Hi i have a 99 accord f23a1 that i converted to manual i got a obd2b to obd1 conversion harness and a obd1 ecu socketed and chiped. I put 400cc injectors, t3t4 turbo, walboro 255, ssq blow off valve, and tial 38mm wastegate but it keeps going in limp mode no matter if i use the stock AT ecu or the obd1 and has surging idle with both ecu's. I've tried disconnecting the IACV with obd1 ecu and that didn't help. If anyone could help i would be http://images.ibsrv.net/ibsrv/res/sr...s/thud.gifmuch appreciative.

 

Ok, I'll bite.....What codes are you getting?

 

with the stock ecu the only code I get is transmission malfunction. Is this enough to cause limp mode?
