i just bought the kit off a friend. the kit worked fine and i put it into my car hooked evcerything up and flipped the switch the light on the box was green. its a dry safe kit so it only sprays at full throttle. but the light was green i fliped it a couple times to make sure it was staying green. it all was good. the car was never running and the bottle was empty and closed. my friend accidentaly hit the button on the zex box which i think is the rerset button and the light turned red. i turned it off disconected the battery and ground and stuff cjecked all the fuses and turned it back on the light is still red. i tryed to hold it and i t is still red. idk could it be because the bottle is empty but the light was green when the bottle was closed. i dont know how to get the light back to green can sopmebody please help

 

im pretty sure you need to do something with the throttle, so that when you are at 100% throttle the light will turn green, otherwise it should be off.

 

you need to disconnect the box's power source from where you have it.

make sure the key is off when you reconnect it. then turn your key on, press the button on, the light should be red. then press it, i believe it should blink, then hold the throttle open slowly to the max. you may have to do it a couple times then it will turn green.


if i remember correctly.

you can go to zex.com and the instructions are on thier site

STEP 8: Program Activation Switch & Check Vacuum and Pressure Lines
Now that you have completed the installation and wiring of your nitrous kit, one of the final
steps is to program the Activation Switch and check the vacuum and pressure lines. To program
the Activation Switch, turn the vehicle's ignition on, but do not start the engine. Turn the nitrous
arming switch to the "ON" position. Go to the Nitrous Management Unit (NMU) and locate the
push-button switch. Depress, then release, the push-button switch. Observe the NMU's
Operation Light. At this point, it should be RED. This RED light informs you that the NMU's
Activation Switch is in learn mode. Return to the driver's seat and depress the accelerator pedal
to the floor, holding it there for ten seconds. Release the accelerator pedal and go back to the
NMU and observe the Operation Light. At this point, the light should be flashing continuously
from RED to GREEN to OFF. This is the NMU's way of telling you that it has successfully
learned the voltage curve of your engine's throttle position sensor. Go back to the driver's
compartment and turn off the system's arming switch, then turn it back on. Go back to the NMU
and observe the Operation Light. It should be solid GREEN at this point. This informs you that
the system is armed and ready to activate at wide-open throttle. Return to the driver’s seat and
depress and release the accelerator pedal several times. You should hear the solenoid click each
time you reach wide-open throttle. At this point, your Activation Switch is fully programmed
and ready for use. If you ever transfer your nitrous system to another vehicle, perform this same
procedure on the new vehicle to "relearn" the NMU's Activation Switch.
