Although I did not get the ignitions done in time
to test this coming weekend there will be other
races shortly.

One of the points Dave Smith mentioned was a missing tach signal.
A tach is an essential part of a racing car.

Since the Lamar ignition fires six times every 10 degrees  right after
22 degrees BTDC that would screw up the tach.  The tach would
read six times higher.

I am now out of PC boards so the next batch will have a correct tach output signal.
4 wires CAS, 12V, Ground and tach.

Got the bread board working today with the correct tach output.
Only required one additional chip.
