I have been using it to test my engines Charlie...the thing is it jumps timing all over the place after about 2000 rpms... making the engines run hot..and I get preignition noise. When I went back to the Synchro Spark, all the problems go away. So it's either not tracking rpm correctly or the table values are wrong, which I can't change since I am not that good at the excell sheet with copy and paste. It's got to be a steady increase in timing advance up to mid rpm range..just seems odd that it jumps back and forth at a small rpm increase.

The old code worked for me, the only problem was lag and bad presicion on high rpm, but should be usable on low rpm plane engines.
I think you have a code/compilation problem?

PM me if you want to sell the old timer boards.
