get an obd2 motor, but run an obd1 computer if your chassis is obd1. my car is obd1, my motor is obd2, my ecu is obd1, so i only read the obd1 sensor.

the gain of the obd2 motor??? lower miles, and it's running in obd1 so whatever power loss that's associated with obd2 (i don't think there's a power loss just a myth) it's not present cause your od2 motor is running obd1
