Ignition timing is always a compromise of power because one setting will not produce optimum combustion throughout the entire rpm range of your engine. The Pro Mag Retard Control allows you to compensate for these changes by retarding the timing at exactly when you want, and how much you want. The Timing Retard features two separate channels so it can be used with single or dual Pro Mag systems. The amount of retard is set with MSD retard modules and up to 30� (with MSD Pro-Cap) can be removed. The retard is activated with two activation wires and can be controlled manually, through a timer or rpm activated switch. There is a built-in tach output terminal that can be used to trigger an rpm activated switch plus there is an LED that indicates when the retard for each channel is activated. The Pro Mag Timing Retard is supplied with retard modules for 1� - 10�, vibration mounts and d harnesses.
