Is there any reason Launch Control documentation was left out?

This is all I've found on it so far, and I'm not clear which maps it's active on:

When you let go of the volume-down button, the ignition advance will be ramped back in and you will pick up another 50-60lbft of torque over the next 1/2 second. You better have traction when you do this.
