Pertronix 91542 Ignitor II Adaptive Dwell Control for Prestolite 4 Cylinder
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) 45,000 volt coils. Adaptive dwell maintains peak energy throughout the entire RPM range, reducing misfires while improving engine performance Develops on average 4 times more available energy
