Yeh that's what I figured. I put the standard computer in today. The car seems to run fine. But check engine light is on and tacho not working.
I hooked our scantool up to it and it has no codes and the computer is getting an rpm signal.
Anyone got any idea what the problem is?
If I can get it all fine without bus tuning I will leave it.
I was thinking maybe the mil wire and tacho wire in the ecu plug may be the wrong way around for this computer.
