Fuel Level Detection
UltraGauge automatically determines if the vehicle supports a fuel level sensor via the OBDII. If no sensor is available,
the message “No Fuel Sensor Found” will be displayed when
Settings
Fuel Settings
Fuel Level Detection is
selected. If not present, see the Disabled setting below for additional details. Please note that all vehicles have a fuel
level sensor, however, not all vehicles make the sensor available via the OBDII.
If a Fuel Level Sensor is present, this menu item will offer three options:
Manual
When disabled, the fuel sensor, if present, is ignored and UltraGauge continually calculates the amount of fuel used.
The result is used by the
Fuel Level, TTE
and
DTE
gauges. In this mode it is necessary to inform UltraGauge each
time the tank is filled. To do so, select use
from the Gauge screen or optionally,
can be selected and amount of fuel pumped can be entered.
After signaling the
addition of fuel, the
Fuel level, TTE
and
DTE
will be recalculated.
Fuel Sensor
When Enabled, fuel level is determined from the vehicles fuel level sensor. In this mode UltraGauge continually
monitors the fuel level sensor and updates the Fuel Level, TTE, DTE, and Fuel Level % gauges. As a result Fuel
Fill-ups are automatic.
Note:
As fuel sloshes around in the tank, from driving around corners, going up or down hills, braking or accelerating, the
Level Sender Mode can provide inaccurate readings. UltraGauge attempts to smooth the results to lessen this affect. However,
for some vehicles with significant sender variation, this issue may be seen in the form of DTE and Fuel Level variation. To
avoid this issue, use the Smart Level Sender Mode setting.
Auto-Fill
Auto-Fill determines the fuel level by continually calculating the fuel used. It also monitors the fuel sender to
determine if a tank fill-up has occurred. There are two user configurable thresholds that are used to determine when a
Tank fill-up has occurred; Low Threshold and Full Threshold. When the fuel level falls below the low threshold, the
auto-fill function becomes armed. When the tank is filled and the fuel level exceeds the Full Threshold, UltraGauge
triggers an Automatic Fill-up event. When this happens UltraGauge assumes the tank has been topped off and
contains the amount of fuel equal to the fuel tank size. The Fuel Level, TTE and DTE gauges will adjust
automatically.
By default the Low Threshold is set to 50% and the full threshold is set to 98%. Setting the Low Threshold too high
may cause a false Auto-Fill event to trigger as a result of gas sloshing around in the fuel tank.
NOTE: When changing the mode from
Manual
or
Fuel Sensor
to
Auto-Fill
, UltraGauge will automatically estimate the existing
fuel in the fuel tank by using the output of the fuel tank sensor. This is best performed while not moving and on level ground.
This one-time estimate will alter the Fuel Level, TTE and DTE gauges only.
