Reset Distance CAL
Resets the Distance Calibration factor to the factory default of 1.000. Use this to restore the calibration factor if the
Distance Calibration is performed improperly.

Set Max Engine Torque

Set Max Engine Torque
Sets the maximum engine torque for the target vehicle. This parameter must first be configured prior to using Brake 1
or Torque 1 gauges. The maximum torque is a common parameter that can be found by searching the internet for the
engine specification for your vehicle. The torque is commonly specified as a Torque @ a particular RPM. For example,
200 ft.lbs @ 3200 RPM. The torque may be entered in Foot-Pounds (ft.lbs) or Newton Meters (Nm).

Set Engine Efficiency

Vehicle Settings
Set Engine Efficiency
Sets the estimated operating efficiency of the engine. This parameter is used by the Brake2 or Torque2 gauges.
Break2 and Torque2 are derived based on the amount of energy being consumed by the engine and the engine’s
efficiency. By default the efficiency is assumed to be 24%. This means that only 24% of the energy contained in the
fuel actually produces power or torque output. 24% is a good average for typical modern vehicles. This value can be
adjusted if more specific information is available.

Power On/Off Detection
For compatibility reasons, UltraGauge supports three modes to detect that the ignition is in the RUN position or that the
engine is running. Normally, when UltraGauge detects the ignition-on/engine-running condition, UltraGauge exits its
low power mode and begins normal operation
Read OBDII Sensor (Mode 0) (Not recommended)
This optional mode is primarily for vehicles which use the 9141 or KWP2000 protocols. This mode
continually queries the ECU to determine if it is powered and active. If a response is received, UltraGauge
assumes that the ignition is on. This mode can also be used when mode 2 fails to cause UltraGauge to wake.
However, this mode can result in battery drain on 2000 and newer GM vehicles and vehicles which use the
CAN protocol. See the Battery Drain discussion for more detail.
Monitor OBDII Bus Activity (Mode 1) (Not recommended)
This mode actively monitors the communication bus for activity. If found, UltraGauge will then attempt to
communicate with the ECU. If the ECU responds, the ignition is assumed to be in the RUN position. If set,
this mode is ignored for vehicles with 9141 and KWP2000 protocols, and the Read OBDII Sensor mode is
forced. In very rare cases, certain vehicles may exhibit battery drain when this mode is selected. If battery
drain should occur, use the Monitor Battery Voltage mode. See the Battery Drain discussion for more detail.
Monitor Battery Voltage (Mode 2) (Recommended)
(Default mode) This mode can be used for all vehicles and protocols and is the most compatible. This mode
detects the engine running and wakes UltraGauge. It accomplishes engine run detection by detecting elevated
battery voltage caused by an active Alternator. The Battery high voltage threshold used by this mode is by
default set to 13.2 volts. This voltage threshold can be adjusted via the Bat High Threshold
Menu item. The
weakness of this mode is that simply turning the ignition to the RUN position will not wake UltraGauge.
Pressing the Adaptor’s button will always cause the Adapter to wake. However, once on, the Adapter will begin
immediately looking to see if Power Off Detection is satisfied. See the Power Off Detection Mode.
