PerTronix 91581 Ignitor II Adaptive Dwell Control for Prestolite 8 Cylinder

PerTronix 91581 Ignitor II Adaptive Dwell Control for Prestolite 8 Cylinder
- Adaptive dwell maintains peak energy throughout the entire RPM range, reducing misfires while improving engine performance
- Develops on average 4 times more available energy between 3000 and 5000 RPM, and 2 times more available plug voltage
- Compensates for inherent electronic delay by adjusting the spark timing throughout the entire RPM range
- Synchronized peak current and spark timing reduces heat build-up
- Senses startup and develops more energy for quicker, easier starting
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.
