The ETC Inc. High-Range Rev Limiter is a unique control device that has been designed to work with all Mallory Magnetos. Models are also available for the Vertex Standard Internal Coil and External Coil Magnetos. Other types of ignition are available on request.

RPM is preset at the factory (your choice) and can not be altered. A push to test switch is provided to test unit at a lower RPM (2,000 minimum). Limiting is accomplished by causing a programmed misfire sequence of the engine when the RPM exceeds the preset point.

It does not short the mag or alter the magneto performance in any way. It is completely safe with a supercharged engine and will not cause backfire or crossfire in the cap which causes catastrophic engine damage. This unit has been designed using the newest linear, digital, and power devices. The device weighs only eight ounces and is small in size at 4.0” x 2.25” x 1.80” with two additional one-inch mounting flanges on each side. It has a mounting plate with holes for grommets and/or DZUS fasteners. This rev limiter has been designed to operate in the presence of mechanical vibrations and high electrostatic ignition noise generated by magneto ignition systems.
