Brake Pressure Switch for launch control ???

[Adger Smith]

If you don't have some way to deactivate the brake pressure switch down track in theory it could activate the 2 step when you do any hard braking.( dumping, hard backing into, ect) Depending on when, where, and how you hit the brakes that activated the 2 step it could be said you were activating a down track stutter device. I would hate to have that discussion with NHRA Tech. Some sort of deactivation switch is the route that might be all around the best and safest.
