Distance To Empty (Dte); Time To Empty (Tte) - UltraGauge EM Installation & Operation Manual

Distance To Empty (DTE)

DTE provides an estimate of the number of miles before the fuel tank is Empty based upon average miles per gallon.
UltraGauge uses either the vehicle's Fuel Level Sensor, if present via the OBDII, or it calculates the remaining fuel by
continuously tracking the amount of fuel used. See the Fuel Sender Section for more details.
With Fuel Tank Sensor:
When a sensor is present via OBDII, UltraGauge can determine when the tank is refilled and DTE will be updated
automatically. The distance to empty is determined by the current general average miles per gallon gauge; Average MPG, and
the number of gallons in the fuel tank. When a fuel level sensor is present, the DTE Gauge Range is 0 to 9999.9 miles
Without Fuel Tank Sensor:
When a fuel level sensor is not available, or the Fuel Sender Mode is set to Disabled, UltraGauge has no ability to sense the
actual fuel level. It is necessary that UltraGauge be informed each time the tank is filled. To do this, select MENU

Fuel fill up or by holding the UP key for 3 seconds. UltraGauge then assumes that the tank has been filled and
Menu ..
contains the number of gallons/liters specified under MENU
Selecting MENU
NOTE: DTE is determined by the fuel level and the average MPG. This average MPG is the "general" MPG
If Distance traveled is less than 0.1 miles or Gallons Used is less than 0.01 Gallons, UltraGauge will assume an MPG Average of 5
MPG.
NOTE: Selecting MENU
NOTE: When a fuel level sensor setting is set to Disabled or Smart, the distance to empty can become negative and the range is
-9999.9 to 9999.9 miles. A negative number indicates the number of miles traveled or gallons used since the estimated remaining
fuel reached zero gallons. There is always an amount of fuel in the tank and in the system that the vehicle's fuel level sensor
cannot detect. Hence it is likely that the vehicle can travel several miles beyond the point that DTE becomes zero.
NOTE: Do not rely on this gauge until you have become comfortable with the accuracy of UltraGauge.

Time To Empty (TTE)

TTE provides an estimate of the number of hours and minutes remaining before the fuel tank is Empty and is based upon
Average Gallons/Hour gauge. UltraGauge uses either the vehicle's Fuel Level Sensor, if present, or it calculates the remaining
fuel by continuously tracking the amount of fuel used. See the Fuel Sender Section for more details.
Zeroing the Average Gallons/Hour gauge restarts TTE. Average G/H is zeroed by selecting:

With Fuel Tank Sensor:
When a sensor is present, UltraGauge can determine when the tank is refilled and TTE/DTE will be updated automatically. The
Time to empty is determined by the average fuel use and the number of gallons in the fuel tank. When a fuel level sensor is
present, the TTE Gauge Range is 0 to 999 hours and 59 minutes.
Without Fuel Tank Sensor:
When a fuel level sensor is not available, or the Fuel Sender Mode is set to Disabled, UltraGauge has no ability to sense the
actual fuel level. It is necessary that UltraGauge be informed each time the tank is filled. To do this, select MENU


Selecting MENU
NOTE: When a fuel level sensor setting is set to Disabled or Smart, Time to Empty can become negative and the range is -99.59 to
999.59 hours:mins. A negative number indicates the elapsed time since the estimated remaining fuel reached zero gallons. There is
always an amount of fuel in the tank and in the system that the vehicle's fuel level sensor cannot detect. Hence it is likely that the vehicle
can travel several miles beyond the point that TTE becomes zero.
NOTE: Do not rely on this gauge until you have become comfortable with the accuracy of UltraGauge.
NOTE: The alarm for this gauge is set in hours and fractions of hours, not Hours and minutes. A setting of 0.5 is 30 minutes.
