swapping a '97 ECU into a '96

[asian312]

It's a bizzare incident, but my '96 ECU actually went dead on me. The throttle signal is constantly reading 100% and the karmen count is stuck at 3. These anomolies were discovered via AFC, and other problems may still exist. Has anyone heard of this b4?? Know how to fix it?

That brings me to my second part. A friend who recently went DSM link let me borrow his '97 ECU. Since then I've swapped ECUs and been runnin around. The dilema lies that it idles rough and constatly wants to die when coming to a stop (low or high RPMs). After some searching and suggestions, I came across a few threads regarding swapping the '95 E-prom into a '97-'99. My question lies regarding the CAS and the injectors. I've already swapped the wires to rectify the firing order, but have not touched anything else.

Do I have to invert my CAS to gain back my smoothness? What about the injectors?

Last question lies if I swap in a 1G head. Since the 1G and '97+ have the CAS on the same side, would I have to invert the CAS still?

Thanx for the help in advance!

Sounds to me like you wired your AFC wrong and messed something up.

Neither of the symptoms you described in the first paragraph would suggest a defective ECU, and in combination, were the signals actually like that, your car would neither start nor run.

Well my AFC has been wired and in my car for 1-2 years now. It's nothing to do with that. I've check all the connections and it runs flawlessly on the '97 ECU. Even the pocket logger confirmed the same findings (forgot to mention that too Only problem has to do with the roughly idle.

That's y it was strange and I scoured the web looking for a similar incident and couldn't come up with one. It would run, but it was stuck on the base map for WOT at 3hz. Much like when u first romp on the pedal at a stop. I managed to drive it up to ~10 mph, but there was too much fuel being added to allow any highewr speeds.

But thanx anyway DrZiplok. Don't worry another very highly intelligable friend came to the same conclusion and was pretty gun-ho about just slapping in a '95 e-prom. Then again I just might.
