WARNING

TO AVOID DAMAGING THE DISPLAY, NEVER PUSH ON THE SCREEN.

DO NOT PUSH ON THE SCREEN WHILE PLUGGING IN THE HARNESS,
AS YOU WILL DAMAGE THE UNIT.

THE CONTROL BUTTON CAN ONLY BE MOVED UP, DOWN, AND
INWARD. NONE OF THOSE DIRECTIONS IN COMBINATION FOR IT
WILL DAMAGE THE GAUGE AND VOID THE WARRANTY

The Nitrous Express Bottle Volume Display Controller gauge will control many aspects of your nitrous oxide system. This
device is the world’s first all-in-one full color controller with integrated display. No need for a laptop computer or additional
boxes; it’s all in the 2-1/16th inch gauge. The Bottle Volume Display Controller combines microprocessor controls & with a
real world color user interface. The Bottle Volume Display Controller gauge (PN: 15534) will display how much nitrous
you have remaining in the bottle, your bottle pressure, and control a heater to maintain your target bottle pressure. You
will be able to program the gauge in seconds after reading the instructions. Take the time and read all the instructions
before beginning your installation. Failure or damage may occur if all the wiring and programming are not done properly.

Push the control button in.

This is the Safety Cutoff setup screen where you can program the gauge to cut your nitrous
system. (Requires a relay). Because some input types may have signal spikes that can cause
a false trigger, each cut-off has a delay time to help filter these. The gauge requires the trigger
condition to be present for longer than the set delay time before it will trigger a cut off.

SCROLL DOWN:

This screen allows you to select which sensor will trigger a cutoff [Enabled]. Disabling a sensor
prevents it from triggering the cutoff.

SCROLL DOWN:

This is your LOW bottle pressure set point. If your bottle pressure drops below this point, your
cutoff relay will be activated. Push the control button in (text will change to blue) and make
adjustments up or down to fit your needs. Once your low side pressure is set, push the control
button in to save it.

SCROLL DOWN:

This is your HI bottle pressure set point. If your bottle pressure rises above this point your
cutoff relay will be activated. Push the control button in (text will change to blue) and make
adjustments up or down to fit your needs. Once your hi side pressure is set, push the control
button in to save it.

SCROLL DOWN:

This is the delay for the nitrous pressure. This determines how long the bottle pressure must
be above you hi set point or below your low set point before activating the cutoff relay. Push
the control button in to adjust this up or down. Once your delay is set, push the control button
in again to save it.

SCROLL DOWN:

This will allow you to set the same settings for sensor #2 as you did for the nitrous bottle pressure. Once you have
finished setting your cutoff selections, scroll to the Exit and push the control button in to return to the Exit and Save
screen.

Pushing the control button in at this time will save and return you to the Main Viewing Screen.

Note: Before calibrating the gauge you must have correctly configured the gauge and have a
full tank connected to your system

display the true level in your tank until you have calibrated it. If the tank shows empty but it is not, continue to use the
system as you would have before.

Press the control button and scroll to Reset Full Bottle. Press the control button in and the gauge
will now be set to full and will return to the main screen. Now use you nitrous system as you would
normally.

Note: Because EMPTY is subjective, different users will have different levels at which they consider
the bottle to be empty. The gauge is programmed with a default empty level and may not accurately

Once you reach the level that you consider your empty level, go to the bottle level configuration
screen, select Set Empty and press the control button in to save. NOW every time you refill
your bottle you must press the control button and scroll to Reset Full Bottle. Press the control
button in and the gauge will now be set to full, and you will return to the main screen. Now use
you nitrous system as you would normally.

REMINDER: every time you put a full bottle into the car, you must tell the gauge you did so.

Important:

will display an hourglass ICON. DO NOT power off the gauge while the hourglass ICON is present. Once the gauge
detects that no further solenoid activity has occurred, it updates the usage log and turns off the ICON. At this point it is
safe to power off the gauge. Failure to do this will impact the accuracy of the gauge.

Each time the gauge detects that your solenoids are activated, it begins to track your nitrous usage and

Here are some tips for moving around and reprogramming your gauge.

• On the main viewing screen, push the control button up will change your screen to different views. This allows
you to watch your sensors as just like it’s another gauge. EXP. While tuning N/A you could watch air/fuel as if
your Bottle Volume gauge was just an air/fuel gauge. (sensor must be programmed and plugged into an Air/Fuel
source).

• On the main viewing screen, push the control button down and your gauge will dim. Helpful when driving at night
to lesson the brightness of your Bottle Volume gauge. Push down again to return to bright.

• You do not have to go through each programming screen just to program 1 screen. You can enter configure
mode and can jump to which ever mode you need to adjust. Same goes within a configure mode you can jump to
the parameter you want to adjust. When finish just exit out then Exit/Save and you are done.

• Your heaters default mode is disabled. You will always need to enable your heater for it to work and heat your
bottle, when you power down your gauge the heater will turn off.

• You may see some coloration though the bar graph areas. This is called banding and is normal and will not hurt
the gauge in any way.

• When you have a cutout trip you will see a large RED area around the area that caused the trip. You will need to
push the control button in, to reset this feature. This allows you to see what caused the nitrous system to turn off.

• Throughout your programming the term scaling is used. This deals with the bar under your numerical readouts.

• Make sure the ground wire to the Bottle Volume gauge is by itself on a good clean area, (meaning no other wires

are connected to it or in the general area). Especially hi amp cycling wires like solenoids etc.

• NEVER PUSH ON THE SCREEN WHEN INSERTING ELECTICAL SOCKET, DAMAGE TO THE SCREEN WILL

HAPPEN.

• NEVER CONNECT THE POWER AND GROUND BACKWARDS. THIS WILL FRY YOUR GAUGE.
