The hardware solution was getting too complicated and using up too
much printed circuit board space. I never got it to work perfectly
either and I was spending a lot of time doing it. The Teensy is only
about 1.4 inches long and .7 inches wide. One Teensy per coil and one
coil per spark plug for high redundancy and safety. Cost only $20. I
can get 4 Teensy on one printed circuit board with4 voltage
supplies.

The Teensy is way way over kill for this project but the cost is low.
I could probably do it with a BASIC Stamp but it does not support A
to D and hardware interrupts. Hardware interrupts are the best way to
deal with all sorts of mechanical things. If you don't have 4 or 5
you don't have squat :) It is like having 4 cell phones in your
ignition system :)

So I wrote a program in QB64 to see what it would look like.

The idea here is break the RPM into ranges. Say every 1000 RPM. For
each range the coil would trigger six times about 5 degrees apart.

This may not be necessary so this prog is not cast in concrete yet.
It took less than an hour to write as I am a bit rusty :)

Neal, send this to Dominic. I would send it myself but he does not
answer me so I don't know if he is getting it.

Jeez I hope your cell phone is a heck of a lot more reliable than my POS
cell phone :)

What is a POS cell phone John? Bugs are rarely the fault of the chip used.
Big hands and fingers don't work well with the typical smart phone.

My BLU 8 inch Fablet  works fine. It is just a bit slow now and then.
I have big hands :)
