i traded with rx7tocivic's pr3 chipped ecu. he also made me a obd2 harness im not sure if this is a obd1 or obd0 ecu... i am selling this so i can get injectors and afc.. the afc seems easier to tune with... i have not used this ecu yet he said it was programmed for 450s ... $115 shipped or trade for vafc in working condition...
