Re: OBDI Tuning Looking at this from another angle....The grand national... its already set for my style of ignition setup. Maybe thats a better route.

Re: OBDI Tuning WOW... I'm reading this thread again, and I can't believe you guys had as much patience as you did. Just an update: A few people are working on the 1228707 ECM, and the following has been located: a. Rev limiter (fuel cutout and re-start) b. Speed limiter (fuel cutout and...

Does anyone have any links to tutorials for creating a definition file? Thanks, -Joel

Re: OBDI Tuning Thanks for the post. Now I'm a bit confused here about the direction your pointing me in. I have the fuel, coolant, and timing maps for the lotus engine. I can't use the 5500 RPM - 7000 RPM range due to the fact that the Lotus utilizes secondary injectors. I could probably...

Re: OBDI Tuning Take a look at this: http://www.andywhittaker.com/ecu/ecu_crossref.htm Every piece of ignition component came from the Quad 4. Do you think its possible that the two proms use the same definition file? I thought I'd ask, even though its a long shot.

Re: OBDI Tuning The only person who has the definition for the Esprit sells it for 500 Euro. Yikes.

Re: OBDI Tuning Is that hard to tweak? (the pinout values?) ALSO: The Lotus uses the same style injectors as the Quad 4. I just have to upgrade from the 33lb injectors to the 36 lb injectors (dirt cheap from Ford Turbo Coupe, even refurbished). The cam specs are very close. Lift and...

Re: OBDI Tuning Yes my car is MAP based. The lotus engine uses similar lift, with more duration on the cams from what I gather. other than that, the engines both have the same distributer-less ignition system, ECM box, and are within 100cc of eachother. They both use the same injection...

Re: OBDI Tuning I also wanted to point out that the 88-92 lotus Esprit Turbo used the same ECM as the Quad 4. (1228707) That is probably the best starting point. I'm looking into whether or not that car used a distributer or had the same firing order. GM owned lotus back then, so I know it...

Re: OBDI Tuning You guys I have found a new development. I have been told from a good source that there is a turbo code out there for the quad 4. Initially the Quad 4 was slated to be turbocharged and one year has a dual .bin file loaded into the ECU. I've been told that all you need to do...

Re: OBDI Tuning One major thing I'm looking at is the fact that the 88 Quad 4 ran on the same ECM as the syclone. That could be a nice shortcut.

Re: OBDI Tuning thank you very much for the link. Does anyone here have experience with ladder logic and programming CNC equipment? Any similarities with this tuning software? By telling me to go with the Syclone ECU, are you telling me to basically take the Syclone programming and change...

Re: OBDI Tuning I'm going to alot of research on the sunbird ECU/chip when I get home tonight.

Re: OBDI Tuning I was trying to imply that the 2.0 turbo motor bin was a bad idea. What is wrong with the "bandaid" ideas? alot of these items (injectors, Adjustable Cartech FMU, AFPR) are mechanical and really won't be unreliable. The only programming that would be needed would be the MSD...

Re: OBDI Tuning Well, keep in mind that my cylinder head flows about twice as much, has 2 cams, and makes about 40 more horsepower without a turbo in stock form. The firing order is the same, but the wiring is different. The turbo 2.0 uses a distrubuter, the 2.3 does not. That means...

Re: OBDI Tuning Do you truly believe it will cost $2000+ for a dyno tune? Thats how much a Tec3 would cost me. You could tell the dyno tuner to optimize the timing, and A/F for safety and not peak horsepower. Just throwing it out there... When you begin editing, are you only editing the...

Re: OBDI Tuning Thanks, I appreciate the info. The engine is a quad 4. in 1988 I believe they used the same ecm as the sy/ty and turbo sunbird, but that year the the crank had a 15 degree difference I think. Here are the possible ALDL definition files: A089 1989 LG0 vin A A092 1990 LD2...

Re: OBDI Tuning I'm well aware of what ECM I'm using, and the chip. I do not know how to edit a chip. Is there software available? As far as I can find, nobody has bothered to try editing this chip. Even if I had a decent understanding, I'd rather have a professional do it who has more...

Re: OBDI Tuning As you can tell, I'm trying to do everything I can to avoid a stand alone.

Hello, I wanted to shoot a question out there for you guys. The car is not a Sy or Ty, BUT I wanted to ask an expert on GM OBDI Turbo cars. I'm not an expert but I do know a bit. Here we go: I want to tune my car for a turbo application.I bought all the necessary forged internals, now I'm...
