I have a 94 civic with a B18b swap. Tha swap was completed before I purchased the car. I noticed earlier that the ecu was a P06. I knew this couldn't be right, so I opened the ecu and saw that is was chipped to a p75/pr4. My question is, is my ecu still running obd1?? Sorry for the simple question. I searched forever on this.

 

yes the ecu is obd1

 

Thanks!
