Module Selectors

The Two and Three Step Module Selectors give you the ability to switch between different rpm limits with a Soft Touch Rev Control, you can connect it to an MSD Timing Control and use it to select retard rates. Either way you have a variety of functions when connected to an MSD MC-2 Ignition or Multi-Step Retard. With this selection capability these devices can be used to perform a variety of functions.

When the Three Step is connected to the built-in rev control of an MC ignition, you have the choice of three rev limits with the flip of a switch. One limit can be used during the burnout to keep tire temperatures consistent between each run. A second rev limit can be activated on the starting line to keep the engine rpm at a steady level. When the green light comes on and the switch is released the rpm revs up resulting in quick and consistent launches every time. The engine is still protected by the third limit from over revving during the race. The Two Step operates the same way, but only has tow modules for launch and over rev protection.

Requires MSD modules, not included
