The other system is the CD, or capacitive discharge, ignition in which a capacitor stores electrical energy and releases it to the coil. In these systems, more or less voltage does not affect the ...

While we were trying to perform an apple-to-apple test by not touching the timing of the engine, we were in fact reducing the ignition timing due to the way the Ignitor III works.
