Default Pcm questions

I have a buddy who has a 94 trans am with a 96 engine and he heard that you can use a 96 pcm in the 94 car. Is this true or not? If so what needs to be done for this to work perfect?
thanks, TOm

Since he's got the 96 engine he should go with a 96 PCM, the car has nothing to do with it.a 96 PCM is OBD II
His CAR BODY is a 94, but when you're talking PCM year, it should only apply to the engine. Do a search, it'll help you alot.

Yep. IMHO, it would be a lot easier to keep the 94 computer and harness and not worry about anything OBD-II on the 96 engine.
