    3-Step Module Selector
    For Use with:
  • MSD Soft Touch Rev Control
  • MSD Ignition Control with RPM Module Socket

    This selector allows you to have (3) different rpm limits:
  • First is a burn out limit to control wheel speed
  • Second is a starting line RPM limit for more consistant launches and quicker 60-foot times
  • Third is a top end rpm limit to protect your motor from overev.

    The starting line limit can be controlled by the Trans Brake, Line Lock or a Clutch Pedal Mounted switches. This requires the use of (2) buttons: one for the burn out limit and one for the starting line limit.

    Note: rpm or retard modules sold separately.
  • Set 3 RPM limits:
  • Burnout rev limiter

    Precise RPM Control

    MSD offers 2 and 3-step RPM Controllers that allow you to control RPM limits for consistent and steady RPM levels that result in firm launches.
