PerTronix Digital Rev Limiter
This digital microcontroller based unit provides a much greater accuracy (+/-0.01%) over analogue 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.
