MSD 6CT Ignition Control

Rev limiting is controlled via microprocessor making it so smooth the chassis is virtually undisturbed when charging into turns. 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. As an added bonus the LED display can be used as a live tach or will display your racecars battery voltage. The unit records the highest RPM your engine turned during the race which can be easily recalled on the LED display as well.
