MSD Three Step Module Selector

The MSD Module Selectors allow you to choose two or three dif­ferent rpm limits that can be activated at different times.

With the addition of an RPM Activated Switch, you can use the Three 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.

• Set 3 RPM limits:
• Burnout rev limiter
• Launch rev limiter
• Top End rev Limiter
