the PCM'* are the same....its the EPROM that is different between the Motors, and or trans.

and when you get a custom PCM for your year, the EPROM is the only thing that gets burned

well just look at the timing a */c car gets 15 degrees max timing and a L36 goes up to 26 degrees so it wont work youre going to blow that engine .its only good as a core if you need one for custom PCM

Again.. The 94-95 PCM is the same regaurdless of L27,L36 or L67 for the 94-95 Model years..

If its a 94-95 GM Minivan with the 3800, 94-95 GM C or H body with the 3800 It will work for you....

What you will have to do is swap out the EPROM from your PCM to the Replacement PCM.. The PCM for the 94-95 does not contain the programing, The EPROM contains the programing...

If at all possible I would recommend a GM Reman PCM... But they cost a bit..

1996 was the target date for OBD-II implementation per C.A.R.B. for all autos sold in California. Fed clean air act made it national in 1990 with the same target date. Only problem, the standard was still a work in progress.. GM took the entire time to phase OBD-II in...even then they didn't do the complete OBD-II implementation until a few years later. (Don't feel bad, my '94 V6 F-Body has a screwy PCM that was only used for 3 months of production.)
