The extra yellow spike on the trace. Circled on the attached image.

Once you swap the wires around, there should only be the single coloured spike.

Yellow lines still there?

Edit: this was 36-4. Also some errors on diagnostic display for synthetic tooth and rejected crabk pulses

Interesting. That must be an anomaly of that crank trigger, as the missing teeth aren't missing in the normal way. See attached.

Great news that it's running.

On a scope, it definitely shows as having the missing teeth, this is a scope trace from a Motec on such a car ( running at idle )
I wouldnt chance running the engine at load with the wrong settings and 36-2 or 36-4 can never be right.

Zoomed in a little better to see a full 360 crank rotation.

36 - 2 is the correct setting for that flywheel mode.
