This CDI is more than just a rev-limited CDI - the power gain comes with the well-thought-out electronics from the engineers at TOP Performances.

Ideally, an engine needs an electronic ignition that varies the advance - the ignition timing - based on the engine speed. At high RPMs, the ignition timing must be delayed to reduce the load on the piston and crankshaft. With a variable advance, the ignition point can be adjusted to match the engine speed.

This way, maximum power developed by the engine is achieved at any engine speed - increased acceleration and speed!
