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 youre 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 consistent tire temperatures. These limits are adjustable with MSDs plug-in modules. No rpm modules are supplied.
