FUEL MENU ..
Partial Tank fill up
MENU  Fuel Menu..  Partial Tank fill up
It is always recommended to fill-up your fuel tank completely and then use MENU
 Fuel Menu ..  Fuel fill up. However,
Partial tank fill ups are supported. Simply select MENU
 Fuel Menu ..  Partial Tank fill up, and then enter the amount of
fuel added to the fuel tank. To simplify entry, UltraGauge will always display an initial partial fill up amount that is 60% of the
maximum amount that could be added, rounded down to the whole gallon. UltraGauge will only allow a maximum amount of
fuel to be entered that corresponds to the amount of fuel missing from the tank. If you pump more fuel than UltraGauge will
allow, this likely means that the Fuel Tank Size setting has been set too low.
After entering the amount of fuel, UltraGauge will briefly display the current fuel level at the bottom of the screen.
Using Partial Fill-up is not recommended since small errors in the amount of added fuel, the tank size, and calculated fuel
amounts are cumulative with each partial fill-up. This can result in inaccurate values of Fuel Level and DTE. For this reason, it
is recommended to perform a tank fill up periodically to reduce any accumulated error.
Empty Fuel Tank
MENU  Fuel Menu..  Empty Fuel Tank
Informs UltraGauge that the Fuel Tank is empty. This affects the Fuel Level, TTE and DTE gauges. Typically Empty Fuel
Tank is used along with Partial Tank fill up to set the initial amount of fuel in the fuel tank.
Fuel fill up
MENU  Fuel Menu..  Fuel fill up
Use this menu item to inform UltraGauge that the tank has been completely filled. Once filled, UltraGauge assumes the amount
of fuel in the tank is equal to the fuel tank size. Once initiated, UltraGauge will then adjust the Fuel Level, TTE and DTE
gauges accordingly.
This menu item is an alternative to the quick Tank fill up initiated by pressing and holding the UP key until the Fuel fill up is
triggered, while in the main display.
This menu item is only necessary for vehicles not reporting a fuel tank sensor. For vehicles with an OBDII available fuel tank
sensor that is operating in smart mode, tank fill up is automatic and there should be no need to use this menu item. However,
Fuel fill up can be used and will result in the equivalent of an automatic tank fill up.
Level Sender Mode
MENU  Fuel Menu ..  Level Sender Mode
UltraGauge automatically determines if the vehicle supports a fuel level sensor via the OBDII. If no sensor is available, the
message “No Fuel Sensor Found” will be displayed when MENU
 Fuel Menu ..  Level Sender Mode is selected. If not
present, see the Disabled setting below for additional details. Please note that all vehicles have a fuel level sensor, however, not
all vehicles make the sensor available via the OBDII.
If a Fuel Level Sensor is present, this menu item will offer three options:
Disabled
When disabled, the fuel sensor, if present, is ignored and UltraGauge continually calculates the amount of fuel used. The result
is used by the Fuel Level, TTE and DTE gauges. In this mode it is necessary to inform UltraGauge each time the tank is filled.
To do so, hold the UP key until a “Tank Full” message appears. Alternatively, select MENU
 Fuel Menu ..  Fuel fill up
or optionally, MENU
 Fuel Menu ..Partial Tank Fill Up can be selected and amount of fuel pumped can be entered. After
signaling the addition of fuel, the Fuel level, TTE and DTE will be recalculated.
