Does anyone know why I can't get my P0B ecu from a 1994 accord EX to run my f22b? I'm running the engine in my 92 prelude SI. I know some people will automatically think that this isn't the normal ecu to use for this application, but I'm not looking for the absolute best performance right now.

My P14 runs the car just fine, but my knock sensor is gone and I just want something that won't trip a code and send the car into limp mode.

From what I've learned any 0BD 1 F series 2.2L ecu should run the car just fine. My only issue is when I bring the car to an idle, the rpms fluctuate, struggle, then finally car stalls. No codes are showing and the ecu really rips the car well when I'm on the gas.

Any insights would be awesome.
