Hi Charlie,
We are making progress on Nyemi's code for the old timer board.
Trying a few different curves in the Excel worksheet seems to do the trick as far as mid range throttle transitions problems go.
The rest of the code was working before with the exception of the test feature.

I test ran 2 different engines with the changed curves. He tried a small change in the lookup for timing delay which worked really well.
The rpm based timing delay needed tweaking according to the test bed we made up with an electric motor and magnets embedded in a plastic disk on the shaft. Tried one magnet first but ended up adding 5 more for balance reasons. The timing strobe I built from this forum proved it's worth for sure. Accuracy is great!
More changes in the works for this week.

John
