The 1M861 B14 bin already has a limited launch rev limit capability built in. You can't set the speed, as it is fixed at 0, and the hysteresis is fixed at 500 rpm, but you can set the following bin locations to enable it:
E5CA = Launch rev limit in 50 rpm steps (ex: 60 = 3000 rpm)
E5CC = 0
As soon as the car starts to move (speed > 0), this rev limit is disabled and the engine will rev above this set point. The 500 rpm hysteresis is pretty large so if you set the limit at 3000, the injectors will be cut at 3000, but won't start injecting again until rpm drops to 2500, or speed gets above 0.
