OBD2 PCM Compatibilities

[SappySE107]

I have the DHP chart but it doesn't tell me anything about swapping a 97 or 98 pcm into a 96 achieva. Friend of mine just got an achieva with a blown motor and new trans, so we are swapping a 3400 into it (modded cause I can), and I would like to tune it. If its a plug and play deal, that kicks ass.

so are you asking if the wiring is the same?

Please say there is a PCM with the same wiring, I haven't gotten the temp control fixed on my Weller :/

I have my weller that is identical to yours if we need it.

Wiring would be vital for compatibility.

Yeah, I found out the deal in the iron itself that controls the temperature is shot on mine. Had to bypass it for it to get hot so I could splice in a replacement harness on an Envoy. You bypass that bad boy, and that thing gets HOT right now!
