Product details:

The ignitor ii has many of the same great features that the ignitor has, but its 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. High rpm performance is improved when used with the flame-thrower ii super low resistance 0.6 Ohms and 45, 000 volt coils.
