I am in the process of swapping a 165 ECM into my 85. I have a memcal but I do not know what it is from. I am going to burn my own EPROM.
Are the two other chips on the memcal unique to each memcal type. Do I need a memcal that came from a Corvette with a 4 + 3 trans or would any memcal from a V8 work.

Preferably yes, but I can tell you right now that if you ever end up in limp home mode that overdrive will not be available to use even with the correct chip. Don't ask how I know.
On the PROM inside the memcal there should be a 3 or 4 character broadcast code. For example mine is ABTB. Let us know what you see on it and that will tell us what it is from.
I think the APYU this is from a Firebird w/auto trans. If I want to get rid of the cold start valve should I start with a 89 memcal like ABTB? I think it is from a Vette with a 6spd. Or should I use the ABTB?
