takeup Posted November 4, 2021 Report Share Posted November 4, 2021 When cranking, the trigger is not recognized The output of the crank sensor is normal because it is recognized by the normal ECU. I don't think it's recognized due to a logic problem with the LINK ECU. I would like you to verify it once again. Quote Link to comment Share on other sites More sharing options...

takeup Posted November 7, 2021 Author Report Share Posted November 7, 2021 I will send you an image of the trigger. I think the trigger Count from 3 teeth or 2 teeth Whether to recognize the rotation by counting from It seems to be. Can anything be improved?

Adamw Posted November 7, 2021 Report Share Posted November 7, 2021 It would be better to attach the triggerscope file as it contains info about where the decoding is failing. But from your picture, I would say the most likely problem is the spike that you have in the middle of some teeth. This looks like perhaps a wiring problem causing electrical noise getting into the trigger signal. Try another trigger scope with the ignition system/coil disconnected to see if that fixes the spike.
