Default problems with my NX kit.....help please :(

i was at the track the other day and i had a full bottle but my nitrous was not working. i have an NX wet kit with a bottle heater, fuel pressure safety switch and a bottle opener. this is my problem........i will arm my nitrous and then stomp on the gas, it will hit in one gear and then when i shift...nothing. its like it just dies. i have it set on a WOT switch


any ideas as to what could cause this? all my fuses and **** are working fine, i checked it all out.

chould be your fuel pressure is droping after you chage gears to low and your FPSW is cutting it off.

An easy way to check the fpss is to take a small L E D inside the car. Give it power from the arming switch, and then its ground connect to the relay side of your FPSS. light stays on your good. Something else to check, the wot switch, make sure at full throttle there is complete closure or contact. If it is pull you seat up a couple of motches, the launch could be setting you back in the seat just enough to turn the system off.

Our new dual window switch upgradedable to progressive system later in life and for the money you can not go wrong.

Ricky, your killing me. Need new switch, yes!

Not to disscount other input, the way I check a fpss is just jump it post to post with wire (same as removing) then try it. Depending on switch sometimes they are not set correctly from factory. A lot of guys don't use one because of erratic operation, I do and reccomend one.

When I first started using nitrous I had noting but problems with that switch. I took it out and watched fuel pressure! It worked for me.
