A large digital LED display makes it easier than ever to see the rev limiter setting when dialing it in using the laser etched rotary dials on the face of the unit. MSD’s smoothest rev limiter yet! The rotary dials are also used to set cylinder select for 4, 6, and 8 cylinder engines, and to adjust the built-in start retard providing options of 0⁰, 10⁰ or 20⁰ of timing retard for quick starts.
