I have a 6 spd car and i have my nitrous setup on a WOT switch...Is there anyway to setup the nitrous so that when its turned on it doesnt spray in 1st or 2nd gear but when i hit 3rd gear it sprays....I also have it hooked up to a mallory 685 box and set to spray at 3000-6000rpm

Thanks

 

Your going to need a "any gear" lock out window switch like this one


or this one



You can still use the mallory to retard the timing, just use one of these as the window switch.

 

I have the nitrous outlet switch and it works great..
