Set Engine Size
Sets the engine size in liters. This is only important for vehicles that do not have a Mass Air Flow Sensor (MAF). For these
vehicles, it is imperative that the engine size be set, otherwise the Mileage Gauges will be inaccurate. The MPG calculation and
calibration is also dependent on this setting.
Often the vehicle manufacturer will round the engine size to the nearest tenth for badging and labeling. For example, 5.56L
becomes 5.6L. Check the specifications section of the vehicle’s owner manual for actual engine size.

Set Fuel Tank Size
Sets the fuel tank size in Gallons. This is used to calculate the fuel level and Distance to Empty Gauges.
If the tank size for your vehicle is specified only in liters, then use the following equation to determine gallons:

Calibrate MPG/Fuel
MENU
Vehicle Setup ..
Calibration..
Calibrate MPG/Fuel
This calibration is used to fine-tune UltraGauge to accurately measure fuel usage. This calibration is critical, especially for vehicles
which use a MAP sensor, diesels and alternative fuels.
For vehicles that use a MAP sensor*, see the menu section on Adaptive Volumetric Efficiency before proceeding.
Prior to this calibration, consider performing the distance calibration. See the section:
Calibration can not be performed if less than 4 liters or 1 gallon have been used.
The gauges that depend on fuel usage will not be accurate until this calibration is complete.
Calibration Procedure:
1.
Fill up the fuel tank.
2.
Set the ignition to the RUN position (Engine Off)
3.
Press and hold the UP key to cause UltraGauge to recognize the fill-up
4.
Zero the Average MPG. MENU --> Gauge/Page Menu .. --> Zero Ave MPG, G/H.
5.
Exit the Menu system
6.
Drive until its time for the next fuel fill-up.
7.
At the next fuel fill-up, fill the fuel tank and note the number of gallons/liters used (pumped). (Always use
the same fuel station and the same fuel pump)
8.
Set the ignition to the RUN position (engine off)
9.
Press and hold the UP key to cause UltraGauge to recognize the fill-up
10.
Select MENU --> Vehicle Setup.. --> Calibration.. --> Calibrate MPG/Fuel, and change the value displayed
to the amount of fuel recorded in step #7. Press MENU when complete to set and save the calibration.
11.
Exit the Menu system the cal is complete
Congratulations, you have successfully calibrated UltraGauge to your vehicle.
Alternatively, to improve accuracy, record and add the fuel used (pumped) over several fill-ups to improve accuracy.
Multi-fill-up Calibration:
1.
Fill up the fuel tank.
2.
Set the ignition to the RUN position (Engine Off)
3.
Press and hold the UP key to cause UltraGauge to recognize the fill-up
4.
Zero the Average MPG. MENU --> Gauge/Page Menu .. --> Zero Ave MPG, G/H.
5.
Exit the Menu system
6.
Drive until its time for the next fuel fill-up.
