Non driven wheel speed was the issue. Thanks for the quick reply fixed my issue completely

[Speed activated launch control. S15 g4+]

I was out messing around with launch control in my s14 with the link s15 g4+ plug and play.

 I was trying to set it up in the 2D setting. For some reason I can only get it to work when the car is moving not completely stopped. 

I noticed that as soon as I'm not moving di 5 goes inactive and the border around the the speed display turns red. I assume that's the issue but can't figure out how to force it to stay active. It's like the the input shuts off as soon as the car is at 0 wheel speed. I've read that link wants you to use a none drive wheel speed input. But all I have is the sensor in the transmission.
