DIM Electronic Advance Ignition

I fixed a problem in a calculation, it was a rounding issue in the integer math used to calculate RPM and timing advances. The bumpy green line in the user interface plot is now smooth. Now the system is working well enough to test.

I only have the time to work a couple hours a day, so it will be a few days before it is put on the car. I have a couple other projects in the way.

The pdf capture of screen shot does not work well after compression to fit the post requirements. I do not have time to mess with that now. I might find a solution over time, possibly a youtube video. The user interface is not required, however the ability to log and present data is useful.

By making acceleration runs, changes in timing can be checked to see how the engine responds. A sort of on car dyno.
