No2 Cuts Off?

**Cam** · 10-31-2007, 01:08 PM

I have a dynotune 2 stage window switch and a dry kit. It looks like everything is wired correct and i have all the options set as needed. I am using the tps signal as the wot switch. When i hit wot the noid opens and then closes. Can anyone help?

Never looked at a schematic for a setup using the TPS as WOT, but I'd imagine that its got something to do with the signal that the TPS is providing.

How long does it stay open for?

are you using a relay? the dynotune (actually trick performance products makes it. i have one) cannot take over 1 amp. so, it cannot ground the solenoids directly. you use it to ground the relay instead.

It's the same one your talkn about. With the bottle turned off I can turn my throttle to wide open and it triggers the relay and opens the noid but when i test drive it it kicks on then seems to sputter and quit.

siphon tube in the correct location when the bottle is mounted?

I Have The Bottle Mounted Verticle With The Valve Opening To The Rear

You can feel it hit hard as soon as 3k rpms and themn it dies

Vertical would have one assume the bottle is mounted straight up and down? Then you say the valve opens to the rear? I'm real confused.

We need to know what make your bottle is and how the feed is oriented.

If it just dies and never comes back tho, one would assume the noids are closing for some reason... which means ur wiring would come into question.

Are your grounds SOLID and using the correct gauge wire?

maybe the WOT switch moves off of the TB and causes it to shut off. i've had that happen. the screws came loose.

the bottle is sitting up and the valve opening is facing the rear of the car. the nitrouse sprays at wot but when im driving and the nitro kicks on i have a burst of power then no power. It feels like the throttle body closes once the maf feels the spray.

is it sitting like this? the nipple the line screws to needs to be facing towards the front of the vehicle

The kit is form HSW and it tells me that it should be reverse from your settup. Its says that the burst valve sould be faceing the front of the vehicle. Could it be that i have my nozzle to close to the maf sensor? Its in the neck of the SLP lid just befor the maf. I took the lid off and set my window switch at 000rpms. With the engine not running i turned the thottle body to wide open and everything seems to work fine, it sprays until i let off the throttle. I set the window switch back at 030rpms and set the tps then take it for a test but same thing happened, hits hard at 3k rpm for a split second then the power falls off instantly.

well, i'm at a loss without being able to witness it. if you are close to me here in florida, maybe we can meet up.

**Cam** · 11-03-2007, 11:56 AM

Its about a 5hr drive form here. I live about an hour west of Tallahassee.
Thanks for the help though.

Yep, siphon tube faces the same side as the outlet on the HSW bottles.

Good luck man, I don't know what else to tell ya. Hope you're able to find it.
