MSD Electronic Engine Governor

Installing a rev limiter on your commercial vehicle will prove beneficial by protecting the engine from overrev damage. When the selected rpm limit is reached, special circuitry drops the spark to different cylinders, then fires that same cylinder on the next cycle. The Electronic Engine Governor is designed to be used in applications such as delivery trucks that operate under 5,000 rpm. The rpm limit is easily adjusted with plug-in modules and is supplied with 3,600, 3,800 and 4,000 rpm modules. For use with 4, 6 and 8 cylinder engines.
