PERTRONIX DIGITAL REV LIMITER - PTX-600

This digital microcontroller 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.

Works with any 4, 6 or 8 cylinder engine using points, OEM electronic (GM HEI, Ford, Chrysler) or aftermarket inductive type ignition systems.
