Based on the superior design of the MSD 6CT, the 6CT PRO adds a fully potted housing and a quick-reset high-RPM recall to MSD's line of circle track ignitions. A large digital LED display and laser-etched rotary dials make it easy to dial in the rev limiter, cylinder select, and start retard, while rev limiting is microprocessor-controlled for a smooth feel that won't upset the chassis charging into turns. The unit records the highest RPM turned during the race, recallable on the LED display and quickly reset with a remote, momentary switch.
