Probabally could be done with some simple circuits, or even a PIC, and you
could just dial in your advance curve. Would require some thought to make it
all work. And yes, the standard 4 prong HEI module does not advance the timing
when fed digitally. It is the increase in voltage at higher RPM that cause the
trigger point to be hit sooner. Halleffects don't have that problem.
