I have JDM Type R motor from 98. I am confused about the ECU to use. I have the JDM ECU but others have told me not to use JDM ECU since its obd 2 and will look for other sensors that the car does not have thus it will run in limp mode. I have the obd 1 to obd 2 conversion harness. Others recommend p28 with hondata that way it will be obd1 ecu. Another person say to run udsm ecu but i have to rewire the vtec solenoid and replace it with usdm vtec solenoid because it has oil pressure switch. I m confused. Why can I just run the conversion harness and use the jdm ecu? Please give me input. Thanks! btw is the usdm type r ecu and jdm type r ecu has different pins or not? Thanks!
