John,

Your project sounds impressive and I would like to try one when Its avalible. I admire your effort in this as I know the work involved in creating a reliable ignition system. I played with this back in the day and had a very robust fixed ignition unit developed that I utilized "straight up" or with mechanical advance to do "weedwacker" conversions. My project ended when I got frustrated trying to solve the electronic advance - Packaged development boards were not here yet and PIC programming was my Nemesis. I spent many hours hand winding experimental toroid transformers and coils.
