keydiver launch control removal

My car has the keydiver chip with a 4500 rpm launch control which was functioning properly. It has always been too low of an rev for a decent launch, and I never "no lift to shift", so while doing the pedal assembly repair, I thought I'd go ahead and cut the wire between the ecu and the clutch switch. Now it won't rev past 4500 at all. My thinking is that I need to either ground out or supply power to the ecu side of that wire, but which is it? And if I power it, 5v or 12v? Maybe I should just weasel up under the passenger side of the dash and reconnect the wire that you have to cut to install the pedal wire? /ubbthreads/images/graemlins/dunno.gif

the wire from the clutch switch goes to another wire above the switch. I think without it hooked up, it always thinks your clutch is depressed.

Good deal, now how many do I need to buy for us to hang out. /ubbthreads/images/graemlins/rofl.gif
 

If you want to hang out, you just have to say something. Now that the clutch is finally right on my car, I will drive it anywhere.

on my old keydriver I was able to select the 2step rev limit with the clutch pedal. I dont remember the exact process, but it might help ya out to research it.

The Launch rpm was adjustable via the Gas pedal with the Key On Engine OFF.

I could run mine all the way up to 6k with pedal taps, it illuminated one light on the factory boost gauge for every 500 rpm increment.
