The Ignitor II has many of the same great features that the Ignitor has, but it's smarter. Ignitor II units sense the coil current level and use a powerful micro controller to adjust the dwell. Variable dwell helps to maintain peak energy throughout the entire RPM range. Ignitor II systems develop up to 4 times more energy between 3000 and 5000 RPM than standard ignition systems. Ignitor II applications cannot be used with solid core ignition wires.
Ignition box performance without the box. The Ignitor III is the most advanced points replacement kit yet. It is lterally an ignition box inside your distributor. It features multiple sparks throughout the entire RPM range and a high resolution REV limiter accurate to +/- 50 RPM which is set by the user. The Ignitor III module generates 5 times more spark than points. This of course means more spark energy creating more horsepower and better mileage.
