i am having troubles with my set up. i am running dsm 450s with a chipped p28 converted to obd1 in a b16a2 engine. i changed out the resistor box because my injectors were ticking like hell. so now im left with a solid cel. my tuner tried his known good ecu on the car and it still threw a solid cel. now i dont know whats up with it. my car will start up and then die instantly. i am resurfacing all my ground wires. what else should i do?
