Default Re: ignition timing adjustment methods

Interesting thought about timing changing with engine speed but if the system is triggering on the 0V crossing point I doubt it would change much if at all. When you consider the speed of switching a transistor and the much lower top rpm of the engine it doesn't seem like the CDI would really see a serious change. Since the engine idles around 1000-1500rpm or so and has a top speed of around 9000rpm that would only be a 1:9 - 1:6 ratio change in the frequency change of the ignition speed. Not all that much for the size of the windings in the magneto and components in the CDI.
