To get the absolute angle of the flywheel you would need to provide some sort of index. cts_casemod suggested welding two teeth together to get a longer gap between positive and negative pulses on those teeth. This may be difficult to detect or discriminate from a change in RPM especially at very low RPM.
Not as soon as you engage the starter.

I know, I know. But it's a useful place for an airconditioning pump or a pump for the Coanda nozzles. Assuming you even need a ring gear.
