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.
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 analogue 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 permits installation in even the most crowded engine compartment.
