How does it work? What's it for? <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />

 

I want to know also?

 

Think of it as a "Window of Opportunity". Ties into the PCM for RPMs, you can set it for when you want the N2O system to start and stop spraying. For example, if you have a M6, it would be very bad to bounce off the rev limiter while spraying, so you can have the window switch stop spraying the N2O at say, 6200rpms, if your rev limiter is 6400.

 

This sounds like a good idea obviously. Where do you mount it? Where do you cut into the PCM? Does anyone have a link for this?
