Im not 100% sure what it exactly does..someone give me a lil more detailed description of what it does

 

I'm a newb, but I believe it's a control that engages nitrous flow at a certain rpm, then shuts it if off at a certain rpm....

 

1ScrudeDude- That is correct, all the window switch does is allows the nitrous system to operate in a specific rpm window. That window is created by plugging rpm chips into the box. This allows the user to raise, lower, enlarge, or shrink the window. Keep in mind though, that you will still need to use some type of wide open throttle switch, wether it is a mechanical switch, or a electronic TPS switch.

 

NX Window switch does not use chips, all programmed by a laptop. And then later in life upgrade the same unit a progressive controller.

So that means if i was to set my window from 3000 to 6400 rpm for example..even though i still would be holding the nit button still shuts off at 6400 rpms until it changes gears and then repeats

 

Changing gears doesn't affect the system's activation/deactivation. If the WOT switch is activated, the system will activate as long as the rpm's are in the window regardless of wether or not you're changing gears.
