    After application, and for maximum adhesion, allow the adhesive to set for 1 hour before use.  When attaching the UltraGauge mounting bracket to the mount head, it is not necessary to fully seat the bracket. Slide the bracket onto the "T" notch until the bracket will no longer slide easily.

  • Page 14: Start-Up & Configuration

    Start-up & Configuration When UltraGauge is first attached to the vehicle’s OBD-II connector it is immediately powered, as the vehicle’s OBD-II connector is always powered. Once connected UltraGauge will begin scanning the interface to determine the vehicle’s protocol. The vehicles ignition must be in the RUN position in order for UltraGauge to communicate with the vehicle’s Electronic Control Module (ECM).

  • Page 15: Other Setup Considerations

    There are three “ignition on” or Power On detection modes. When the ignition is switched to OFF, UltraGauge enters a low power mode where the display is powered off. When the ignition is switched from OFF to RUN, UltraGauge will detect this in 1-6 seconds and power back on.
  • Page 16 If you wish to move UltraGauge to another vehicle to use the trouble code functions, this can be done with no regard to configuration or calibration. The only exceptions are if force protocol has been set or 9141 optimization has been executed. These configuration items will need to be reset prior to moving to a different vehicle.

    Outside Ambient Air Temperature (ºC) UltraGauge Voltage Gauges in Blue are new for UltraGauge EM plus 1.4 *There are two possible sets of Lambda values returned by the ECM. One is current based and the other voltage based. While there is only one set of sensors and it would seem that a given vehicle would support either voltage or current, it is possible for the ECM to support both.

    Volumetric efficiency is a measure of how fully your vehicle can fill its cylinders with the fuel/air mixture on the intake stroke. For example, a vehicle with a VE of 50% is able to fill its cylinder with 50% of it potential. UltraGauge uses several engine sensors to determine the VE dynamically.

  • Page 36: Partial Tank Fill Up

    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.

  • Page 39: Vehicle Setup

    Vehicle Setup .. Calibration.. Calibrate MPG/Fuel This calibration is used to fine-tune UltraGauge to accurately measure fuel usage. This calibration is critical, especially for vehicles which use a MAP sensor, diesels and alternative fuels.  For vehicles that use a MAP sensor*, see the menu section on Adaptive Volumetric Efficiency before proceeding.

  • Page 40: Reset Mpg/Fuel Cal

    If you chose to travel several mile markers, then enter in the number of miles actually driven, for example, 3.000 miles. NOTE: Unplugging UltraGauge after calibration will not cause loss of calibration. NOTE: Using the vehicle’s odometer to perform this calibration is pointless since the odometer and UltraGauge receive distance information from the same source; the vehicle’s ECM.

  • Page 41: Ve Enable (Map Only)

    If after calibration, it is found that the MPG results are still not accurate enough, the VE RPM value can be further adjusted. If UltraGauge reports less fuel used than actual, reduce the VE RPM by 200 and repeat Calibration. Likewise, if UltraGauge reports more fuel used than actual, increase the VE RPM by 200.

    ECM 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, mode 0 can result in battery drain on 2000 and newer GM vehicles and vehicles which use the CAN protocol.

  • Page 46: Power Off Detect Mode

    For most vehicles UltraGauge will correctly detect when the ignition has been switched to OFF with the default setting. Should UltraGauge remain on beyond 15 seconds after exiting the vehicle, use this setting to change the method UltraGauge uses to detect that the ignition is in the OFF position.

  • Page 47: Bat Low Threshold

    Alternatively consider Power off detect modes 3 or 5. A side effect of increasing the value is that UltraGauge will remain on for a longer period of time after the ignition is switched to Off.

  • Page 48: Force Mpg Sensor

    Normally Auto is the correct and desirable setting. Please do not change this setting unless you must. Certain vehicles misreport the presence of sensors. When this happens, UltraGauge is not able to calculate the fuel usage and various mileage gauges may display “Err” or nonsensical values. All other gauges will display correctly. This setting is used to override the reported sensor present and forces UltraGauge to use the selected sensor.

  • Page 49: Display Settings

    0% Brightness The sensitivity to the Ambient light can be adjusted via the Ambient Sensitivity menu setting. This setting allows UltraGauge to better adjust the Backlight brightness depending on the Vehicle’s ambient light. For example, vehicles with tinted windows or with smaller windows will have overall lower light levels and an increase in sensitivity would be recommended.

  • Page 50: Backlite Max Brightness

    Vehicles with tinted, smaller or fewer windows will have lesser ambient light levels. This setting allows UltraGauge to be tailored to your vehicle’s light levels. This setting has a range of from 0-100, with 100 being the most sensitive.

  • Page 51: Alarms

    Each gauge can have a high and low alarm. Each Low and High Alarm can individually be enabled and the value of each high and low alarm threshold can be individually set. UltraGauge continually compares real-time gauge values to each of the alarm values. If the real-time value is greater than the high alarm or less than the low alarm, an alarm is initiated.

Pending codes are potential issues discovered by the Vehicle’s ECM. These discovered issues are placed in the pending category and monitored by the ECM.

  • Page 56: Emissions Readiness

    This is a continuous real-time test. The OBDII standard requires that the ECM always report the status as ready. As such there is no point reporting the Fuel System monitor status, and it is not supported by UltraGauge Misfire Engine cylinder misfires test.
  • Page 57 However, it does not mean that the results of the test failed, only that the test completed or not. Once a test completes, and the test is marked “Ready”, the test may have passed or failed. If the test failed there will likely be trouble codes posted. Note that UltraGauge is simply the messenger, relaying information from the vehicle’s ECM, and has no influence or impact upon the tests.

  • Page 58: Gas Engine

    As a result, if the ECM is busy running the monitors the status may change in real time. Pressing any key will halt the readiness status monitoring and exit to the Menu. The following potential readiness test status is presented by UltraGauge:...
