I recently bought a p06 a01 ecu for my d15b7. The only problem is the d15b7 is in a 97 civic body running a p2e a02 ecu. So i bought a obd2a to obd1 conversion harness and plugged in my p06 and it runs really rough. Any Body wana tell me why its running so rough?? it idol great but on the accel it jerks and lags.

ALso is there a diffrence between the a01s and the a02s??

THanks!!!
