Ignition Spark Edge
The ignition spark edge determines the polarity of the waveform used to drive the ignition module. Falling
edge ignition will use a zero voltage output at idle, a +12V signal for charging, and a falling edge to zero
volts to fire the spark. Most factory ignition systems use falling edge. This is the default setting.
