Removing the ignition timing aspect of the above by triggering the ECU from a non cam belt driven source is a large part of the solution.

How big of a problem is the fluctuating ignition timing??
To be hones, i knew about the drawbacks of using a cam driven sensor for crank position. But i never knew it was a problem until now.
Did i do the right thing in selling my pfc, and going for the autronic?
