This is my first post. I was looking through the archives about additional injector controllers, since I was curious about building one for my 1991 MR2 Turbo. I was thinking about using a couple LM1949 chips from National Semiconductor. These neato little guys take a duty cycle signal and drive an injector (using a trans ofcoarse). What do anyone thinking about using a voltage to frequency converter to convert the boost signal from a pressure sensor to a freq. that the LM1949 could use. As boost increases the duty cycle would increase and hence more fuel squirted. Thughts? Is this how a V-F converter works? Thanks!

Dave, Red does sell a chip that turns on the SES light at whatever RPM you want. It is used for a manual 2-3 shift with the torque converter locked, since letting it shift by it's self with the converter locked up gives sort of a double shift, and slows the car down. He's been offering this option for over a year. I wish I had a copy of it to look at the code patch he used to do it. Prolly a easy code patch for most of ya'll.. BTW, Red was one of the guest speakers at the Turbo Regal tech session at the Nats last week. It was a blast to listen to Red ramble on about anything and everything about making a Turbo Buick fast. BTW.. not really EFI related, but a bit from the pits.. I picked up a Precision Vigilante 9.5" -0- pump stall torque converter at the nats.. ($1150.00 list) Just slapped my tranny back in the car today after my 400 run freshening. Can't wait to hit the drag strip next friday night.. Kinda hard to tell, but seat-o-the-pants dyno checks A-ok! It just dusted a 300ZX with ease on the street with the air on, if that's any indication. It feels good, fo sure.

Come on. All the really >fast cars are automatics, you telling me they don't use shift lights or >tachs when they race? The only problem I see with a shift light in the GN is the TH200-4R trans is slow to respond to the manual shifter... I had a $2500.00 Mike Kurtz top-of the line racing trans in mine, and in 2, D or OD it would shift by itself between 5000 and 5100... If I held it in low and popped it in to 2nd at 5000, it would wait until almost 5600 before it shifted. Waiting till 5500 and it would hit the rev limiter and bounce off it once or twice before it shifted. Mike said the TH200-4R was a great trans, but the hydraulics were a bit slow even after the mods. Now a really built GN with a TH400 or a powerglide, it would probably be a great item, but by the time anyone went to a 'glide or TH400 they were probably at the power level that the stock ECM was long gone =========================================================== David Cooley N5XMT Internet: N5XMT@bellsouth.net Packet: N5XMT@KQ4LO.#INT.NC.USA.NA T.A.P.R.

Background: I've completed a SD to MAF conversion on a 1986 Ford 2.9L EEC-IV truck. Included with the swap was a MAF meter from a 5/0L Mustang (55mm vs the stock 45mm), and 19lb injectors (vs. the 14lb stock, both high impedance). Now I'm trying to fine tune the air/fuel mixture and solve some occasional pining (probably sounds familiar to all of you). Here are my questions (sorry if they are so basic) - 1. Does the EEC-IV system learn in WOT -- that is learn enough to adjust optimal air/fuel ratios? 2. If you adjust fuel pressure to optimize part throttle, will it adapt around it? If yes, could you adjust fuel pressure to optimize WOT only, and then let the computer optimize for the closed loop conditions? 3. For the larger MAF Meter and fuel injectors, can an aftermaket chip (on the diagnostic port) really tell the computer these have changed and correct the tables accurately throughout the full range? 4. MAF Calibration: Does changing the output voltage really work fro street cars? It seems to me that if you just change MAF meter to a larger one, and optimize the output voltage for idle (by adjuster or new resistance) to 0.8v, that this new MAF meter still may not tell the computer the right airflow info at high flow rates (due to different slope or characteristic curves of different sized MAF meters). 5. Why does Ford have two different calibration codes for the same part number MAF meter (used in two different applications)? 6. How do you correlate O2 readings to air/fuel values? 7. How do you re-adjust the advance curves (I want more at WOT and less at part throttle acceleration). How do you know how much? 8. How hard is it for the chip programmers to get all this right? (assuming I give them detailed info) 9. What questions should I ask a chip reprogrammer about what he has done? Many thanks for your help!

What are the communications parameters, i.e. data bits, stop bits, parity, etc. 2. Does anyone know how to decode the data into useful information? 3. 160 bps is not a com port option on the menu. Can I just type it in and it work? 4. Is there a handshake that must occur when initializing communication, or do I just plug it in and start receiving? 5.

Back a couple of years ago, I offered free copies of my 68HC11 code-seeking disassembler (since GM uses Motorola processors almost exclusively) and have had many people request a copy... At that time, I had no instruction manual written... Recently, I've finished the manual and have posted a new ZIP of the disassembler on my website for all to download, along with some Motorola documents... Soon I'll also have Alan Baldwin's AS6811 assembler (the assembler my disassembler was targetted for) online as well... I am also working on writing several new versions of the disassembler to overcome the limitations of this DOS 16-bit version... Those will be posted when they become available... You can read about those versions on my site... To download the disassembler goto: http://home.midsouth.rr.com/dewtronics (all lowercase) Once there, goto the downloads page... There will be a link for downloading the disassembler... The link will take you directly to my machine where I have the file (we have dynamic IP's so you must go through this front-end)... Because of the IP's, you can bookmark the front-end page on midsouth.rr.com, but don't bookmark anything on my machine directly, as they will be invalidated when our IP's change... ... If you have problems contacting the machine, try later -- RoadRunner cable modems have problems quite often (usually a major crash once every 2-3 weeks!)... I also ask that you fill out the online form to "register" -- I enjoy tracking where my programs go -- so far this one is in over 12 different countries! ... You don't have to register if you don't want to, but I would prefer it and any information submitted will be kept completely confidential... You can also "vote" for versions that don't exist yet to help determine which versions should have top priority... While there, feel free to browse the rest of the site -- though much of the site is still under heavy construction and is very incomplete... Enjoy...

If you look through the archives, I suggested a method that might allow your standard serial port UART to receive ALDL data. It involves setting the data rate to something in the 2000 baud to 3000 baud range. You will receive one _byte_ for each ALDL _bit_. You then get to extract the data stream from these bytes via software. > If anyone can answer the following questions, I would greatly appreciate it: Check this out: http://www.isthq.com/~dan/aldl.htm -- Ludis Langens ludis (at) cruzers (dot) com Mac, Fiero, & engine controller goodies: http://www.cruzers.com/~ludis/ From diy_efi-owner Thu Jul 8 20:16:36 1999 Return-Path: Received: (from root@localhost) by esl.eng.ohio-state.edu (8.9.3/8.9.3) id UAA12279 for diy_efi-outgoing; Thu, 8 Jul 1999 20:16:36 -0400 Received: from mailext04.compaq.com (mailext04.compaq.com [207.18.199.42]) by esl.eng.ohio-state.edu (8.9.3/8.9.3) with SMTP id UAA12274 for ; Thu, 8 Jul 1999 20:16:34 -0400 Received: from mailext04.compaq.com by mailext04.compaq.com via smail with esmtp id for ; Thu, 8 Jul 99 19:16:29 -0500 (CDT) (/\##/\ Smail3.1.30.16 #30.10 built 27-oct-98) Received: from mail.compaq.com([not looked up]) (peer mailint12.compaq.com[207.18.199.190]) by mailext04.compaq.com with SMTP id rcv009763; Thu, 8 Jul 1999 19:16:24 -0500 (CDT) Received: from mailint11.im.hou.compaq.com by mail.compaq.com via smail with esmtp id for ; Thu, 8 Jul 99 19:16:16 -0500 (CDT) (/\##/\ Smail3.1.30.16 #30.12 built 25-jun-99) Received: from exccup-gh01.mis.tandem.com([not looked up]) (peer exccup-gh01.mis.tandem.com[130.252.226.241]) by mailint12.im.hou.compaq.com with ESMTP id rcv026556; Thu, 8 Jul 1999 19:16:13 -0500 (CDT) Received: by exccup-gh01.mis.tandem.com with Internet Mail Service (5.5.2559.0) id <339R9YGP>; Thu, 8 Jul 1999 17:16:12 -0700 Message-ID: <2BAEE918EF6CD1118FA800805F57F12E0465643F@excaus-11601.austx.tandem.com> From: "Stegbauer, Michael" To: "'diy_efi@efi332.eng.ohio-state.edu'" Subject: C.E. as shift light Date: Thu, 8 Jul 1999 17:16:09 -0700 MIME-Version: 1.0 X-Mailer: Internet Mail Service (5.5.2559.0) Content-Type: text/plain; charset="iso-8859-1" Sender: owner-diy_efi@esl.eng.ohio-state.edu Precedence: bulk Reply-To: diy_efi@efi332.eng.ohio-state.edu Sorry for the late entry into this thread...

At the local GM training center they have a "black box" that can be used to reflash a PCM off the car, if it happens to lose communication with the scan tool while flashing and goes into permanent dead mode.

Specifically, I'm trying to replace the stock Bosch VAF meter in a Merkur XR4Ti (2.3L Ford Turbo) with the MAF (AMM in Saab verbiage) meter from a '86 Saab 900T (16v 2.0L Turbo). My initial thoughts were that I might get lucky and have a plug-n-play swap (with a little electrical work) since the intake consumptions are fairly close. Even though the Saab MAF has an adjustment screw (What specifically does it adjust?), now I'm thinking this is still not likely since I'm hearing the output curves are different between a MAF and VAF. But before I get that far, I still need to define the 6 circuits on the MAF, and their input/output ranges. I have the schematic, but it only tells me where everything goes. The 4 circuits that route to the PCM (LH Jetronic) are still a question mark. If I had the whole running car (rather than just the MAF), I'd figure it all out in 30 minutes. Anyone care to comment or provide some insight?

Brad, If I'm correct, the MAF from the SAAB is a vane air meter (a spring loaded door that swings and turns a pot in relation to the volume of air coming in.). The adjustment is the spring tension on the door. This air meter isn't going to be any plug and play, as it will add a restriction to the intake, more so than the stock MAF, and may be more of a bear to get working than it's worth.

Even though the Saab MAF has an adjustment screw (What specifically does it adjust?), now I'm thinking this is still not likely since I'm hearing the output curves are different between a MAF and VAF. >> The screw is for idle airflow signal output adjustment. You attach a dwell meter to a connector that goes to the SAAB fuel controller and adjust for a 50% dwell.

I have a bunch of 1.9 liter ecm's from the Ford Escort. It also use's a VAF meter to measure the air entering the engine. The problem in switching to a MAF meter is it measuring the mass of the air (temperature and volume in one signal) where a VAF measures volume and temperature ( and volume are separate signals) then ecm calculates the mass of the air. If someone wanted to use a MAF meter in place of a VAF you would have to build a circuit that removes or separates the air temperature part of the mass measurement output by the MAF meter. This isn't that hard to do. The problem is that a MAF meter's output is almost linear where a VAF meter's output is logarithmic. A VAF meter is very good at measuring a small air flow. The circuit that converts mass to volume would have to take this into account. I'm not an expert on op-amp circuits so I run out of knowledge when I got to this part of the circuit. I think you could create a series of curves with different slopes and create a response curve that is very close to the logarithmic output of the VAF meter. Maybe someone else in the group could help out. If you don't want to built your own circuit to do the conversion a company by the name Split Second has a device that does the it for you. http://www.splitsec.com/ A friend purchased one for his 2.2 Ford Probe but had a hell of a time getting it to work smoothly.

At that time almost all of the cars ran on alcohol, and I don't mean Gasohol(15% alcohol, 85% Gas), I mean pure alcohol. Is this still true. Does your VW run on alcohol, not gasoline? It sounds like the conversion of the engine to alcohol really changed the electronics.

I have learned that it is 160bps and that a 10k resistor between the A and B terminals will put the ecm into diagnostics mode. I would like to write a program that I would share with everyone to analyze oem systems in the field. If anyone can answer the following questions, I would greatly appreciate it: 1. What are the communications parameters, i.e. data bits, stop bits, parity, etc. 2. Does anyone know how to decode the data into useful information? 3. 160 bps is not a com port option on the menu. Can I just type it in and it work? 4. Is there a handshake that must occur when initializing communication, or do I just plug it in and start receiving? 5.

I was attempting to copy a calibration last week, and was having problems with the files coming up with zeros in all locations. After several attempts, and much double and triplechecking various items, I decided it was the memcal. Some investigation, and handy work with a pick and razor blade revealed that the programmer had clipped pin 28 of the 27256 chip. A small pin completed the open circuit, but now I couldn't get a read that would verify. More investigation revealed another clipped pin, I believe # 14. There's a pinout here: http://www.twinight.org/chipdir/giicm/27256.txt which shows the pins as VCC and GND. What is VCC Am I remembering incorrectly about the GND pin being clipped? (they were cross corner, top right and lower left of chip) Is there a brief way to explain why this worked, and how the chip was still able to work in the ecm?

I have now posted the latest version (2.1) of Alan Baldwin's 6811 Assembler. This is the assembler that my disassembler was targetted for. I haven't had a chance to check and verify his new version yet, so I also posted version 1.5 which I have used extensively. The source code is also included! You will also be interested to know that this assembler package contains much more than just the AS6811 assembler. It contains assemblers for the 6500, 6800, 6801, 6804, 6805, 6808, 6809, 6811, 6812, 6816, 8051, 8085, Z80, and H8. And, his latest version (version 2.1) contains ports to Linux!! YEAH! Do NOT confuse this assembler with the AS11 Motorola Freeware Assembler! To download the assembler, simply goto: http://home.midsouth.rr.com/dewtronics/download.html and click the link to enter the M6811 Disassembler Project Page. There, you'll find a link to the AS6811 Download Page. Sorry to have to make you follow so many links, but because my ISP dynamically assigns IP's, which can change anytime, I can't register my domain and I can't give a direct link to the exact page. Also, if the server doesn't respond, please try again -- the RoadRunner cable modem service goes down very often (major crash about every 2-3 weeks). Enjoy!

Why can't a gm ecu such as a 16159278, P4 TPI, be reprogrammed with a haltech or other aftermarket program so that you can have real time tuning capability? Is't the hardware already there? Can you dump the factory programing and reinstall? Would an aftermarket program work? Can't a serial port be added for the laptop? Would the aldl connector work as the serial port? Could this be economically feasable? There are alot of gm ecu's out there sure is a shame to let them go to waste. What are the most significant problems to accomplish this goal? Would it work?

LOL. Anyway, the pins were definitely clipped by the chip tuner. Was the pinout at the url in the original post correct? I could have the pin locations wrong, but I'm sure that they were on the upper right and lower left of the chip, with the notch pointed up. Once I added some "jumpers" to replace the cut pins, I was able to read the calibration. Subsequent reprogramming of another chip with that file worked fine, and the clipped chip worked perfectly when re-installed. Next time I'll take better notes.

I'll get a picture up on the web as soon as I can borrow a digital camera. john gwynne >> From diy_efi-owner Wed Jul 21 10:32:31 1999 Return-Path: Received: (from root@localhost) by esl.eng.ohio-state.edu (8.9.3/8.9.3) id KAA19724 for diy_efi-outgoing; Wed, 21 Jul 1999 10:32:31 -0400 Received: from claire.a2000.nl (claire.a2000.nl [62.108.1.21]) by esl.eng.ohio-state.edu (8.9.3/8.9.3) with ESMTP id KAA19721 for ; Wed, 21 Jul 1999 10:32:29 -0400 Received: from hardy-1-p ([192.168.17.113] helo=hardy-1.a2000.nl) by claire.a2000.nl with esmtp (Exim 2.02 #4) id 116xQ3-00053x-00 for DIY_EFI-Digest@efi332.eng.ohio-state.edu; Wed, 21 Jul 1999 16:32:27 +0200 Received: from hardy-1.a2000.nl ([127.0.0.1]) by hardy-1.a2000.nl (Netscape Messaging Server 3.6) with SMTP id AAA316A for ; Wed, 21 Jul 1999 16:31:34 +0200 Received: from smtp1.a2000.nl ([192.168.17.19]) by hardy-1.a2000.nl (Netscape Messaging Server 3.6) with ESMTP id AAA53C3 for ; Tue, 13 Jul 1999 13:15:37 +0200 Received: from backup.mail.unisource.nl ([194.151.224.3]) by smtp1.a2000.nl with esmtp (Exim 2.02 #4) id 113zUs-000677-00 for p.gomersbach@hot.a2000.nl; Tue, 13 Jul 1999 12:09:10 +0200 Received: from esl.eng.ohio-state.edu ([128.146.90.233]) by backup.mail.unisource.nl with esmtp (Exim 1.90 #1) for p.gomersbach@hot.a2000.nl id 113zUr-000206-00; Tue, 13 Jul 1999 12:09:10 +0200 Received: (from root@localhost) by esl.eng.ohio-state.edu (8.9.3/8.9.3) id FAA06407 for diy_efi-digest-outgoing; Tue, 13 Jul 1999 05:00:02 -0400 Received: (from root@localhost) by esl.eng.ohio-state.edu (8.9.3/8.9.3) id FAA06396 for DIY_EFI-Digest-Send@efi332.eng.ohio-state.edu; Tue, 13 Jul 1999 05:00:01 -0400 Date: Tue, 13 Jul 1999 05:00:01 -0400 Message-Id: <199907130900.FAA06396@esl.eng.ohio-state.edu> From: DIY_EFI-Digest-Owner@efi332.eng.ohio-state.edu (DIY_EFI Digest) To: DIY_EFI-Digest@efi332.eng.ohio-state.edu Subject: DIY_EFI Digest V4 #411 Sender: owner-diy_efi@esl.eng.ohio-state.edu Precedence: bulk Reply-To: diy_efi@efi332.eng.ohio-state.edu DIY_EFI Digest Tuesday, July 13 1999 Volume 04 : Number 411 In this issue: Haltech RE: DIY_EFI Digest V4 #407 Saab 900T AMM (MAF) Swap ecu design See the end of the digest for information on subscribing to the DIY_EFI or DIY_EFI-Digest mailing lists. ---------------------------------------------------------------------- Date: Mon, 12 Jul 1999 19:16:35 -0400 From: "C.

Specifically, I'm trying to replace the stock Bosch VAF meter in a Merkur XR4Ti (2.3L Ford Turbo) with the MAF (AMM in Saab verbiage) meter from a '86 Saab 900T (16v 2.0L Turbo). My initial thoughts were that I might get lucky and have a plug-n-play swap (with a little electrical work) since the intake consumptions are fairly close. Even though the Saab MAF has an adjustment screw (What specifically does it adjust?), now I'm thinking this is still not likely since I'm hearing the output curves are different between a MAF and VAF. But before I get that far, I still need to define the 6 circuits on the MAF, and their input/output ranges. I have the schematic, but it only tells me where everything goes. The 4 circuits that route to the PCM (LH Jetronic) are still a question mark. If I had the whole running car (rather than just the MAF), I'd figure it all out in 30 minutes. Anyone care to comment or provide some insight? Thanks, Brad Anesi '88 XR4Ti 5-speed ...and some other assorted German & Italian hardware ...but no Swedes ___________________________________________________________________ Get the Internet just the way you want it.

There is the Corvette starter, ok but... There are three versions of today's small motor (w/ permanent magnets) starter. 1. - standard 4-V6 starter, 2. - same starter with the big nose from the 4.3 V6 (and 350, I think), and 3. - the same starter with an in-line gear reduction unit from heavy duty S10 4WD w/ 4.3 V6. It is longer and looks like a shrunk 350 Diesel starter. It will start anything including pro-stock motors. It starts my buddys 16/1CR 430 alcohol SBC easily. I got mine from the local GM dealer for a $20 core charge. It seems they are noisey and often replaced under warranty. Good hunting -- I'll take ten more if you can find them...

I have heard figures ranging from 105 octane to 126 octane! Will the corrosion be stopped If I blend 0.5% of 2stroke oil in the methanol? I am not sure that methanol and oil even mixes, if not; will 2stroke oil mix in a 15%gas,85%methanol blend? I plan to use two large (very large)injectors with methanol placed before the throttle body, as secondary injectors. The primary injectors are placed at the ports. I will use five 40 lbs injectors as primaries (yes it is a I5 engine) and I will start batch firing the methanol injectors and the primaries above 15psi.

Back a couple of years ago, I offered free copies of my 68HC11 code-seeking disassembler (since GM uses Motorola processors almost exclusively) and have had many people request a copy... At that time, I had no instruction manual written... Recently, I've finished the manual and have posted a new ZIP of the disassembler on my website for all to download, along with some Motorola documents... Soon I'll also have Alan Baldwin's AS6811 assembler (the assembler my disassembler was targetted for) online as well... I am also working on writing several new versions of the disassembler to overcome the limitations of this DOS 16-bit version... Those will be posted when they become available... You can read about those versions on my site... To download the disassembler goto: http://home.midsouth.rr.com/dewtronics (all lowercase) Once there, goto the downloads page... There will be a link for downloading the disassembler... The link will take you directly to my machine where I have the file (we have dynamic IP's so you must go through this front-end)... Because of the IP's, you can bookmark the front-end page on midsouth.rr.com, but don't bookmark anything on my machine directly, as they will be invalidated when our IP's change... ... If you have problems contacting the machine, try later -- RoadRunner cable modems have problems quite often (usually a major crash once every 2-3 weeks!)... I also ask that you fill out the online form to "register" -- I enjoy tracking where my programs go -- so far this one is in over 12 different countries! ... You don't have to register if you don't want to, but I would prefer it and any information submitted will be kept completely confidential... You can also "vote" for versions that don't exist yet to help determine which versions should have top priority... While there, feel free to browse the rest of the site -- though much of the site is still under heavy construction and is very incomplete... Enjoy...

I have checked the lists archive, but I did not see the any post's on putting TPI into a full size 86 4x4 Suburban.The reason to change to fuel injection, is to learn how fuel injection operates, and to hopefully have a better running truck.

There is a lot of work to do, but many resources for the parts & information. How far along are you? Have you decided to go with a MAF or a MAP system or will you use what you can find? You might start with http://www.fuelinjection.com/ These guys specialize in complete conversions or just parts depending on what you want. The complete kit from Fuel Injection Specialties is a whopping $2400!! You can save yourself some major dollars by just shopping around, in fact by watching the ads on: http://128.196.140.199/classifieds/search2.cfm?type=sale&which=part you can usually find complete TPI systems. Before you buy many parts do some research and decide what you want or you could end up like me and have lots of extra parts around that you won’t be using. For instance, with a 350 you probably don’t want to buy the huge 58mm or 1000 cfm throttle body, stay with the smaller version and driveability will be a lot better. Also consider that many of the “speed parts or the week” are made for high revving IROCs and Z28s, a 4x4 is a different story. Read all the info at the Fuel Injection Specialties web site. They can even help you figure out which cable you’ll need for the tranny, throttle and cruise control. I’ve called them a couple of times and they are good to talk to on the phone. Here are a few items I learned along the way. The center head to manifold bolt angle changed in about ‘87. If you use older heads with a TPI intake, the bolt holes in the intake will need to be elongated, since you engine is already built just plan on this modification. The injectors give a better spray pattern if run at fuel pressures somewhat above the factory settings, try 50 to 55 vs. the factory setting of 45. For a 350 start out with the 22 lbs injectors and bump the fuel pressure. On my ‘92 I have to change the mounting brackets for the A/C for the TPI, Fuel Injection Specialties can tell you what you need for your application. Filter your fuel with a good high pressure filter made for the higher pressures in an TPI. DO NOT use a filter made for a carbureted system or a TBI system!! They can burst and create a deadly fire. Don’t fight with the factory wiring harness, buy one from Painless Wiring, see their web page at: http://www.painlesswiring.com/ This harness connects everything from the VSS, to the tranny lockup, to the fuel pump relays, etc... Again, read everything on the web site, but when it comes time to buy the harness, buy it from Summit, you’ll save a couple of hundred dollars. Painless even recommends that you buy from one of their dealers instead of buying from them. Once you own the Painless harness they have very good tech support. But before you buy make sure you know which type of system you are going to use. I don’t mind continuing this conversation on line, in fact maybe it’ll revive this board. However, if you want to you can contact me off line. _______________________________________________________________ Get Free Email and Do More On The Web.

Anyway, I'd appreciate if someone has a solution for this minor inconvenience. I have finally managed to get my Fiat 850, with the MR2 supercharger on it, running. Currently its using the original carby in a blow through configuration (the setup is crap, but will have to do for the time being). With the whole carby being pressurised there is enough fuel pressure in the electric pump to make the car idle, however I'm sure as the pressure builds up the fuel pump runs out of steam. What is the solution? Do you use a high pressure efi pump with a 0.5bar regulator, vacuum/boost compensated to the inlet manifold, so the fuel pressure is always 0.5bar above boost level ? What about the float. The carby currently uses a soldered brass float, will it be strong enough to withstand say 20psi of boost ? Or will I need to fill it with something non collapsable ? What about the needle and seat, will there be any problems here ? Might sound logical, but I'm a bit out of my depths here and so appreciate any answers, on list or off list.

I'm slowly putting parts together for a twin turbocharged small block Chevy (And I'm selling a complete single turbo system for a SBC to finance the TT project, if anyones interested contact me off list) and one gentleman I ran into showed me a float from a 2bbl Holley that was on his Turbo Ford 2.3, the float looked like someone had stuck a straw in it and sucked REALLY hard :) You do have to reference the regulator off of boost however, if you run more boost than the pump itself can handle... The home grown turbo projects I've seen have been on V8's and used a mechanical pump that was modified to accept a manifold pressure reference. The Holley Mech. pumps are easily disassembled for the mods. I'm not sure if you could use a high pressure EFI pump with a low pressure regulator or not. If you do, make sure the regulator is a 3 port (Or more) design that has a bypass for fuel to return to the tank. That way the fuel flow will cool the EFI pump, if you use a "Deadhead" regulator with no bypass the pump will probably overheat and be damaged. I'll take a look at some of my parts books and see if I can find a regulator that looks like it'll work. How much boost are you thinking of running?

Contrary to what the article says, the guy refuses to release the microprocessor code (source or object). Instead of honoring the build-it-yourself spirit of the magazine, he wants to sell it to you. I contacted him twice and now Circuit Cellar magazine are on his case (they were fooled by a 2.5 MB ZIP file that he sent them and contained no article code). Tsk, tsk, tsk! Just my $0.02 cents!

The float bowl of the carb is running in atmospheric pressure, so as you increase carb inlet pressure above atmospheric it sure seems to me that you're going to start pushing fuel (& even air) back into the bowl. I don't know how you're going to be able to work around this pretty fundamental issue. The carb is trying to meter fuel using Bernoulli's principle, so pressurizing the bowl would probably cause other problems. I wouldn't worry about the float collapsing under pressure, but it might tend to sink a bit lower in the fuel when the bowl is pressurized. You would also need to have a fuel pump that was capable of overcoming the pressure in the bowl as well ... The simplest solution I can come up with would be to replace the carb with some sort of TBI unit ... but I don't have any suggestions as to the best source of such a system for a blown Fiat ...

You can fool it by closing way down on the air correction jets so the carb goes way rich at high air flow but than you have two wrong things trying to cancel each other out. It usually doesn't work well, but it can work. It goes without saying that everything in the carb has to reference boost, fuel pressure, float bowl, air jets and including the throttle shafts. You must seal or pressurize the throttle shafts otherwise fuel will leak out under boost. Carbs behave better when used as draw through but that introduces a different set of problems.

The homogenizer was designed for incredible fuel mileage. Smokey was battling pressures caused by expansion of heated fuel, an engineer's version of the Pogue carburetor.

According to all calculations there should be around 16-18psi boost (if the s/c can sustain it). I was thinking of a 3 port regulator but don't know if they come in anything as low as 6-8psi for a carby. Actually talked to a guy last night who told me that there is a mechanical pump available, that drives of the crank belt so that pressure increases as revs increases. I will be efi'ing the car if the set-up works. At the moment I don't know if it'll work and so I don't want to spend money and time trying to get an efi system going until I have proven that the engine will last and it can generate enough power to make the car competitive. I still haven't quite comprehended the carby thing yet, but pressurising the whole setup does seem to work till boost exceed fuel pressure at which stage it obviously runs out of fuel. As for a tbi unit, I'm sure I could make a system of a small Jap car work. Thanks for the effort up to this stage.

The stock sensor wasn't reading accurately enough for me. I picked up a replacement 335 but went with the options for higher accuracy, wider temp range, and metal case. (I don't remember exactly what that part number was). The most direct heat path for these things is along the wire leads. The metal case unit was supposed to minimize that problem.

If you raise the fuel pressure to a level where it will run the car during full boost the carb will flood at low boost. What you need is a rising rate regulator.

If you s/c and try to get everything dialed in with a carb you have a good chance of giving up in frustration or detonating an engine. You can save yourself 1,000s of headaches and hours of frustration by installing a tunable aftermarket EFI system and completely forgetting the carb. Buy a EFI system that is tunable and compatible with a s/c. A couple come to mind such as the DFI and the TEC II. Both are used successfully with turbos and superchargers. There is also good news about the price of these units too, Since the introduction of the Fel Pro EFI that does everything better and faster many serious racers are dumping the DFI and TEC II units as they step up to the Fel Pro ($2400). Even the used units aren't cheap, but certainly less expensive than just a few years ago. Recently I saw a used DFi system with the AIC and some other options for about $800, think that included injectors too. Used TEC II are a little harder to find but they are out there. I have in my library a book written by a guy in the South, describing a complete engine, turbo and DFI build up of a twin turbo SBC. He even gives the setting for the DFI fuel and spark parameters. Cost me about $60, but having all the parameters figured out is worth $60 many times over. When looking at a TBI remember that there is a lot more aftermarket parts out there for the GM unit than any other brand, including the Japanese units. _______________________________________________________________ Get Free Email and Do More On The Web.

Think of a single flare with a collar. If you cut the tube down the length it would look like this: single flare \ \_________ _________ / / double flare |\ \\_______ _______ // |/ The metal flares out, then doubles over inside the flare. The tool is expensive, and it's fairly difficult to get right. You create a "bubble" at the end of the line with "tool A", then cave it in to make the double flare with a regular flaring tool. I've been buying pre-flared tubing at Napa, and bending it as necessary. --steve -- Steve Ravet steve.ravet@arm.com Advanced Risc Machines, Inc. www.arm.com From diy_efi-owner Thu Jul 29 16:47:40 1999 Return-Path: Received: (from root@localhost) by esl.eng.ohio-state.edu (8.9.3/8.9.3) id QAA16787 for diy_efi-outgoing; Thu, 29 Jul 1999 16:47:40 -0400 Received: from mail.ev1.net (mail.ev1.net [216.88.76.5]) by esl.eng.ohio-state.edu (8.9.3/8.9.3) with ESMTP id QAA16783 for ; Thu, 29 Jul 1999 16:47:39 -0400 Received: from ev1.net [216.88.78.59] by mail.ev1.net with ESMTP (SMTPD32-5.05) id AE624C700BA; Thu, 29 Jul 1999 15:49:38 -0500 Message-ID: <37A0BDE5.AD0D95BC@ev1.net> Date: Thu, 29 Jul 1999 15:47:33 -0500 From: "Robert W.

If you look at the top of an ordinary mechanical fuel pump, you will see a small hole in the cover. This is the pressure reference for the pump. Studebaker added a line from here to the blower output so that fuel pressure rose with boost. In case of a ruptured diaphragm in the pump, this would cause the crankcase to be pumped full of gasoline. -- Robert W.

The first step "folds" the end of the tubing back towards itself, the second step finishes the "fold" and makes the actual flare. See here: http://www.chevelles.com/tools/tl4.html.

Double flare is making the little lump on the end of the fuel line. A normal flare gives you a funnel shaped end, a double flare brings the flared out part back in again to produce a little lump (or ring) around the pipe.

My first test failed because of high Nox. This is determined by a formula they come up with that extends the results out to at least 50K at which point my Nox exceeded that limit. (It would pass a standard street smog test no problem) After some investigation I found an Infinity Service Bulletin that suggested adding a ground wire from the intake manifold to the righthand cylinder head. Further diagnostics revealved a lazy or slow O2 sensor at which time I replaced all four. After this I had the vehicle sniffed to verify any changes. The Nox was down substantially. At this time I set all the SRT's and drove approx. 50 miles to make sure no DTC's popped up. Off to the test lab again and failed again with high Nox. This vehilce has no mods done to it. Factory ECU. The only thing I can think of might cause this high Nox would be the design or flow of the tube off the header to the EGR on the engine. Any ideas????

The copper pipe is forced by a tool into a 90 degree cone. Appropriate fitting behind the flare seals it to the nipple. A double flare is really an extruded collar made by forcing a small section of the pipe back on itself. Sort of an instant metal 'O' ring. Found mostly with automotive brake tubing and on most high pressure (80-90) psi Bosch type K efi sytems. They use different fittings. Don't mix them up.

Given that injection at cranking needs to start sometime during the intake stroke it's easy enough to program a timer from TDC to trip at a certain point to open the injector. A second timer set to go off after that can turn off the injector. Let's say at a cranking RPM of 200 an intake stroke takes about 150ms and the injector pulse needs to be 5ms. Best to inject somewhere in the middle of the intake so set the ON timer to go off after 75ms and the OFF timer to trip at 80ms. So we begin the Suck Squish Pop Blow cycle and at the first TDC of a particular cylinder we hopefully squish a good mixture and Pop. At this point, things start to move rapidly. ie: Depending on the mixture, obviously the Pop cycle could be going a whole heck of a lot faster than the cranking RPM based on the mass that needs to be accelerated and the current moment of inertia of the pistons, crank, flywheel (etc.) assembly. If the engine accelerates up to 600 RPM in the pop stroke (50ms per intake stroke) it may happen that injector that should open at the 75ms point doesn't because BDC occurs at 50ms. So a Timer for Injector ON doesn't work; during cranking. If injection was started at TDC during cranking and the OFF timer is used to turn off the injector 5ms later then this problem doesn't occur. However, at some RPM and fuel mixture point the injector will need to be on longer than the intake stroke so now it cannot be turned on at TDC. It needs to be turned on sooner than the Intake Stroke TDC so the timer has to be loaded at a different point. And at even higher RPM the intake stroke may overlap and take as long as 540 degrees of crank rotation. (75% duty cycle so perfectly plausible). So my question is how have other injection designers handled this? How is the high rate of acceleration that occurs while cranking the engine handled. My test bed is an electric motor turning the encoder wheel and this accelerates much faster than the engine so I can simulate a complete loss of injection pulses.

The headers are loosing to much heat. Use all methods to retain heat: ceramic coatings, wraps, paints etc. 90% of emmisions or in 1st 60 sec. of test. Check your cats for damaged honeycomb. Install some small precats at collectors. Use catalyst's with more loading. Get some electric CATS. Install a engine heat recovery system. Try to get a realtime exhaust gas trace to see were Nox is max. During ARB test ask for a cold start modal analysis for precon, this is usally less $ than a bag reading. If dilute Nox is over 30 ppm for more than 3 sec. the car will fail. When car warm it should be < 1 ppm at cruise. You can also get similiar data with any one who has a Nox analyzer, or go to Az. where they do a IM240 or ship it to east coast and I will see what I can do.
