MSD Two Step Module Selector

Two Step Module Selector

The MSD Module Selectors allow you to choose two dif­ferent rpm limits that can be activated at different times. With this ability, the possibilities are endless.

Overview:
As an example, we’ll use a drag car with a Two Step Module Selec­tor plugged into the rpm socket of a 7AL-2 Ignition. The different rpm modules are activated when 12 volts are applied to a corresponding wire. By connecting one wire to the line-lock circuit, one module will be activated during the burnout. This helps keep tire temperatures consistent. When the line-lock button is released, the limit turns off. When no modules are selected, the remaining high limit is active to protect the engine in the event of driveline failure. The Module Selectors can also be used with an MSD Timing Control. By plugging the Selector into a retard module socket, you can acti­vate different retard amounts at select times. This is a great feature for engines being upgraded to a multi-stage nitrous system. With the addition of an RPM Activated Switch, you can use the Two Step to activate a shift light at different rpm.The Module Selectors must be used with an MSD Soft Touch Rev Control or a Timing Controller with a high-speed retard module. No rpm or retard modules are supplied.
