Description

  • RPM Controls Three Step Module Selector, RPM Controls Three Step Module Selector; Allows You To Choose Two Or Three Different RPM Limits That Can Be Activated At Different Times;, Set 3 RPM limits: Burnout/Launch/Top End rev limiters, The MSD module selectors allow you to choose two or three different rpm limits that can be activated at different times.
  • With this ability, the possibilities are endless.
  • As an example, we'll use a drag car with a three 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 you're on the starting line, you can activate the second limit through the clutch or trans switch.
  • This provides a steady and consistent rpm for firm hole shots every time.
  • When no modules are selected, the remaining high limit is active to protect the engine in the event of driveline failure.
  • The two step works the same, but only with two different limits.
  • 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., RPM Module Selector, Engine RPM Limiter.
