Hardcore Launching
Serious racers know that to get the hardest and most consistent launches you need a transbrake. Even if you have a higher stall torque converter, you'll never get full flash stall off the line by just foot-braking. The LaunchMax for 2011-2017 Mustang is a simple splice-in device that allows you to activate the trans-brake function with a push of a momentary switch (not included).

All Digital
The JMS LaunchMax has no moving parts, making it extremely fast and durable. Since its all self-contained there are no external relays or other components to fail. It doesn't affect the line pressure or shift logic so that it can be easily used in conjunction with a tune.

Installation
Installation is straight-forward and simple. You just splice in the wires from the LaunchMax unit into the ECU harness and wire an activation switch (Not Included) wherever you'd like it. You can activate the trans brake function with any switch that provides 12-volt power.
