Issues with triggering:
60-2, trigger tooth = 3
Trigger ref: 0 20 40 60 80 100 (tried also 0 20 40 0 20 40)
6x individual coils.
Ignition output firing order has to be moved down by 1 in order to even attempt to catch.
But the issue is mainly that it seems that the ECU will not wait for the proper sync/cycle... it will try to trigger at any time it wants cause to backfire in intake or sometimes exahaust or anywhere in between. Sometimes it catches properly and engine rungs great.
How is this even possible?
