So, what about this? ---->>>
The engine has a 16" dia flywheel (very thick but that's another matter). It has convenient mounting points nearby. The circumference allows exactness.
If I built a small structure that bolted onto the crankcase and had an adjustable extension to contact the flywheel face, we could get a pulse off the f/w by adding the other part of the contact (say a piece of silver) to the f/w. If the silver was roughly triangular, by moving the contact back-forward for advance-retard or up-down for dwell, we might have a useful circuit.
But I don't know if the charge would build fast enough to move the inj solenoid. It would probably need a condenser (discharging) to help it. But it might work, ie going analogue when I assumed (out-of-my-depth) digital.
Comments welcome.
It's all at a planning stage at present.

i think your thinking the same way as what i was getting at the dizzy cap idea.
i meant it to be used to open the injector rather than the a spark. but it wouldnt have gave you much room for adjustment for timing / duration
HDI the fig came from Vagcom group 122 ( i think ) dont know how accurate it is thou. was 172 ish on standard unleaded
