I chipped a P06 and coverted it to VTEC for my car. I tested it on a OBDII car converted to OBDI with VTEC. It gave a solid check engine and no codes. I put it in my OBD0 car converted to OBDI and I get no codes. What do you think the problem is? So it can only run in an OBD0 car that is converted for some reason? Its frustrating me. I always test my ecu work on my buddies car because its VTEC and never seen anything like this. Any help would be appreciated.
