Alright guys...I am in need of some help. I have a 96 Del Sol Si and I need a new ECU. Now I have looked at my ECU but it says that it is a P28. However I know my car is an OBD2a car and P28's are OBD1. Everywhere I read says that I should have a P2P in my car witch goes with the D16y8. However my P28 ECU is plugging into my OBD2a harness. Any help would be appreciated. I am trying to get my car to pass these stupid emission test.
