Hi, I am new to the forum. I just bought an eg with a b18c1 swap in it. I discovered that it had an LS p75 ecu, which I am obviously going to replace with a p72. My question is, due to the drastic difference in pricing that I have found(obd1 go for 100-200, obd2 for 50-75) it would work just fine if I bought an obd2 ecu and an obd2 to obd1 conversion harness, and plugged it right into my obd1 wiring harness, right? Also, would I be better off spending the extra money on the obd1 now, since I plan on building the engine next year? I plan on doing a mild 200whp build, and have already accumulated some of the parts. As far as I can tell, most conversion harnesses are for putting an obd1 ecu into an obd2 car.
