As I progress with my project and move further along. I've started playing with the 2 step/launch control features. I seem to be having an issue getting it to build anymore then 2 or 3 psi at the launch. At the given RPM that I've tried (Higher and lower) Thats all I can get it to produce. I know what I need is infront of me, but lack the understanding of the settings (No mater how much I read) an could use alittle bit of an explanation.

Here are my settings. It would build 15psi on a 68mm turbo

It was honestly way too much for drag radials and probably would have been better off on maybe 10psi and 5000rpm, but it sounded great and was a lot of fun.

how do you guys have your wiring connected? cruise control switch?

Thanks Shaniac. Gives me an idea of what I wasnt playing with. It will get me in the right direction.

As for how? Right now mine is wired to a push button. It will either go to the clutch switch or starter interlock switch. Soon

I had launch control/flat shift connected to the stock clutch switch using a 1/4" spade connector. I grounded the other side of the switch. I also put a toggle switch between the launch/flat wire so I could disable it from the clutch for normal driving. It makes heel-toe driving impossible.
FWIW, I have since found that "add fuel" doesn't do a whole lot and takes away some of that quintessential launch control pop and flame. I've left it off on friends cars and it's a lot more dramatic.

I did wire the cruise control switch to activate "pit lane limiter". This is rolling antilag to boil the turbo from a roll. It works great but is hell on exhaust gaskets. It doesn't use the same parameters as launch control and is much more violent and loud. I wired it to the "resume" side of the switch. I would just turn cruise off when I planned on using it and had no issues. The button still worked for cruise control also.
