Ok, so I've figured out that my car has a bad ecu. It's currently a p30 with a SST chip. The motor is a 1992 JDM B16A1. My question is, does the ecu have to be specifically for a DOHC vtec, like an obd1 gsr, del sol DOHC, etc. Should I be looking at another p30, or should I go p28? Thanks in advance!
