If we could find a way to invert the pulse stream and amplify the curent this might give you a means of firing the injector. Timing was/is by means a magnetic reluctance device, so stick the magnet on the crank and the sensor somewhere adjacent; moving it about will let you change the timing.

Moving the coil (to advance/retard) is too crude, I think.
My guess is I'd need some sort of electronic time base which would represent 360 degrees and some way of recognising where to switch the current in. Trouble is, I'm out of my depth.
Any help gratefully received (I never intended getting into this side of things - my expert helpers seem to have lost interest despite being fed beer etc)
