hey bru, got this?
MENU ->Vehicle Setup .. ->Calibration.. _-> Calibrate Distance
Use this menu item to calibrate all Distance Gauges. This calibration also directly affects the accuracy of all Speed, MPG and
DTE gauges. This calibration is especially necessary for vehicles which no longer have the stock wheels, tire sizes,
transmission, or rear-end differential.. This calibration will also compensate for inaccuracies in stock speed sensor and the
vehicle’s distance measurement system, as well as for tire wear.
To perform the distance calibration, reset the Trip Gauges and travel a known precise distance and then enter the known
distance. Often roads will have mile markers, but avoid roads that are not straight. Align the front end of the vehicle with a
mile marker, reset the Trip gauges, and then drive to the next mile marker, or to as many consecutive mile markets desired.
Generally more markers will improve accuracy. Stop the vehicle, aligning the front end to the final mile marker. Select
MENU -> Vehicle Setup .. -> Calibration.. ->Calibrate Distance, and change the value shown to the actual distance traveled.
When finished, press MENU to exit and permanently save the calibration. Once entered, UltraGauge will show the resulting
calibration factor at the bottom of the screen. Note that unplugging UltraGauge after calibration will not cause loss of
Perform this Calibration prior to all other calibrations.
Note: Using the vehicle’s odometer to perform this calibration is pointless since the odometer and UltraGauge receive distance
information from the same source.
