Feasibility: Engine Ignition controller

shadowplane676:
the question is, would it work.

I'm reasonable confident that it would be possible to get it to run the engine, and the high speed timing requirements don't seem to be a problem. It's the low speed characteristics, especially while cranking, where I would anticipate the worst problems. I suspect it might take a considerable amount of trial and error to compensate for the variations in cranking speed during a crank cycle, and this behaviour will probably not be consistent from cycle to cycle, and will probably also vary with changes in ambiant conditions.
