people with MSD two steps

[WADS56]

How do you guys have it wired. I want to set it at 4000 rpm with the clutch it for my launch. How do you set up the msd to disengage the first step on launch to be consistant all the time.
It's kind of hard to explain. I want to beable to go to the starting line, push in the clutch, and hold the gas to the floor on the rev limiter. Then when I launch I want the two step to disengage when I let up the clutch for the first time but not engage every time I shift.
