PROM Compatibility
I have a 1986 IROC-Z Z28 305, automatic Camaro I picked up a 1988 PROM I made sure it was for the right transmission and engine, but when I popped it in the car turns over but wont get started. Is there something else I need to do to get it to run?

Re: PROM Compatibility
I did have the computer replaced, it is a remanufactured one from carquest. I don't know if that is the issue.

Re: PROM Compatibility
What is the 3 or 4 LETTER code on top of the PROM?

Moving to DFI & ECM.

Re: PROM Compatibility
That PROM has VATs enabled, injectors won't fire. If you want can get a VATs eliminator box to send that signal to the ECM.

Re: PROM Compatibility
