator's vacuum reference. By letting it see an increase in pressure faster than it normally would, pressure in the fuel rail would jump during throttle openings and provide an accelerator-pump effect superimposed on the computers' intentions. I have other ideas like this, but ideas are all they are until i try them. for oxygen sensors, i'll be mounting one at each exhaust port, with bi-color LEDs on my instrument cluster to indicate rich/lean status for each. the ECU will get its info from whichever of the four i tell it to. Of course, when i get the gear on my bench I intend to open it all up and catalog all the chips in everything, and read the prom(s) (assuming there are any!) to see what i can figure out. Volvo EFI setups like this are cheap enough to acquire to make fully reverse-engineering them worthwhile. According to my friend sending it, there are two "boxes" in the system, one is the ECU proper and the other is under the hood with a good number of wires and a vacuum transducer mounted right on it; i suspect this box has a lot to do with the ignition and timing since LH-jetronic does not normally involve itself with that task. That's great, because the ignition system on my bike is fine for the moment and it will be that much easier to tweak the new EFI setup without having to worry about spark. So, rest assured, myself and others on this list are embroiled in the same exact endeavor as yourself, many of us on 1100 fours, of course :) I am quite determined to be running on EFI as soon as possible, and i'll share all of my findings and formulae with the list, and you are more than welcome to simply trace my steps on your own bike if you want to just do it first and then learn. The only factory bike EFI out there people talk about is the kawasaki 1100 which, as i understand, were so strange and crappy that many of them were replaced with carbs!!!

HOWEVER... I'm a little confused as to how to get it to save more than a single frame. I hit the spacebar to do a capture. It seems to come out of "link" mode when it's done capturing... or at least it did on my way to work this morning. Didn't do that last night. Anyhow... do I save at that point? Side note: my ECM plug at the battery pigtail was a little loose. Pushed it in nice and tight yesterday morning and haven't had a miss yet. Of course as soon as I send this message I'll be jinxing myself back into problems :) I'm not getting ANY spark knock recorded, though it is cold this am. I am sure that I'm getting some audible knock though. At least that's what it sounds like to me. Anybody have a test for the knock sensor and/or ESC module handy? I'll look it up at home tonight otherwise. It'll only link with my '165 ECM (TPI, MAF) in ALDL mode, not diagnostic. Is this correct? It doesn't show fan command even when the fan is on. It also shows skip shift... shouldn't have that for this car. I think I'm using Diacom 2.85.

Assuming the "capture-stop after 200 frames" is what you mean, that is normal for standard Diacom. After that, hit for disk, then for save. Then yopu must choose to save BUFFER, not frame. After saving, you can convert to xbase too. BTW If you have Java Runtime Environment installed on your WIN95 PC, you can dowmload Richard Tomlinson's playback program and give it a try. Shows gauges graphically and replays the session from the captured diacom data. Was written for GM Syphoon turbos, but I bet it will work with other stuff To get it or Java Runtime, snoop around www.syty.org look for downloads or something like that.

If this is correct, and I suspect it is, the digital stuff I sent you is probably not appropriate. The slowest crystal oscilator is 1 MHz, which is way too fast for this application. Sure, we could divide the clock down, but now the design is increasing in number of chips. I think the best way to continue is to treat this like a real engineering project. We need to define the input and outputs for both the 2000 and 4000 pulse systems. If you can provide them, I will produce the Phase Locked Loop design that will multiply by 2 and also provide a working design for a divide by 2 circuit. There has been some mention that one of the signals is DC coupled, and one is AC coupled, and I remember reading that one may be sinusoidal. I will need those details, Confirmation of the 56Hz at 100 MPH, the peak to peak levels, and the waveform of each set of signals. As soon as those are provided, the PLL design will only take a few days. Let me know what you think.

Tap on the block or exhaust manifold near the knock sensor and it should register knock. If it doesn't, remove the knock sensor connector and jumper to +12. That should make the ESC module signal knock. If that works the knock sensor is dead. If it doesn't the ESC module is dead.

I don't think I've seen one with a lock range the low. A minor mod to your 30Hz Vats bypass circuit, to up the frequency might work well with the frequency doubler. You're correct, the PLL won't support a 0 Hz input, at least I don't think it will. Although it is possible to design the lock in and track range to be very wide, I don't know what the extremes are. It may be that the digital design with a non"canned" oscillator would be suitable. There are some 32 KHz crystals available and that could be divided down to the 100-200 Hz range fairly easily. My problem is that I don't like RC oscillators when exposed to temperature extremes. Maybe the guy with the PIC should just take care of the issue. It would seem that the PIC would be a simple circuit to build, and very easy to implement. What do you guys think?

The dc bias would require a d/a converter and other such stuff: Version 2! As stated before, starting and stopping are the interesting parts. Acceleration and deceleration at slow speeds also complicate matters. Do I assume the vehicle can change speeds at more than 2G's? There aren't may street machines that can exceed 1.3G.

It would only be one part (not counting power supply parts), plus a jumper to select double or half. I think I like Bruce's original idea the best, though. Two 555s, each in monostable mode, one on the positive edge and one on the negative. That's one IC (556) plus some passive components, plus a couple transistors to combine the outputs. Battery voltage works fine. It also avoids programming the PIC. You won't get a 50% duty cycle at all speeds, but it doesn't sound like that's a problem since the ECM uses a zero crossing detector. --steve -- Steve Ravet steve.ravet@arm.com Advanced Risc Machines, Inc. www.arm.com From diy_efi-owner Thu Oct 1 15:03:55 1998 Return-Path: Received: (from mail@localhost) by esl.eng.ohio-state.edu (8.8.7/8.8.7) id PAA26707 for diy_efi-outgoing; Thu, 1 Oct 1998 15:03:55 -0400 X-Authentication-Warning: esl.eng.ohio-state.edu: mail set sender to owner-diy_efi using -f Received: from accessone.com (root@blaze.accessone.com [198.68.191.19]) by esl.eng.ohio-state.edu (8.8.7/8.8.7) with ESMTP id PAA26703 for ; Thu, 1 Oct 1998 15:03:51 -0400 Received: from seasteel.perkinscoie.com (seasteel.perkinscoie.com [209.168.2.2]) by accessone.com (8.8.5/8.8.5/PIH) with SMTP id MAA18124 for ; Thu, 1 Oct 1998 12:03:44 -0700 (PDT) Received: from seamail.perkinscoie.com by seasteel.perkinscoie.com via smtpd (for mailhost.accessone.com [198.68.191.19]) with SMTP; 1 Oct 1998 19:03:13 UT Received: (private information removed) Message-ID: <7F57DC2D45ADD11196B700A0C99B563201461DF5@seamail.perkinscoie.com> From: "Stowe, Ted-SEA" To: "'diy_efi@efi332.eng.ohio-state.edu'" Subject: RE: diacom ? talking to ECU's Date: Thu, 1 Oct 1998 12:03:01 -0700 MIME-Version: 1.0 X-Mailer: Internet Mail Service (5.5.2232.9) Content-Type: text/plain; charset="iso-8859-1" Sender: owner-diy_efi@efi332.eng.ohio-state.edu Precedence: bulk Reply-To: diy_efi@efi332.eng.ohio-state.edu does a GM 1226867 have any communication capability ?, I have seen threads about talking rs-232 to the units but I never understood how this got accomplished and what this would get me.

Diacom is software that runs on a PC and acts like a scan tool. It listens to the ALDL data stream on GM cars (and some other makes also) and displays it on the screen. Since it's on a PC, it can log a lot more information and has much better displays than a dedicated scan tool, but it requires having a PC in the car and costs more than some of the newer cheaper scan tools. --steve -- Steve Ravet steve.ravet@arm.com Advanced Risc Machines, Inc. www.arm.com From diy_efi-owner Thu Oct 1 15:23:34 1998 Return-Path: Received: (from mail@localhost) by esl.eng.ohio-state.edu (8.8.7/8.8.7) id PAA27109 for diy_efi-outgoing; Thu, 1 Oct 1998 15:23:34 -0400 X-Authentication-Warning: esl.eng.ohio-state.edu: mail set sender to owner-diy_efi using -f Received: from imo17.mx.aol.com (imo17.mx.aol.com [198.81.17.7]) by esl.eng.ohio-state.edu (8.8.7/8.8.7) with ESMTP id PAA27105 for ; Thu, 1 Oct 1998 15:23:33 -0400 From: MrCad472@aol.com Received: from MrCad472@aol.com by imo17.mx.aol.com (IMOv16.10) id 7BYSa10153 for ; Thu, 1 Oct 1998 15:22:40 -0400 (EDT) Message-ID: Date: Thu, 1 Oct 1998 15:22:40 EDT To: diy_efi@efi332.eng.ohio-state.edu Mime-Version: 1.0 Subject: Re: diacom ?

The only thing I worry about is the drift and resulting pulse width change over time and temperature. The design I submitted uses a dual D Flip flop and an exclusive or (XOR) to generate a pulse at each transition (two 14 pin chips, and if 4000 series CMOS is used, it can also use battery voltage). It is just a digital version of Bruce's idea. The only problem is the frequencies are so low that the digital solution will also be forced to use an RC based oscillator. The frequency of the oscillator determines the pulse width. If the ECM uses a zero crossing detector, does that mean all the signals are AC. Also, what is the Peak to Peak Voltage level? Do we have any idea of what minimum pulse width the ECM can detect?

I assumed there would be sensor and wire harness changes. Man, that makes all the difference. There are some things I want to change like the idle settings (too high right now, like 1050 rpm). So I can go get a '747 ECM, and a copy of a prom from a 350 truck, and I'll be set to go? And I can keep the 6965 under the seat for emergency backup? Too cool.

Ted, according to Ludis' homepage, that ECM is a C3 ECM with serial pinout on pin C6. Therefore, it should have the 160 baud ALDL stream. Look in the archives for information about C3 ALDL. It won't connect to the rs-232 port, but you could hook it to the printer port and program a uart in software. With some trickery (described in the archives) you can hook it to the rs232. A regular old scan tool like diacom or a handheld unit should read it also. --steve -- Steve Ravet steve.ravet@arm.com Advanced Risc Machines, Inc. www.arm.com From diy_efi-owner Thu Oct 1 17:18:33 1998 Return-Path: Received: (from mail@localhost) by esl.eng.ohio-state.edu (8.8.7/8.8.7) id RAA30019 for diy_efi-outgoing; Thu, 1 Oct 1998 17:18:33 -0400 X-Authentication-Warning: esl.eng.ohio-state.edu: mail set sender to owner-diy_efi using -f Received: from mtiwmhc01.worldnet.att.net (mtiwmhc01.worldnet.att.net [204.127.131.36]) by esl.eng.ohio-state.edu (8.8.7/8.8.7) with ESMTP id RAA30015 for ; Thu, 1 Oct 1998 17:18:33 -0400 Received: from malinda ([12.69.65.88]) by mtiwmhc01.worldnet.att.net (InterMail v03.02.03 118 118 102) with ESMTP id <19981001211801.JPDT7427@malinda> for ; Thu, 1 Oct 1998 21:18:01 +0000 Message-ID: <3613F403.A74DAEDC@att.net> Date: Thu, 01 Oct 1998 17:28:35 -0400 From: Jason Weir X-Mailer: Mozilla 4.01 [en] (Win95; I) MIME-Version: 1.0 To: diy_efi@efi332.eng.ohio-state.edu Subject: Re: 68HC11 disasm beta X-Priority: 3 (Normal) References: <199810012057.NAA09448@gonzo.wolfenet.com> Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Sender: owner-diy_efi@efi332.eng.ohio-state.edu Precedence: bulk Reply-To: diy_efi@efi332.eng.ohio-state.edu Orin Eman wrote: > > Now that I get it too output is there any way to output to a file or > > > caputre the output??? or is that what "not implemented" meant???

The 555 solution may not be good for driving an electronic speedometer, but even with drift it should be fine for the ECM.

The limiting factor in the days before cheap LSI was memory, especially RAM - Expensive and power-hungry. This was true from vacuum tube computers right on through the '70s. Intel originally developed the 4004 under contract to a Japanese calculator company. Somewhat later they negotiated a license to sell it on their own hook, feeling that its potential use in what are now called microcontroller applications would enhance memory sales (Intel's primary business then).

"Processors" were purpose built at that time (and not all digital). They only included those functions in each computer, that were need for that computer to complete its mission nothing more. Digital Logic was very expencive and used lots of power so any computer(s) on the apollo spacecraft, (Even the shuttle, but they may have upgraded it) would have been special built for the specifc job it was to do, and even by the standards of the 6502 would have been slow, used lots of power, had very little program-data space and not very adaptable to any other use. The Military and NASA was the driving force in the early years of the semiconductor industry, as they wanted to reduce the power used and weight of the rocket guidence systems, they were building crude guidence (by todays standards) computers with lots of transistors and passiive compents. Russia just built bigger rockets. Alot was done using analog computers they used fewer transistors for a given task (Look at the early EFI "computers") but were not very adaptable to other functions.

So you're saying the new IAC I put in is not working correctly? Just want to make sure I'm understanding my problem. I followed the instructions as closely as possible. Checked the plunger extension <1.125" prior to installatation. On the bike (or any engine) - as the only DPFI I have any familiarity with right now is a Saturn, and as I've noticed that the plenum does a couple of nice things 1) houses the PPM, TPI and IAC and provide both ports and mounting points for the actual injectors and 2) these ports are VERY close to the intake port spacing on the engine I'm initially trying to adapt - I was thinking this piece would be a good place to start and would solve a good many of the mechanical problems. I also believe in UFOs so I'm curious what your thoughts on this would be. BTW, very soon I'll be able to scan a pix of this setup so you can see it better (you're probably not familiar - or interested terribly) in Saturn DPFI, ha! The other question you asked (air cooled is yes on my initial project). Inline 4 - which is what a good many of the performance bikes are today, hence important. If I could get a system to work on this type of engine - I could get one to work on a good many bikes (with a large user base that might be interested).

As far as I can tell American cars use a 1000 rev per mile speedo ratio. I know for sure many cable driven speedo GM cars use a speedo mounted VSS generator. This gen consists of a LED and a photo reciever ( diode or a transistor ) mounted in a small plastic holder ( ~1/2 X 1/4" X 3/8") , 12 inches of wire, and a buffer ( Yellow plastic ~ 1" X 1/2" X 3" ) From what I remember it has three connections: 12 VDC in , Ground and Signal Out. The LED / Photo in bolted ( with one small screw ) to the rear of the speedo and looks at the u shaped magnet holder( shiny metal ) that is driven by the speedo cable. So. . . . for each rev of the cable, the LED reflects back twice for every rev. 1000 Revs Per Mile = 2000 Pulses Per Mile Need 4000 per mile? just add two more shiny ears to the magnet holder. Instant 4000 PPM ! :+) Don't have a GM car? With a little work you could add the LED/ buffer to most any car. Just cut a slot and drill a hole. Don't have 1000 rev per mile? Most likely the ECM dosn't care if you have 800 PPM to 1200 PPM.

Liket the other guy said, i just unplugged the 6965 computer and plugged the 747 in. That is all their is to it. The only difference i saw was the 747 doesn't use the MAT sensor. You don't even have to remove the wire for the MAT sensor, because that pin on the computer isn't even used so it doesn't see it at all.

It had 4 - 74181 (4 bit very simple slice proceeor) at its center and a massive pile of 74 and 74H series logic around it. The cooling fan for it used almost as much power as some of the desktop systems we have today (55W), the power for the entire computer (very simple computer) was I believe about 1500W, it generated alot of heat, and it was big, bulky, and probably a very simple computer that was not really useable to run a car or really anything else very complicated. I think the whole computer unit probably weighted 200 lbs as was probably on the same calibar as a 6502 or 68HC11 speed wise. I seem to remeber that it had 16k (an entire board the size of todays motherboards, completely stuffed with memory chips, and addressing logic). It was not really something that would be useable for EFI, especially since the chips that made up the cpu board proabably cost $1+ each, and there were several hundred, maybe into the low thousands that made up what would probably have been an equivalent to the <1Mhz processors that easily fit on a single chip now.

It has started running up (jumps to 2000 2500 rpm when I stop and put the car in neutral or if I stop and put it in park). This is new. Don't know what's changed! I got a Haynes book on Saturn's which has cleared everything up. The fuel injection chapter troubleshooting guide lists (faulty injector, faulty egr, clogged air filter or vacuum leaks) for over half of all possible problems!

I'd like to follow this close! Sounds like a real opportunity to delve in first hand. I'm absolutely green. I don't have any EFI units to "play" with right now. I am trying to fully understand the diy-efi project unit on the web page (very nice) and very well documented. I do have an advantage as I've actually programmed EPROMs before EEPROMS are the same thing only electronically erasable rather than UV. Unfortunately, I don't have the programmer now (different computer system). But that does give me the opportunity to see what others are using and then move in that direction. Seems so far like 68000 and 6502 processors are in front. Unfortunately, thats about all I have with regard to efi right now. Everything else is on a long, long learning curve. I'll be eagerly following your progress.

I dunno much if anything about the processors involved, but can tell you that shuttle technology, (dating back about 13 years, may well have changed since) in order to get the level of reliability deemed suitable, was as follows: For any given set of control functions a total of five identical controllers (sensors and all, I believe) were used (all self-diagnostic, of course). Three were functional, two were back-ups. The three functional ones voted on any given control function. If the three were not unanimous on a control action, (despite a lack of any self-diagnostic admission of a problem) the odd system got thrown out, and replaced with one of the two back-ups, then unanimity was sought again, etc. This info was extracted (gently) from the brains of a couple of Otis Elevator guys with whom I had the pleasure of serving on a code-writing committee for part of a ski-lift and tramway code (ANSI B-77). Their general reaction to what the early fifties vintage tramway guys thought was "Fail-Safe" was laughter (actually guffaws), followed up with a description of how NASA was currently doing things for those of us who wanted to listen. Perhaps there are lessons in this kind of approach for grasshoppers, Princes of Darkness, and other such critters.

Your advise is needed! Now my friend wont make turbo on him BMW540 with boost 2 bar. And hi do not wont change ECU parameters. I offer to him some upgrade to EFI. In parallel to MAF install tree electric-drive throttles T1, T2, T3 and 3 injectors J1,J2,J3 (supplied by own OEM fuel pump and own OEM press. regulator) that fires on OEM throttle every crank rotation with pulse width that OEM ECU determine for standard injectors. F - fuel performance of set (8 unit) of OEM injectors. S - squares of MAF air flow. And (1.26) ^ 3 = 2 P - manifold press. F( i ) - fuel performance of J( i ) Squares of these throttles will be: S(T1) = 1.26S - S = 0.26*S S(T2) = (1.26*1.26)S - S - S(T1) = 0.33*S S(T3) = 2*S - S - S(T1) - S(T2) = 0.41*S F(J1) = 0.26*F F(J2) = 0.33*F F(J3) = 0.41*F J(i) may be one injector or group of injectors for getting calculated fuel requirement. T1 open when P = 1.15 bar off when P=1.11 bar T2 P = 1.45 P=1.39 T3 P = 1.82 P=1.75 J(i) fires when T(i) is open. Thus on idle, cruse or when P < 1.15 bar EFI works as standard one. But when boost grow fuel supplement grow up too but ECU not «think» that MAF signal too high for these throttle position and rpm. Example: on boost P=2 bar and WOT, air flow throw MAF will be: 2*(standart flow), and 0.5 will flowing throw MAF and 0.5 flowing throw T1,T2,T3 because S(MAF) = S(T1)+S(T2)+S(T3); And fuel quantity will be: 2*(standard fuel flow) because all J(i) will be working. And ECU will obtaining signals as in OEM system without turbo. Number of addition throttles may be high (4,5,....), but in case 3 add. throttles maximum mistake of MAF signal will < 12....15 %. What you think about it. Did you hear about system look likes it. Your opinion very important for me and my friend!

They are CRJ3869, DJU4085, HDU0552, HDW0557, HTD5293, and HTL4811. Ted already has the DJU. The HDU and HDW are from 1985 2.0's, the HTD is from an '86. I didn't keep track of any more info. The 1985/86 2.0 J-cars are flooding the junkyards, at least around here. A few hours spent wandering around should yield a PROM from a manual car. Bring a 10mm box wrench, a 7mm socket, a 1/4 inch socket, and a flat screwdriver/prying device. The J-cars should have one of three transaxles: the GM "Muncie" 4 speed manual, the Isuzu 5 speed manual, or the THM125 3 speed auto. Most will probably have the auto. The quickest way to identify (and skip) the autos is to look into the engine bay at the driver's side. The THM125 has an "oil pan" on the end/side. If you see shiny stamped steel, it is an auto, and time to move on. Steve Ravet wrote: > Ted, according to Ludis' homepage, that ECM is a C3 ECM with serial > pinout on pin C6. Therefore, it should have the 160 baud ALDL stream. The C6 pin is where the mask ROM dumper sends it's output. That's normally an IAC output. The 160 baud ALDL output should be on pin A8, just like a 1227747.

Do we have any idea of what > minimum pulse width the ECM can detect? Many C3 ECMs, like the 1226870 and 1227148, use a timer chip (TPU?) marked 16023263. One of its functions is to measure the VSS pulse interval. The 16023263 records the time of the pulse's rising edge. Because the ECM input buffer also inverts, this is the falling edge of the 12 volt DC 2000 ppm VSS input to the ECM. Software takes the difference between two samples to compute the interval. The 16023263 measures in units of 65517 3/16 Hz. The VSS sampling appears to be delayed by 90 of these clocks. This may be an internal TPU latency, or a delay to "debounce" the signal. So, 90 / 65517 is about 1.37 mS. The 90 cycles might include a computational delay in a (unrelated) PWM output. More O'scope work is needed... Newer ECMs might not have exactly 1.37 mS of delay, but that should be in the ballpark of the minimum pulse width. -- Ludis Langens ludis (at) cruzers (dot) com Mac, Fiero, & engine controller goodies: http://www.cruzers.com/~ludis/ From diy_efi-owner Fri Oct 2 06:18:26 1998 Return-Path: Received: (from mail@localhost) by esl.eng.ohio-state.edu (8.8.7/8.8.7) id GAA09030 for diy_efi-outgoing; Fri, 2 Oct 1998 06:18:26 -0400 X-Authentication-Warning: esl.eng.ohio-state.edu: mail set sender to owner-diy_efi using -f Received: from tucows.dockside.co.za (tucows.dockside.co.za [196.25.199.6]) by esl.eng.ohio-state.edu (8.8.7/8.8.7) with ESMTP id GAA09026 for ; Fri, 2 Oct 1998 06:18:17 -0400 Received: from ccii.dockside.co.za (root@ccii.dockside.co.za [196.25.199.201]) by tucows.dockside.co.za (8.8.8/8.8.8) with ESMTP id MAA18265 for ; Fri, 2 Oct 1998 12:22:11 +0200 (SAST) (envelope-from wrm@ccii.co.za) Received: from ricebox (ricebox.ccii.net [192.168.1.20]) by ccii.dockside.co.za (8.9.1/8.9.1) with SMTP id MAA32311 for ; Fri, 2 Oct 1998 12:34:11 +0200 Message-Id: <199810021034.MAA32311@ccii.dockside.co.za> X-Sender: wrm@192.168.0.1 X-Mailer: Windows Eudora Version 1.4.3 Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Date: Fri, 02 Oct 1998 12:06:01 +0200 To: diy_efi@esl.eng.ohio-state.edu From: wrm@ccii.co.za (Wouter de Waal) Subject: Re: 6502 chip, HC11 disasm Sender: owner-diy_efi@efi332.eng.ohio-state.edu Precedence: bulk Reply-To: diy_efi@efi332.eng.ohio-state.edu Hi Orin & all >Hmm. I put a small program thru which I had the asm source for and didn't >notice anything. What Motorola documentation is wrong? I have a 2.9MB file, HC11RM.PDF, which I downloaded from somewhere. The title page sez M68HC11 reference manual, Rev 3, (c) Motorola 1996. (510 pages!) One example: on page A13, the ASR instruction the table reads (in part) CYCLE ASRA(IMM) ASRB(DIR) ASR(EXT) ASR(IND,X) ASR(IND,Y) 1 OP 47 1 OP 57 1 OP 77 1 OP 67 1 OP 18 1 2 OP+1 -- 1 OP+1 -- 1 OP+1 hh 1 OP+1 ff 1 OP+1 68 1 Now, the first 2 entries should be ASRA(IMM) and ASRB(IMM), but most of the instructions operate on one register only, and the second column contains the opcode for the DIR mode. That's what I mean by "cut&paste error". It occurs in quite a few places, also in at least one place the numerical opcode value is wrong, and conflicts with another opcode. I guessed which one was correct, based on the similarity (normally IMM, DIR, IND,X, EXT are nx, (n+1)x, (n+2)x and (n+3)x, or at least that's the pattern I noticed. For example, the IND,Y instruction above, compare it with ASL(IND,Y) which is 18, 68. ASLA is 48, so I would assume that ASR(IND,Y) should be 18 67 to match the n7 pattern for ASR. You see? I looked for a table with one error, and the first one I find, has two errors! :-) That's why I would like comments on whether my disassembler is disassembling (dissembling?) correctly...

One thing I have discovered (or a couple of things actually) is 1) if I hold my foot on the throttle to maintain 1000 rpm the car doesn't die - there's a revelation! but I will get little bumps, like misses but stiffer (harder feeling). They seem to come about 1/3-5 sec and 2) this will sounds stupid but the oil pressure gauge needle spikes (heads for max pressure) just before I feel the bump! Now I do see those oil pressure spikes occassionally and don't feel the bump too. I do not see any of this if 1) I'm accelerating to the point of being in passing gear, 2) my foot in completely off the gas (coasting). If it could just be a little wierder!

Remember, by '91 there weren't many TBI V8s in cars at all. In fact, I'm not sure what car would have had a TBI V8 besides the Caprice. By the way, Ludis, I just called a local dealer parts supply, and the '91 Caprice w/305 uses the 6965, same as '91 w/350. You've got those marked unknown ('91-'93 5.0 V8 TBI vin "E"). My guess is the 4.3 V6 TBI "Z" is also 6965, but I didn't confirm that.

Meaning the dealer can discount or make up, anyway they want. Lots, of dealers used to use normal list X 2. That is why they have such a reputation for price gouging. Lots of parts folks, would rather sell 1/2 as much at twice the mark up. It seems to be changing a little, but it's a slow change. One other factor about pricing is that often the part/service departments pay the overhead for the entire store, so that all the new/used car sales are profit. Makes for easy book keeping. So if your ever going to need genuine brand x parts take the parts manager to lunch or something, Before ya need a favor. Then don't abuse things, ie if you get a discount find out if it's OK to pass along. Like I can get a good price when I order stuff that can get placed on a stock order, but that means I might wait 30-40 days for it. Otherwise, I pay normal list. Or if doing a big buy, I get a good price, but I tell the parts guy what the deal is. Then the local parts house owner happens to like having his pulling tractor run right, and I help him. So there are good prices to be had, but the more actively you pursue them, the better they get. Just my .000002 cents worth.

One of my duties was to dive it around all day for mileage accumulation, of course i would stop at various party houses or pick up hitch hikers to turn them on. In grey-market days we would drive rolls royces to lab, we had long hair, so when make a stop would turn on the teeny boppers by impersonating rock stars.

It will be as an attachment. I changed computers and this is like a 1/2 jillion hours and I'm not retyping it again. So this reviews what has been covered in 808 to date, and some new items. The explainations/definitions will be forth coming, but the little guys ain't much for typing. Again this is for educational purposes, and learning about engine management and the basic understanding of the tables switches settings relevant to them. The attachment is of a ASBX, that was used in the australian 808 ecm. The titles across the top are for 4 cylinder turbo, 4 cylinder NA, v-6, and v-8. This way you can read the related area and how the calibrate varies for different combinations. Note this is for a one bar map application, and the turbo 4 just uses a 2 bar map, and runs the 1bar code, without the proper corrections. In an application where Bar corrections are used this would have driveability, and malfunction flag problems. But, this would appear to be a "poor man's" racing application. Is it perfect, no. Is it close I beleive so. Some of the items have been run on the bench and seem right. The user accepts all resonsibility for using this information. It may be illegal for you to use this information on a public highway, and if not then also should be done with adult supervision.

It is 3.75 stroke by 4.155 bore which figures out to about 306 C.I. . The heads are aluminum bow tie with big valves . I have set up the compression to be 7.5 so that I could turbo it . I will most likely put it in a light weight kit car . The question is this : What type of injection would work the best ? CIS , TBI . Electronic Sequential Port Injection or what ?

The result ($0253) is used as an index for *alot* of table lookups. Is this the speed density equation? Is it calculating airflow? That's the only thing it seems like it could be doing. If so, is it in grams/sec? BTW: I've figured out that the IRQ interrupt is triggered by reference pulses. It sets up TOC1 to occur 1.67 ms later. TOC1 then reads the ESC monitor, finds the difference in spark control counts, then adjusts the result according to RPM.

I believe they featured the 3M one on Shade Tree Mechanic. There may be a problem with getting the correct fittings. Along similar lines, I just bought a fuel pressure tester from JC Whitneys that supposedly is for Bosch K-jetronic CIS systems.. However, there is no adapter for the toyota fittings (5MGE) which uses the through bolt with hole and copper washer setup. I'd also like to use it one my Volvo but that uses a metric compression fitting that doesn't work either with any of the adapters provided. My question is, does anyone know a source of metric to larger metric compression fittings or metric to perhaps a barbed fitting that could be used with a piece of fuel hose and a clamp.

I've you've ever uploaded a file to the ftp site, it'd save me some time if you could send me a description of it.

I just instaled an aftermarket ignition system on my two rotor engine (13b). One of the installation steps was to configure the system for the number of cylinders. It needs this information because it will change its behavior above 3k RPMs. The only input that it has it the trigger to the coil. In order to decide how to set it, I decided that I needed to figure out how the Sparks/revolution (crank or eccentric shaft) compared between the two engines. the numbers that I came up with don't make sense and I am hoping that someone can tell me where my logic has failed me. I am under the assumption that in a piston engine, each cylinder will fire once for every two revolutions of the crank shaft. I am also under the assumption that in a rotary engine, the leading plug (and trailing short afterwards) will fire twice for every three revolutions of the eccentric shaft. Yet another assumtion is that both rotors fire at exactly the same time. I have come to this conclusion by the fact that I have one coild with two leads for the leading plugs. There is one trigger for the coil and no distributor. Given my assumptions, a coil on a piston engine (assuming one coil for all cylinders) will have spark / minute = RPM * Cylinders * 0.5 According to the formula above the table below shows the number of sparks per minute for 4, 6, and 8 cylinder engines. 4 cyl 6000 RPM 12000 SPM 6 cyl 6000 RPM 18000 SPM 8 cyl 6000 RPM 24000 SPM Given my assumptions for the rotary engine the table below should describe the saprks per minute for 1 and 2 rotor engines. 1 rotor 6000 RPM 4000 SPM 2 rotor 6000 RPM 8000 SPM Since one trigger pulse will fire both rotors, the aftermarket ignition system will only see 4000 pulses per minute at 6000 RPM. I think this is equiv to a 4 cyl piston engine running at 3000 RPM. Have I made a mistake in my calculations?????? -Quinton mailto:quintonm@bellsouth.net ===8<===========End of original message text=========== -Quinton mailto:quintonm@bellsouth.net From diy_efi-owner Mon Oct 5 18:20:35 1998 Return-Path: Received: (from mail@localhost) by esl.eng.ohio-state.edu (8.8.7/8.8.7) id SAA26537 for diy_efi-outgoing; Mon, 5 Oct 1998 18:20:35 -0400 X-Authentication-Warning: esl.eng.ohio-state.edu: mail set sender to owner-diy_efi using -f Received: from ar.ar.com.au (root@ar.ar.com.au [203.18.148.1]) by esl.eng.ohio-state.edu (8.8.7/8.8.7) with ESMTP id SAA26533 for ; Mon, 5 Oct 1998 18:20:32 -0400 Received: from kojab.ar.com.au (dialup154.ar.com.au [203.18.148.154]) by ar.ar.com.au (8.9.1/8.9.1/AR-1.1) with SMTP id IAA20057 for ; Tue, 6 Oct 1998 08:25:48 +1000 Message-ID: <3619385B.1DB6@ar.com.au> Date: Tue, 06 Oct 1998 08:21:31 +1100 From: Richard Wakeling X-Mailer: Mozilla 3.0 (Win95; I) MIME-Version: 1.0 To: diy_efi@efi332.eng.ohio-state.edu Subject: Re: miss still happening References: <01BDECA4.A8CADA20.dzorde@soanar.com.au> Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Sender: owner-diy_efi@efi332.eng.ohio-state.edu Precedence: bulk Reply-To: diy_efi@efi332.eng.ohio-state.edu Hi Dan, Your missing problem reminds me of a miss I had with an 88 corvette. Is your ignition coil sitting on top of the distributor cap. If it is check the rotor very carefully for burns or tracking. The one I had was tracking down through the cap and rotor causing it to miss. I was told later is was a common prob. Solution was repl rotor and cap if damaged and mount the ign coil away from the cap. Cheers Richard.

TPS also falls into the mix. An electric drill, and sheetmetal screw can be used to defeat a IAC plug. Careful use of an ice pick with a hammer can work.

Already checked everything despite it all being almost brand new. So when it came down to it I tried shifting the leads as they were quite close to each other. It definitely reduced the problem, so I figured it may be worth trying a new set of bigger leads.

However, my truck only uses one of them. I have located the unused Injector "B" output on the PCM, and I'm pretty sure I can alter the PWM of this injector independently of Injector "A". All I want to know is if anyone has already done this? This is just too cool having an already built-in additional injector controller! This could solve any problem I might have with the stock CPI injector being too small to support a turbo. -Mike ========================================== Mike Pitts Delray Beach, FL mpitts@emi.net http://www.emi.net/~mpitts/mike.htm ========================================== From diy_efi-owner Tue Oct 6 00:35:51 1998 Return-Path: Received: (from mail@localhost) by esl.eng.ohio-state.edu (8.8.7/8.8.7) id AAA30749 for diy_efi-outgoing; Tue, 6 Oct 1998 00:35:51 -0400 X-Authentication-Warning: esl.eng.ohio-state.edu: mail set sender to owner-diy_efi using -f Received: from sparticus.bright.net (sparticus.bright.net [205.212.123.14]) by esl.eng.ohio-state.edu (8.8.7/8.8.7) with ESMTP id AAA30745 for ; Tue, 6 Oct 1998 00:35:49 -0400 Received: from nacelp (dark-cas2-cs-50.dial.bright.net [209.143.25.119]) by sparticus.bright.net (8.9.0.Beta3/8.9.0.FNG_Build) with SMTP id AAA21824 for ; Tue, 6 Oct 1998 00:35:46 -0400 (EDT) Message-ID: <000c01bdf0e3$3c7cdba0$77198fd1@nacelp> From: "Bruce Plecan" To: Subject: Re: Additonal injectors on '8625 Date: Tue, 6 Oct 1998 00:38:58 -0400 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 4.72.3155.0 X-MimeOLE: Produced By Microsoft MimeOLE V4.72.3155.0 Sender: owner-diy_efi@efi332.eng.ohio-state.edu Precedence: bulk Reply-To: diy_efi@efi332.eng.ohio-state.edu -----Original Message----- From: Mike Pitts To: diy_efi@efi332.eng.ohio-state.edu Date: Tuesday, October 06, 1998 12:28 AM Subject: Additonal injectors on '8625 >Hi, >Pretty sure of the response I'll get on this one (none), but I'll >try anyway. :) >On my turbo project truck, the stock PCM has two injector >outputs.

Further: I think the twin-rotor machine make use of the wasted spark principle. = (You said a single could feed the primary plug of both the rotors). Thus = the final pulse count would result to 2 sparks per crankshaft = revolution. (The assumption is made that the excentricy of the lobes of = the shaft is 180degrees out of phase). This would then result in two = power pulses per revolution of the crankshaft, which is equivalent to a = 4-cylinder machine. PS. Any other comments, maybe this is wrong? Carlo -----Original Message----- From: Quinton McCombs [SMTP:quintonm@bellsouth.net] Sent: Monday, October 05, 1998 11:34 PM To: diy_efi@efi332.eng.ohio-state.edu Cc: david@rx-7.net Subject: Coil spark rate or rotary vs piston engine First of all, let me appologize for starting another thread concerning how often a rotary engine fires.... I just instaled an aftermarket ignition system on my two rotor engine (13b). One of the installation steps was to configure the system for the number of cylinders. It needs this information because it will change its behavior above 3k RPMs. The only input that it has it the trigger to the coil. In order to decide how to set it, I decided that I needed to figure out how the Sparks/revolution (crank or eccentric shaft) compared between the two engines. the numbers that I came up with don't make sense and I am hoping that someone can tell me where my logic has failed me. I am under the assumption that in a piston engine, each cylinder will fire once for every two revolutions of the crank shaft. I am also under the assumption that in a rotary engine, the leading plug (and trailing short afterwards) will fire twice for every three revolutions of the eccentric shaft. Yet another assumtion is that both rotors fire at exactly the same time. I have come to this conclusion by the fact that I have one coild with two leads for the leading plugs. There is one trigger for the coil and no distributor. Given my assumptions, a coil on a piston engine (assuming one coil for all cylinders) will have spark / minute =3D RPM * Cylinders * 0.5 According to the formula above the table below shows the number of sparks per minute for 4, 6, and 8 cylinder engines. 4 cyl 6000 RPM 12000 SPM 6 cyl 6000 RPM 18000 SPM 8 cyl 6000 RPM 24000 SPM Given my assumptions for the rotary engine the table below should describe the saprks per minute for 1 and 2 rotor engines. 1 rotor 6000 RPM 4000 SPM 2 rotor 6000 RPM 8000 SPM Since one trigger pulse will fire both rotors, the aftermarket ignition system will only see 4000 pulses per minute at 6000 RPM. I think this is equiv to a 4 cyl piston engine running at 3000 RPM. Have I made a mistake in my calculations?????? -Quinton mailto:quintonm@bellsouth.net =3D=3D=3D8<=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3DEnd of original message = text=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

If you have a gold colored Idle plug with a small protruding point you will need to do the following to remove it. 1. Grind the tip off. This is a surfaced hardened plug that will resist the best of the drill bits. 2. center punch the new flat surface and drill a 1/8" hole. BE WARNED! This plug is hardened at the other end also and will "grab" the bit as you drill. This can lead to broken off bits and other scary stuff. 3. Insert sheetmetal screw into new hole and tighten. 4. Using 2 needle nose pliers, PRY the offending plug from it's home. Done this on just about every Howell EFI conversion I've done up here in Colorado. Good luck!!

The IDC connector is a wirewrap socket (long legs) and you can bend wide enough to plug into the eprom programmer, so I have just been leaving that in the programmer, and pluggine the memcal into that. You have to be a bit careful when pluggin it in and out to make sure not to pull the IDC wire wrap pins out of the eprom programmer, but other than that it works great. I used a dremel to make the needed modifications. I checked several of the supply houses (JDR, Jameco, and Digi-key) and none of them had any 66 pin ones.

You should be able to find a 80 pin and cut it as req. We got Electrosonics out here.

Just get a IDE PC board header and bend the long pins to fit your zero insertion plug. The other side will fit the appropriate pins on youd Memcal connector. Nothing fancy, but, I have been doing it like this for years. Remember, you don't have to use all the pins, just the ones that connect to the EPROM.
