The only thing that may require tuning is R-1 on the CDI board..initial tests it was set at 1.5k ohm..some transistors may require down to 1k ohm to oscillate consistently. Since Rob made the changes to the board design to accomodate either direct hall input or timerboard connections, I think it should be the final version of my board circuit.
Thanks to Rob and his efforts in board design, we now have many different choices that all work! Input and suggestions are always welcome since it is an open source project.
I'd like to hear from anyone building the latest board design. Please post your results so we can all benefit from the results.

Many thanks to all who have added to this great project!
