I wonder about the necessity of having the module fully programmable. There does not seem to be much discussion about the effects on performance of various shaped advance curves. I suspect that once the curve has been programmed it remains a constant and the tuners simply jet up to it. That Honda VT Nippon Denso unit my mate fitted to his 750SS Ducati, advances from 8 degrees at idle up to 38 degrees at nearly 8,000 RPM. The Dynatek units come with 8 curves and have the option of using a vacuum operated switch to retard the timing if vacuum is lost at high revs, and Jim Comstock has mentioned his MSD unit also retards at very high revs. Back in the dim dark ages when we were playing with two strokes, the Japanese used to contribute to conferences. Their development papers were available through the Society of Automotive Engineers, so even though we were always about two years behind, we had enough info to go fast. I don't believe there would be many amateur racers who go where the MotoGP mechanics go tuning-wise. My feeling with this tuning stuff on four strokes is that to get the best performance, it is as difficult as it is with a racing two stroke. Fortunately I use methanol fuel, so I can afford to be a bit sloppy as long as I'm not too close to the edge in lean-ness.
If you know of any discussions about the effects of various advance curves, I'd be grateful if you would post a link to them. I need to get an overview.
