Brett... If you can use the timing light feature (flashlight led), You may be able to see the timing change after it reaches 1000 to 1800 rpms. First spark sets the delay, then it follows the curve set in the software.. but it must see rpms as stated in the c-code to track it and change the advance..

My test setup only started to read at 1000 rpms with the timing light, but it does work. Setting the delay lower causes problems since that would yeild negative numbers and give an assembly error when you compile it.
Just my point of view.

I spin my motor with the plug out of the head with an electric motor (these are weedeater motors I convert), no chance of the motor backfiring or having preignition till I get the timing set.
As I vary the motor speed, I can see the degree wheel rotating in the timing light. That's how I tested mine.
I know your setup is different, but they all work the same from what I have seen..built 9 of these now and all function for me.
I just etched the newest CDI-TCI timer board..will have to see how that one works tomorrow..
