I probably wasn't clear---sorry. With mapped electronics firing through the dizzy it basically only functions as a mechanical reference point. The advance is controlled by the hardware/software. Compared to using the crank as a mechanical reference, the dizzy is less than optimun, for obvious reasons.

I'm curious, however, about just how much real world difference between driving a car with a dizzy and mapped electronics and a car with crank trigger w/ the same hardware? Is it a lot or is it a more theoretical difference? Conventional wisdom on the matter says there's a significant difference, but practical, seat of the pants, experience can be very different.
