I have a 98 civic ex VTEC, and i was wondering about changing the ecu to the spoon obd1 ecu.....will it damage my motor? i was planning to upgrade my cam, should i do that before or after the ecu upgrade? i have 120 000 miles on the engine, will that make a difference? I wanna know any precautionary steps before upgrading anything on the car
