Mine never started in neutral or drive(original auto car) to being with, and is exactly the same now with the brake switch wired to pin 104 for nlts. I think it goes to another chassis piece that controls the starter switch.
Anyway, it didn't work how I wanted. When you are at a stop and VSS reads 0mph, it goes to the stutterbox rpm, even if the NLTS rpm is lower. It only uses the NLTS limit rpm when the VSS is reading, and that was verified by revving in neutral while rolling and pressing the brake pedal.
Found a bug, too. When you uncheck the stutterbox "box" yet still have the NLTS checked, it will always be on the NLTS rpm limit while the vehicle is moving no matter if pin 104 sees ground or not. The only way it goes to the standard rev limit is if you are at a complete stop. Again, pin 104 doesn't change anything.
A brake switch activated stutterbox or having the NLTS work while the VSS reads 0 would make what I'm trying to do possible; immediately disengage the launch rev limit when you let off the brakes instead of waiting for the laggy VSS to read.
I'm half tempted to hook something up to spin the speedometer cable while at the track :p
