Description

The all-new capacitive discharge ignition will easily connect to nearly any 12-volt negative ground distributor system. This advanced micro-controller manages a built-in two-step rev-limiter. The spark output reaches up to 535 volts of primary voltage and 135 millijoules of spark energy. Multiple sparks burn in the cylinder for 20 degrees of crankshaft rotation to ensure complete combustion. Two rev limiters are included: one for high-end overrev protection and another for launch control.
