Other Setup Considerations
UltraGauge is pre-configured for the most compatible configuration. However, there may be situations that may require special
configuration. The following suggests configuration settings that may be necessary depending upon your vehicle as well as other
configuration setting you should be aware of.
Imperial versus Metric Units
There is no setting to switch between Imperial and Metric units. UltraGauge supports both simultaneously. This allows either or both to
be displayed. For example, if you wish to display KPH and MPH, simply select KPH and MPH from the gauge selection menu and
assign them to positions on the display. By default, UltraGauge is shipped with a pre-selection of imperial gauges. Use the gauge
selection menu to select the desired gauges with the desired units.
Ignition on Detection
There are three “ignition on” or Power On detection modes. When the ignition is switched to OFF, UltraGauge enters a low power
mode where the display is powered off. When the ignition is switched from OFF to RUN, UltraGauge will detect this in 1-6 seconds and
power back on. If UltraGauge fails to power back on, please see the in the “UltraGauge setup..” section.
Power on Detect mode
Ignition off Detection
If after the vehicle’s ignition switch is set to OFF, UltraGauge remains on, please see the
in the “
Power off Detect mode
section.

Mileage Gauges
During the scanning and gauge discovery process, UltraGauge determines the most accurate means to calculate fuel usage based upon the
various vehicle sensors available. Normally no intervention or configuration is necessary. However, in very rare cases, some vehicles
may mis-report the presence of a particular sensor which UltraGauge will then attempt to use to calculate the various mileage gauges,
such as Instantaneous MPG, Average MPG, Gallons/Hour, etc. When this issue is present, many of the mileage gauges may display
“Err”. Other gauges such as engine temperature, RPM, MPH, etc., will display correctly. This is common on many large Diesel Ford
trucks. If seen, please see the section for more information
Force MPG Sensor
Impaired or odd behavior of vehicle systems
If after installing UltraGauge your vehicle is experiencing odd behavior, such as various dash lights have become lit, factory gauges stop
working, vehicle fails to shift, hard shifting, etc. Please see the following section:
Force Protocol
MPG Accuracy
For best results, UltraGauge should be calibrated for both distance and fuel measurement. See the following section:
Calibration..
Diesel vehicles must perform fuel calibration otherwise MPG and fuel gauges will be dramatically inaccurate.
Vehicles which use a
Manifold Absolute Pressure (MAP) sensor instead of a Mass Air Flow (MAF) sensor should also see the following section:
VE Enable
and .
(MAP only) VE RPM (MAP only)
To determine which sensor your vehicle uses see this section
