Fuel Related Gauges - Best Practices
« on: April 16, 2012, 03:58:31 PM »
Looking for a simple "Best Practice" step-by-step to getting the most accurate fuel related gauges on the UltraGauge as the manual kind of jumps around a bit.

1) Set Engine Size - Check your owner's manual and enter select: MENU->Vehicle Setup->Set Engine Size and enter that information.

2) Set Fuel Tank Size - Check your owner's manual and select: MENU->Vehicle Setup->Set Fuel Tank Size and enter the information.

3) Calibrate Distance - Plan a route, preferably straight, that's at least 2.5 miles (4 kilometers).  Align front tire with first mile marker.  Reset the trip gauges by going to: MENU->Gauge Menu->Zero All Trip.  Travel at least 2.5 miles and align front tire with mile marker.  Select: MENU->Vehicle Setup->Calibration->Calibrate Distance and enter the distance traveled (the further you travel and the faster the speed the better the accuracy of the calibration).

4) Calibrate MPG - Ensure Distance Calibration has been done.  Fill up fuel tank.  Hold UP key to cause UltraGauge to recognize fill-up.  Zero the Average MPG by selecting: MENU->Gauge/Page Menu->Zero Avg MPG.  At the next fuel fill-up, note the number of gallons used (pumped) from pump display or receipt.  Select: MENU->Vehicle Setup->Calibration->Calibrate MPG/Fuel and enter fuel used.  Press MENU when complete to set and save calibration.  use the same fuel station and pump for best results.  You can do this over several fill-ups to improve accuracy.  The Calibration Factor will be displayed at the bottom of the screen.  Make note of this as it can be used directly to set the calibration should you ever need to clear your configuration.

If your vehicle does NOT have a Fuel Tank Sensor you should enter the fuel used at each fill-up to improve the accuracy of gauges like Distance To Empty (DTE).  I have been bouncing the Average MPG numbers against the car's tripometer and number of gallons pumped to be sure that it's close.

My question is, once I'm confident that it's all working okay, can I get in the habit of resetting my Trip Gauges at each fill-up?

Wonder if one should use the exact fuel tank size?  I've fudged a bit, and shorted by about 1/2 a gallon...
