To help achieve consistency, MSD has incorporated an adjustable low rpm stage into a Three Step Module Selector. This allows you to make adjustments in 100 rpm increments from the driver's seat. The Launch Control Module features a shielded harness for increased protection against EMI so it can be mounted within easy reach of the driver. This plugs into any MSD rev limiter chip socket and expands its functionality to be THREE sockets in one.

The Launch Control features two other rpm limits; one for top end over-rev protection and another to use during the burnout to achieve consistent tire temperatures. These limits are adjustable with MSD's plug-in modules. RPM modules not included.
