Summary of change:
Stock C20LET engine 4cyl, Stock injectors New intake air and coolant sensor installed New engine harness Coil on plug (4 VAG cop) ---- '''Trigger''' * Stock primary(VR 60-2)(resistance ~500ohm) * secondary(1window HALL) non adjustable triggers. Should be easy setup (make sure grounds are connected properly) * order ECU with VR, HALL * make some DC measurements (eg. VR DC bias voltage) * connect VR trigger with good polarity * capture triggerlog ** verify VR trigger polarity * setup 60-2 (4 cyl) with camsync ** easy if sectrig is at sane position (as usual for opel/GM) ** the chosen edge: either rising or falling edge of sectrig should be away from tooth0 (pulse after missing tooth) * strobe and fine adjust ---- '''High RPM''' There are '''trigger error and missfire on higher RPM'''. Common causes: * ground connection problem * sensor mounting vibration * wheel "runout": ** if some tooth amplitude are anomalyously big or small (or varies throughout the cycle because of "excenter") ** can be cured by fixing the mechanical setup, or by cheating: suppressing the adaptive threshold (greater value R181, R182 ?) * ECU test: feed m582 sound signal (from notebook or small MP3 player) to the VR trigger. The ECU VR input should sense well beyond 10k RPM (even with auditrigger, which is 135 pulse, not just 60-2). ** do NOT flood the engine ** note: (with 60-2) 115200 baud triggerlog needed at idle RPM or higher. ** above 6000 RPM, vemslog can be more useful than triggerlog ** if any problem, also use scope Although unlikely to be of issue, a simple test (to see that internal 5V1 zener "voltage limiting" is functional): * disconnect primary trigger sensor, and apply 12V to EC36/27 VR input via 4k7 or 10k resistor (take note of the details, including measured resistance and VBATT) ** measure voltage on EC36/27 ** measure voltage drop on the resistor
