To help drag racers achieve even more consistency, MSD engineers have 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 way, as track conditions change while you're waiting in the staging lanes you can easily compensate the launch rpm.

The Launch Control also features two other rpm limits; one for top end overrev protection and another to use during the burnout to achieve consistant tire temperatures. These limits are adjustable with MSD's plug-in modules. No tpm modules are supplied.
