2. Ride the bike for a precisely known distance, preferably for at least 10 miles for best
accuracy. Just as for method #1, a GPS receiver is a good way to go here although highway
markings may also work well.
3. Enter the speed calibration screen (see instructions above) and use the upper and lower
buttons to adjust the speed calibration value (%) until the trip odometer reading (shown on
the first display line) matches the correct distance ridden.
After adjusting the speed calibration, press both button at the same time to advance to the fuel
calibration screen.
Fuel calibration mode
The fuel calibration factor is adjustable between 1 and 255%. Although the nominal setting of
100% will give the theoretically correct reading, a value of 110% was found to given the best
accuracy on two tested V-Rods (’03 VRSCA, ’06 VRSCR). This is the value programmed in the V-
Gauge Lite as delivered.

– The fuel calibration screen. Note that the fuel usage (compare to Figure 8) is also shown
with the fuel calibration value (%).
The following procedure is used to adjust the fuel use calibration factor.
1. Fill the fuel tank as near as reasonably possible to the top of the filler neck.
2. Place the V-Gauge Lite in the fuel management screen (see Figure 8) and reset the fuel use
to zero by pressing and holding the upper button.
3. Wait until the next time the bike needs to be refueled.
4. Fill the fuel tank to as full as reasonably possible, again.
5. Enter the fuel calibration screen (see instructions above) and use the upper and lower
buttons to adjust the fuel calibration value (%) until the number of gallons shown (or liters,
in metric mode) matches as near as possible what the pump said was just dispensed into the
tank.
