I just did an LS swap in my EG hatch, but I am not sure which ECU to use. I have a P28 right now, but I have access to a b20 ecu. I will be getting either chipped, but which would be the better to use and if I go with the b20 would I have to get a conversion harness(obd1-obd2). Any info. is helpful.

 

If you get a B20 ECU, yes you'll need a conversion harness. A 94-95 P75 will work perfectly.
