Electronic Gurus

I decided to do ahead and post here the best I could. Many of the AVR freaks guys are much better programmers than I, exposing my code there could be a disaster :).

Here is my post http://www.forabodiesonly.com/mopar/showthread.php?t=326021

TailBeast,
You know there are some hints in all this, for you to make electronic advance control for the GM HEI....

The period between ignition cycles on a V8, is 1/4 revolution is 90 degrees. The period measurement gives you timer counts, subdivide that for timing control. That is the basis for my ignition control, except my timing sensor is more usable, it gives me an edge for max and minimum timing. That puts the target in the desired range, increasing accuracy.
