Summary of change:
I have recently discovered a problem when a secondary trigger signal is connected to the ecu but is not being used. The results is that the trigger signal somehow makes its way to the primary trigger causing a LESS PTRIG error. I set this up on the bench and recorded a trigger log turning the secondary input on and off. It´s very clear that the signal is occuring once per cycle. Also uploaded is when the secondary trigger is enabled so it´s clear that it´s the secondary signal.

When running "Missing tooth primary allow sync without camsync recieve" there seems no way of telling which stroke the ecu will fire the sequential coils and therefor 50/50 change of getting the engine running. Ideal would be that at any time when ecu has no camsync it will run dual out (If the ignition setup allows it, and wiring should really be forced/suggested so this can be taken advantage of). Does the ecu swap strokes in an attempt to get the engine running?
