I bought a 96 civic hx coupe with 93 integra b18a1 obd1 with gsr tranny. I want to convert it to obd2a 96-98 integra ls ecu, so i can pass smog in cumberland county north carolina. can anyone tell me who has already been down this road what cel codes am i gonna get once i swap to p75 obd2a and how to get it to pass smog. i do plan on swaping back to obd1 once i pass smog since i guess theyre better to tune. also will i get cel codes once i swap back from obd2a to obd1...
