The closest trigger wheel style that megasquirt is compatible with is a missing-tooth style where there are a number of teeth (like 30 or 60) with one or two missing. I could try to modify my flywheel by knocking off a tooth or two, but I am afraid that I'd end up breaking off additional teeth due to the added stress during starting. Basically, I didn't see an easy way to add a crank trigger wheel to the backside of the engine.
Would a dual wheel configuration work with this?
