nitrous help (bogs and spitters)

corvette8189 · 10-13-2009, 12:13 AM

well i installed my nx nitrous kit. and went out to test it.
i have a tps, fuel saftey, msd window switch. when i activate it, it just bogs and spitters and doesnt work and runs better without it. it also does it when not even at full throttle. i check all solenoids and tps switch. everything looks good and seems to work.
do i have some wiring wronge or is something not working right.
any help is appreicated

with the key in the on position i armed the system and the tps lit up, then put the pedal to the floor and it tures red whitch its suppose to. also when at idle and i arm the nitrous, the idle dips a tad like 50 rpms and when off goes back up. i dont know if its just a load or not

Which TPS unit do you have?

Have you adjusted the FPSS?

Have you made sure that all wires have good connections and proper grounds?

Have you verified that you got a good bottle fill?

tps is from nitous express

how do you adjust the fpss, i bought the kit used and it was already hooked up to the fuel solenoid so i just hooked it up.

all wires good and grounded.

yes bottle is full

With the kit armed ( You will need a way to activate the kit....I'd run a jumper so you bypass the window switch and TPS ) and activated * This will need to be done in 10sec bursts * take the nozzle or at least the fuel hose going to the nozzle and put it in a bucket. As you have the kit activated and the fuel is flowing you will adjust the setscrew on the top of the FPSS Clockwise until you see the fuel begin to sputter out of the nozzle or hose. Once you see the fuel sputtering then you will turn the screw half to 3/4 turn counter-clock wise and then the FPSS should be set to the vehicle properly.

have you checked the spark plugs? what did you gap them to?

hotjohnnyls1 · 10-14-2009, 10:35 PM

yeha make sure they are gapped correctly i had the same problem

Sofls1 · 10-14-2009, 10:59 PM

Sounds like your only spraying fuel. I'm willing to bet that its your fuel pressure safety switch. I would try adjusting it like Chris noted, or just wire it out. (for testing purposes only)

spark plugs gapped at 35

the part i dont understand is when i arm the nitrous it just turns on, when not in full throttle or in my window switch spot. and it drops my idle a bit when armed.

finally fixed it. it was the msd window switch.

What was wrong with the widow switch? Was it a digital or normal window switch. The reason I ask is because I'm having problems myself with possibly my window switch.

corvette8189 · 10-16-2009, 04:26 PM

it was the one u stick the pills in it. i believe its the 8956 msd window switch. just bypass it and go see if it works.
