Ok so I just purchased a JDM B18c for my 00 SI, I have been told so many different things as to how to pass emissions. My question is this, I have a obd2b p72 USDM ecu and a JDM obd2 p72. Can I just run the JDM ECU with the JDM motor and pass emissions? If not, how can I run the USDM ECU and pass emissions? I know if I run the USDM ECU I will need a USDM GSR oil pump, is there anything else? Please help I have searched and read through the forum. I just need the right answers because I am going to have to run through emissions next month.
