Pertronix Digital Rev Limiter

Pertronix new digital rev limiter. Simple wire in. Fully adjustable. Can be used on all engines. Adjusts in the thousands with 100 rpm steps This Pertronix Flamethrower Digital Rev Limiter takes out individual ignition strikes a little at a time to safely prevent dangerous over-revving, and to prevent plug fouling. It s easily and quickly adjustable in increments of 100 RPM. Excellent Unit!;This digital micro-controller based unit provides a much greater accuracy (+/-0.01%) over analog systems. There is no need for old resistor style pills or chips, our easy to use rotary switches adjust the RPM limit to an ultra fine resolution of 100 RPMs. Random spark stealing method provides superior control of rev limits and a rapid response time to over rev limit events, preventing engine failure. Once the established RPM limit is reached, random spark stealing starts within one spark, reducing plug fouling common with repetitive stealing type limiters. Rev limiters come with multiple analog filters and one digital filter to prevent coil noise interference from affecting the established rev limit. Installation is a snap with a four wire hookup and easy to understand instructions. The rev limiter s small size (3 X 2 1/2 X 1 1/2 ) permits installation in even the most crowded engine compartment
