I would think classic retrofit could do something similar. I’m sure their circuitry takes up more physical space, but it seems there would be a market for this. A programmable curve in a stock looking box to plug into a locked dizzy by JB racing or similar. They recommend using MSD, but I prefer the stock look of the Bosch cdi boxes.

The issue is heat dissipation, for high RPM in a high ambient conditions, a stock Bosch CDI will see a case temperature of over 80 deg C. You put twice the energy in that little box and I think you'd be into forced internal cooling with a fan.
Bob has clearly been playing with this. How are you managing the heat Bob?
