The Fuel Level gauge indicates the number of remaining gallons/liters in the fuel tank. This value is determined one of two
ways, depending on the Fuel Sender Mode Setting. When the Fuel Sender Mode is set to Disabled or Smart, the fuel level is
calculated based upon fuel used. When the Fuel Sender Mode is set to Enabled, the fuel level is calculated directly from the
fuel tank sensor.
When the Fuel Sender Mode is set to Disabled, it is necessary to inform UltraGauge manually that the tank has been filled.
This is done via the menu system by selecting MENU
Fuel Menu ..
Fuel fill up. This can also be accomplished by
pressing and holding the UP key for three seconds while UltraGauge is showing the Main Gauge display. Once Fuel Fill-Up is
done, the Fuel Level, TTE and DTE will adjust.
To determine if your vehicle supports a fuel level sensor, select MENU
Fuel Menu ..
Fuel Sender Mode. If the
response is “No Fuel Sensor Found”, no sensor is available via the OBDII. Otherwise, the vehicle supports the sensor and
UltraGauge will automatically use this sensor to determine the Fuel Level.
Some vehicles incorrectly report the support of a fuel level sensor. For those vehicles the reported fuel level will be frozen or
inaccurate. In this situation, the use of the fuel level sensor must be disabled. To disable the fuel level sensor, select MENU
Fuel Menu ..
Fuel Sender Mode. Then select Disabled.
NOTE:
There can be more fuel than indicated when the sensor reports 100% full, and there can be a reserve of fuel when the sensor
reports 0 gallons remaining. When the fuel level is calculated, fuel level can report a negative number indicating that you have
used more fuel than your reported fuel tank size. This is normal as there is always an unreported reserve. Vehicle Tank sensors
are also notoriously inaccurate by as much as +-3 gallons. It is recommended to set the Fuel Sender setting to either disabled or
Smart. See the Fuel Sender Setting section for additional details
