Help with launch control
I have a DIYPNP, everything is set up to use launch control, but here is the kicker. The launch control works when the clutch is depressed and when it isn't depressed, but it will not work with the clutch depressed and it is in gear. I tried unhooking the neutral safety switch, when I do that it doesn't work at all.
Any suggestions?

there is nothing that tells the ms that its in 1st gear. im guessing your clutch switch is janky. its not supposed to work both depressed and not depressed
thats what the switch is for. otherwise you'll just have really low rev limit
also I think your tps might have something to do with this

Well what is weird is if the car is in gear it will rev to the normal 7200 rev limiter.
I have the tps unhooked, I will try and climb up under the dash and change the clutch switch.

You have to disconnect the safety switch that goes to the transmission
It is for the cruse control, if it pops out of gear it disables it.. with the MSPNP way of wiring the sensors for the traction control, it will not enable it until you unplug those wires
from the manual for the PNP:

from the manual for the PNP:
The launch control is based on a rev limiter. This is configured from the Extended → Launch Control dialog. Often the best way to control this is with the stock clutch switch which opens/closes a circuit based on the clutch pedal position. Note that often this circuit also runs through the neutral safety switch on manual transmission vehicles. This means that if you turn launch control on using the stock clutch switch, it will activate when the transmission is in neutral or when you push down the clutch. So when the trans is in neutral, you'll have a launch control rev limiter. When you push in the clutch and put the trans into first gear, you'll also have a launch control rev limiter (which is when you want it) every time after you first put the car in gear and take your foot off the clutch. When you have the launch control active, the rev limits drop to the limits specified on the launch control screen, letting you rev the engine up to a fixed RPM that you can adjust. When you release the switch, the rev limit is removed and you take off… nice and controlled.

Vladi Vlad nailed that **** on the head... pics to follow... the spring for the clutch switch to the ECU was broke in 4 positions and was stuck. So I took the switch apart, went to the hardware store got a new spring, put some dielectric grease in it and put it back together. It works now, and yes, the neutral switch on the transmission is disconnected.
Video of launch control will be posted soon
Thanks guys.
