u dont need a knock sensor, cold start valve, or anything really. all i have is 2 bar map sensor (get a 3 bar if u want to run more than 14.6 lbs of boost), 1 wire o2 sensor, fuel pump relay added on mine. u specify if u are running high or low impedence injectors when u order. if u need the resistor box, ur gonna have to buy it from sds/racetech.
shit is realy easy to hook up. u keep some of ur existing wiring harness- basically the shit that reads ur gauges, ignition key switch, stuff liek that. all u are doing away w/ is the wires that controled the coil and the fuel delivery. if the sds ignition box is f’d up–which is the ecu, then he hooked it up wrong and burnt it up.
