I have seen videos sayin somthing about setting there 2 step wrong or whatever so I googled maxima 2 step and it said it had something to do with launch control. I am very interested in thi but when I search I don't see a straight explanation. Can someone clear this up for me and point to where I can get this if needed. Mods are headers only

 

you need a greedy emanage ultimate piggy back to do this. I'm sure there are other piggy backs as well.
Basically you set it up so that when you mat the pedal at the tree at the drag strip, the car will go to the maximum wanted rpm's that you know will not spin the tires. Then when the brake is released or a switch is flipped the car will launch without spinning the tires then will go to WOT
