I installed a 93 mr2 ecu in my 90 3sgte. I repined the harness plugs to work with the new ecu. The car drives perfectly but wont idle correctly. It will sit at 650 rpm and want to stall out. Then after a few min of driving it will bump itself up to 950rpm for the rest of the drive. If I put the car in diagnostic mode, it will stall right out.

I was thinking maybe it has something to do with the IAC valve, but wannabe confirmed they should be the same. I know 93s have a slightly different throttle body, so maybe that has something to do with it.

Anyone here use a 93 ecu on their 90-92 motor?

Cool - I'll try that. But not to distract from your problem - I'm just trying to offer some of my experiences so that if any of them sound like yours we can use mine to maybe help you.
As I said - If there is anything I can do to aid you LMK.

Its a safety feature so that people like you don't end up killing themselves or everyone around them.
