Have a question for '81 owners.
Does anyone have a scanned image of the wiring diagram for the PROM in the ECM? Or do you know if your car uses the "C4" emission control computer system?
Thanks,
Matt

I think you're getting in a little deep for me. I have a wiring diagram for the car, and I know the PROM is there, but that's about it. Sorry.

I know that Adelphi is doing all the GM computer stuff these days but even now they wouldnt give you that kind of info. this is now delving into design territory and I dont know who was doing the computer stuff back then.might try some of the after market chip manufactures maybe someone from tech can point u in the right direction. I know that there are programs out there that let you modify on board pcm,s that can be run on the laptop with correct cable but I havent seen any thing like that for stock cars of this era.
