Ok guys just converted to obd1 with my accord f23a1 auto to H23a vtec using the old f23 trans. The problem i am having is on cold start up the idle surges 1-2k then after 5-10 surges evens out, but still high(around 1200rpm). when i put it into gear it jumps up and stays up. Under brake or...
So i ordered a obd2 to obd1 custom conversion harness that will use P28ecu and original f23 ecu to run transmission. Am i going to have to switch fuel rails, distributor and possibly alt? Thanks for all the help guys this swap is a nightmare.
Just finished my H23a VTEC swap and I am having the hardest time finding the right ECU to run. I kept my orginal f23 auto tranny and can find no info on my tranny/engine setup anywhere. Does anyone know which ECU will work best? Please help!
