ECU Questions
Hello All:
I have a 1991 CRX HF with a ZC engine conversion. The engine is also out of a 1991 model car, but the ECU is from a 1988. The car will start and run just fine and throw no error codes with the 1991 HF ECU, but with the 1988 ZC ecu it runs roughly and throws all sorts of random codes. I thought of the possiblity that the ECU is fried, but it does the same thing with the ECU out of my friend's 1988 Si which runs just fine.
So, my question is: Is the ECU out of a 1988 model car incompatible with the engine or wiring harness of a 1991 model car?
