Dyna Shift Minder The Dyna Shift Minder System is the ultimate in racing shift light products. The Shift Minder System consists of an attractive billet aluminum Shift Light and the Shift Minder control module. The Dyna Shift Light is a hallmark of the quality, reliability, and innovation that Dynatek strives to include in every product. Machined billet aluminum with an attractive black and gold anodize finish contribute to a custom rugged appearance. The Dyna Shift Light is more than the most attractive shift light on the market, it is also track proven to be the most reliable. Repeated track testing on Pro Stock drag vehicles has proven the Dyna Shift Light to be capable of withstanding the rigors of racing with highly extended bulb life compared to other products. The Dyna Shift Light is activated by the Dyna Shift Minder control module. The Shift Minder control module is a small electronic box which monitors the engine rpm in order to trigger the Shift Light at precisely the right time. The Shift Minder control module has been designed with extremely accurate circuitry to insure triggering accuracy to better than 1%. The Shift Minder control module is adjustable to switch at any of 64 different rpm settings with a 125 rpm increment between settings. The Shift Minder control module is self contained and requires no additional parts for rpm switch point selection.
