Good Day Im planning to shove a OBD2 B18C-R into my OBD0 89CRX HF. I am wondering how I am going to deal with the systems that are usually monitored by the OBD2 format like secondairy O2 for cat efficiency and EVAP. Does the conversion eliminate the need for these? Im wondering how others have dealt with this as the other option which I really dont wanna do is to use a OBD1 GSR engine swap. Ideas?
