ECM

I'm missing my ECM for my carbureted 1987 Z28. If anyone knows what ECM and prom I can use and if anyone has one for sale please let me know.

Thanks
Shane

Re: ECM

Is the computer controlled carb and distributor still there? The defacto fix for the CC 4bbl is to get a non-CC 4bbl from an older GM V8, along with a vacuum advance HEI, and dump the CC parts in the junk pile. If everything has been converted, it's probably not worth going back.

I've got a ECM with prom from an 86 305 4bbl auto, somewhere. I'd have to find it. It'd be sold AS-IS no warranty because I don't have a way to test it.

Re: ECM

No I don't need it for the engine I was told because I put a carbureted 350 crate motor in it but I need it for the electrical part of it. If u guys do have one I will buy from u as is my car has power windows cruise locks rear hatch mirrors etc.

thanks

What?

The computer in these cars runs the engine, and controls the lockup converter in the transmission, that's it. "power windows cruise locks rear hatch mirrors etc" are all completely independent.

Re: ECM

The PROM is a Programmable Read Only Memory computer chip that has all the fuel/air mapping information loaded onto it. It also contains timing settings.

I can accept a Money Order, Personal check, or PayPal. Just send me a PM ( private message) here & I'll respond with my info and remaining details.

P.S. Yes,.... there is a Prom still installed in my 87 ECM.
