If you have a high performance race engine with locked out timing, cranking the engine can really put a strain on the starter and flywheel. This compact controller provides a retard that automatically retards the timing during cranking to ease the pressure. The Starter Saver wires into your ignition system and can be programmed to retard the timing 10° or 20° during cranking and is deactivated once the engine reaches over 800 rpm (If the rpm's drop below 500 it will activate again). The Starter Saver receives the trigger signal through an MSD Crank Trigger pickup or the distributor's magnetic pickup. This control has a very accurate pickup compensation circuit resulting in rock steady timing throughout the entire rpm range of your engine. There is also an LED that illuminates with each trigger signal to confirm operation and the circuitry is completely potted in a polyurethane compound for extreme vibration resistance.
