MSD Adjustable Timing Control – Part# 8680 – The MSD Adjustable Timing Control puts you in control of your ignition timing – from the driver’s seat! A dash mounted control knob allows you to adjust the ignition timing to compensate for changes in altitude, low octane gas, or heavy loads. For cars driven every day but raced occasionally on the weekends, this control is perfect. Increased fuel mileage and performance are just some of the benefits as the ignition timing can be advanced or retarded to prevent engine detonation.
The control knob mounts to the dash board for easy and accurate timing adjustments up to 15°. The Control can be used on 4, 6 and 8-cylinder engines and must be used with an MSD Ignition Control.
MSD Start/Retard Control – Part# 8982 – This timing control is the direct result of MSD being at the races and listening to what racers want. With the large number of engines running locked-out timing, racers wanted a simple way to retard the timing during cranking plus have a single stage of retard available for high rpm or nitrous.
The Start/Retard Control lets you choose either 10° or 25° of retard during cranking only. The timing will retard only while cranking and returns to the set mechanical timing once the engine starts and you release the key or until the engine reaches 1,300 rpm.
