The Ignitor III module is in a class of its own. Think of it as an all-in-one, self-contained ignition system that doesn't require an external box. The Ignitor III provides five times more spark energy than points and even supplies multi-spark throughout the entire rpm range for improved combustion and increased burn time. Adaptive dwell maintains peak energy throughout the rpm range that reduces misfires and adjusts spark timing at higher rpm to compensate for inherent electronic delay. What's more is the Ignitor III even senses startup to develop more energy quicker for easier cold starts. And with a built-in rev limiter (accurate to ±100 rpm) it's the perfect upgrade to an existing Flame-Thrower billet distributor. Once the engine hits the limiter, the module cuts spark-saving your engine.
