If I had the time it would be a fun project. Actually a member here (blitz22) designed and built a very nice CDI prototype, more advanced than the Kokusan. We talked about this, adding a PV controller. I remember asking for a governer for him to study and derive the actuation curve. I guess he got busy with real work projects. The nice thing about the electronic option is you can make it open exactly as you want and match the ignition curve. So, if you have a multi map ignition you have a multi map PV as well. The problem I see as an aftermarket part is mfg enough to keep the price down. The PV controller/CDI could be generic for all Kokusan fired 2strokes, and the actuator interface brand specific.
