How accurate is my main tank fuel gauge after installing TRAX 3™?
The accuracy of the main fuel gauge will not change. The TRAX 3™ computer
module is wired into the truck’s main wire harness, in between the main fuel
tank and the fuel gauge. The TRAX 3™ module monitors the level of fuel in the
main tank, and then sends that same information to the fuel gauge on the dash.
The stock in-dash fuel gauge displays the level of fuel in the main tank as it did
before installing the TRAX 3™ auxiliary fuel system.
How do I adjust the contrast and brightness of my screen?
The two buttons on the front of the TRAX 3™ LCD module can be used to
adjust the contrast and backlight of the LCD display.
Steps to adjust the contrast or backlight setting:
1. With the ignition in the ON position the TRAX 3™ module should be
operational. Press the RIGHT button on the front of the display until you
reach “LCD Adjust” screen. Select with the LEFT button.
2. Press the LEFT or RIGHT buttons to adjust the contrast or backlight
respectively.
3. To exit the “LCD Adjust” mode and save your settings, do not press any
more buttons; The display will automatically default back to the fuel level
screen in approximately 3 - 4 seconds.
I typically keep trucks for one or two years and then get a new
one. Do I need a new Transfer Flow auxiliary fuel system?
It depends on the truck you are buying. You may need to purchase a re-
installation kit.
Why do I see my fuel level percentage fluctuate ± 10% in the first
two minutes of operation?
The module is rapidly calculating the fuel level in each tank to determine the
accurate value.
