OK, just installed the Nitrous Outlet single nozzle kit with their digital window switch and a Timing Tuner. Used their wiring diagram for hooking up a system when using both the window switch and Timing Tuner. Programmed the window switch as per the instructions that came with it, and set it up to activate between 4000 and 6000. Did not make any adjustments on the Timing Tuner. For an initial test, I disconnected the nitrous and fuel lines at the nozzle and put them in an empty pop bottle, just in case. Well, the second I hit the arm switch both solenoids opened (thank god the lines were disconnected from the nozzle). I then disconnected the gray wire from the timing tuner, and with the key on/engine off and arm switch on used a tester to see if current was coming from the window switch. The second I touched the ground wire on the tester the solenoids opened again (scared the **** out of me), and now the window switch display won't come on. I hooked the gray wire from the timing tuner back up and the display still doesn't come up, and with the arm switch on it is trying to spray at an idle. Any suggestions? This is my first nitrous install, but I was VERY meticulous with the wiring and checked and double checked to make sure that everything was routed according to Nitrous Outlet's diagram. PLEASE HELP!!!!!

 

Fpss?

 

How would a fpss cause it to spray the second the arm switch was turned on?

 

Sorry i miss read your thread.

 

Its a wiring issue- Post up the schematic you used-
Something is shorting out the WS

 

Called up Nitro Dave's this afternoon. The problem seems to be an outdated and incorrect wiring diagram. They directed me to the correct diagram and are deleting the incorrect one.
