 MSD 8158 Pro Mag Six Shooter Module Selector

 These MSD Six Shooter module selectors give you the ability to retard the timing of each magneto six different times and rates. They plug directly into the MSD Pro Mag timing 

control and the retard rates are controlled by plug-in modules that are activated when 12 volts are applied to the corresponding channel through a pressure switch or timer. 

Specifically designed for MSD Pro Mag timing  controls, the MSD Six Shooter module selectors can also be used with other MSD timing controls.

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 2x2°, 3, 4, 5, 8°, vibration mounts
