That seems to be a programmable ignition. I want something that gives me a curve of an existing cdi... I am probably going to go full analog and make a motor that runs a crank stub with a flywheel on it.
But it would be sweet if I could get it into the digital world.
This guy Gompy (real name Rob) posten al lot of stuff and tutorials online about building your own programmable cdi ignition. Complete with parts lists, software and how to make your own circuit board (with UV light and acid).
I read a lot of gompys stuff a few years back,could never get a clear path to take as he always would be changing directions... Here is another site that has some good info; www.sportdevices.com/ignition/ignition.htm
The issues with two strokes and ignition timing are many. The CDI curves are quite luck of the draw", in some regards. High performance ones have the same issues.
One example: Many MX'ers not many years ago would play with swapping CDI's...a CR125 for a 250, say. Some times great results...other times poor or detonation.
On carbs, even one needle position (Leaner) can ruin an engine at high rpm's. You think, what? I have perfect main jet size, but your transition from the pilot performance to the main, with improper timing may have begun the damage.
I recall a Honda MT-125R that would blow by me in corners, but never get good enough top end. Hmmm. So many things it could be. Turned out to be a setup from a CR-125, different ignition timing, same everything else. It blew up quite often. Not enough retarding from 12,500 to 14,000 rpm. Those were total analog days. Easy...not really recordable.

Fox: www.gofundme.com/29mgf6b8 I hope it is ok to pass on his gofundme page link. If not you will un-post it I'm sure. Thanks again all!!
