WARNINGS
Information in this document is subject to change without notice. Ultra-Gauge.com reserves the right to change or improve its products
and to make changes in the content without obligation to notify any person or organization of such changes, additions or improvements.
Always visit Ultra-Gauge.com for the latest updates concerning the installation, use and operation of this product.
Failure to avoid the following potentially hazardous situations can result in an accident or
collision resulting in death or serious injury
INSTALLATION WARNINGS
When installing UltraGauge in your vehicle, place UltraGauge so that it does not obstruct the driver’s view of the road or ability
to operate the vehicle.
Extreme care must be taken when routing the OBD II cable. Avoid routing and installing in such a fashion that the cable can
interfere with any of the foot controls, steering wheel, or other vehicle controls, or represent an entry or exit hazard to the driver.
Always secure excess or loose cable so that feet and hands do not become entangled.
The windshield mount or Velcro mount may not stay attached under all conditions. Do not mount UltraGauge where it will
become a distraction or hazard should it become detached.
Do not mount UltraGauge in an area that may interfere with the deployment of airbags. Consult your vehicles owner’s manual.
UltraGauge in rare circumstances may impair select vehicle systems. See the Forced Protocol section for more information and
resolution.
Tightening the windshield mount locking ring will result in increased force necessary to adjust the position of UltraGauge and if
over tightened may result in damage. The ring should be adjusted so that the ball swivel offers a very slight resistance to
movement.
OPERATION WARNINGS
Never attempt to operate UltraGauge controls while the vehicle is moving. Not only is this extremely hazardous, UltraGauge
stops performing mileage, distance and other calculations while the menu system is active.
Never become distracted by UltraGauge while driving.
Liability
The use of UltraGauge is at your own risk. Ultra-Gauge.com shall in no event be liable for any damages, whether direct or indirect,
special or general, consequential or incidental, arising from any loss claimed as a result of the use of UltraGauge.
Battery Warning
This product contains no batteries
Fuse Warning
This product is equipped with a fuse. The fuse is integrated in the male OBD-II connector and cannot be accessed or replaced.
This fuse provides protection against potential short-circuit conditions within UltraGauge and short-circuits introduced into the
cable.

Display Cleaning
The display has a polarizing film over the glass. This film is very easily scratched and damaged.
UltraGauge is shipped with a protective plastic film over the display to keep it clean. Many opt to leave the protective plastic film in
place to protect the display.
Unless the display is very dirty, avoid cleaning the display
The display can be cleaned, but requires extreme caution. We recommend a mild soap or 90% isopropyl alcohol as the cleaning agent.
Isopropyl alcohol has the advantage that it evaporates quickly and leaves no film behind. Only use a very soft cleaning tissue such as
toilet paper or facial tissue such as Kleenex. Use very light pressure when cleaning. Such soft tissue tends to leave fibrous debris
clinging to the display. Use a clean micro fiber cloth to lightly dust the surface. While dusting the surface blow against the surface to
wisk away the debris.

Display will remain on while in the menu system. Always exit the menu system when the ignition is in the OFF position.
Installation
The Basic installations steps are as follows:
1. Choose method of mounting; Custom, Hook & Loop, vertical, horizontal or windshield mount
2. Install the mount
3. Attach UltraGauge to the mount
4. Optionally coil extra cable near UltraGauge to allow UltraGauge to be disconnected from mount and conveniently
configured
5. Route the remainder of the cable such that it is tucked away and does not interfere with vehicle controls, such as steering,
wiper control, transmission shifter, turn signal, foot controls, and does not represent a hazard to vehicle entry or exit.
6. Turn the ignition to the RUN position. (The ignition has four positions: OFF, ACC, RUN & START. You do not need to
start the vehicle)
7. Connect the UltraGauge OBD II connector to the OBD II connector on the vehicle
8. UltraGauge will then determine the vehicle’s protocol and discover the available gauges.
Detailed Installation instructions
Choose method for mounting; Hook & Loop, vertical, horizontal or windshield mount. The Hook & Loop mount has the
advantage that it can be used to attach in areas less visible from outside the vehicle, reducing the risk of vandalism and theft.
The Hook & Loop mount is also less likely to lose attachment over time and is inherently less obstructive.
The windshield mount has the advantage that it typically positions UltraGauge in an area that is closer to the view of the road
and hence potentially represents less interruption to driving concentration. The windshield mount can also be attached to any
smooth surface and is therefore not limited to the windshield.
Hook & Loop
The hook and loop fastener, commonly known as Velcro™, is comprised of two halves, each is 1"x1.5". One half is attached to the back
of UltraGauge, as shown above. The 2nd half is attached to a surface inside the vehicle, such as the dash. The fastener may be used as-is
or trimmed in size or cut in to several pieces. Each half has an adhesive that can be applied to any clean, solid surface. The fastener is
an industrial strength Hook & Loop which can withstand temperatures as high as 250F (121C) without lifting or shearing from the
attached surface.
Width 1"
Length ~1.5"
Thickness mated 0.15"
Color Black
Temperature range -20F - 250F

____________________________________________________________________________________________
Page 11/63 UltraGauge™ EM User Manual www.ultra-gauge.com
Installation:
It is advisable to slightly radius or round the corners with scissors, as shown above. This will reduce the likelihood of lifting
The surface to which the fastener is attached must be clean, dry, and oil and grease free.
Apply only after the surface and the tape have reached a temperature range of 70F to 90F.
Avoid leaving the adhesive exposed for longer than 3 minutes after removing the protective backing.
The adhesive is pressure sensitive. Apply roughly 5lbs of force per square inch for 5 seconds.
After application, and for maximum adhesion, allow the adhesive to set for 1 hour before us
WARNING: Improper application of the Hook & Loop fastener may cause adhesive failure and result in damage to UltraGauge.
Impact damage is not covered by the warranty.
It is also possible to place slugs or washer behind the UP, DOWN and MENU keys such that pressing the front of UltraGauge
depresses the switches, thus effectively converting the switches to the front. Examples can be found on the UltraGauge forum.
Windshield Mount
Before selecting a mounting position, check state and local laws and ordinances to determine permissible mounting locations.
Generally the preferred and optimal location is the left lower corner of the windshield, as this location is the least obstructive,
generally closest to the OBD-II connector of the vehicle, semi-shaded, and is least visible from outside the vehicle. This
location also will not block the use of a windshield sun-shade
.
WARNING:
Do not leave UltraGauge exposed to extreme dash temperatures on hot days. Damage to the LCD can occur.
Remove UltraGauge from the dash when leaving the vehicle or use a sun shade protector.
Locking Ring : Over tightening the ring will lock the ball and attempted adjustments to the position of UltraGauge can result
in damage.
1. Before attaching the mount to the windshield, mold the neck of the windshield mount as necessary to the slope of your
windshield and for the desired position of UltraGauge.
Never attempt to mold the neck of the windshield mount by grasping the mounting bracket or UltraGauge.
Damage to UltraGauge and/or the mounting bracket may occur, as the neck while flexible is relatively rigid.
Clean the windshield mounting area. This is crucial as any grease, dust, dirt or moisture will ultimately cause the
attachment to fail. Make sure the surface is completely dry before
proceeding.
Make sure the Windshield Mount locking arm is fully released. Do not force
the arm. There are two release tabs as shown. Grip the release tabs with
your thumb and index finger, and pull the release tabs in the direction of
the arrows imprinted on the release arm. This will release the locking
arm.
Once released, move the locking arm towards the Windshield Mount’s
neck, as shown, to release the suction cup.
WARNING !

OBD-II
With the Windshield Mount’s release arm fully released, press the silicon
base firmly against the windshield, and press the Windshield mount’s
locking arm. It will “click” as it is pressed.
When it has reached the end of its travel it will become resistant to further
movement. Do not attempt to force the locking arm as only a few “clicks”
are necessary and excess force may damage the mount. The windshield
mount should now be firmly attached to the windshield. If not, it is likely
caused by the silicon base not being placed fully flat against the windshield.
Release the locking arm as described above and repeat.
Attach the Bracket to the windshield mount by aligning the large rectangular
opening of the bracket with the matching rectangular structure on the
windshield mount. Slide down to attach. Do not force. Slide until significant
resistance is felt. Note that it may be necessary to rotate the windshield
mount’s head 180 degrees.
Attach the mounting bracket to UltraGauge such that the bracket’s release arm
is at the top as shown in this diagram.
The windshield mount also includes a locking ring which should be only loosely tightened to lock the swivel’s position.
1. Remove and save the twist tie from
the cable. Now that UltraGauge is
mounted, form an 8” diameter loop
with the OBD-II cable near
UltraGauge. This loop will allow
UltraGauge to be removed from the
mount and configured rather than
attempting to configure UltraGauge
while it is held in the mount.
2. Locate the vehicle’s OBD-II connector. This connector is typically found
above the foot controls and below the steering column. See the diagram
below. In rare cases, the connector may be found in a similar location on
the passenger side or even in the vehicle’s console. To determine where
the OBD-II connector is located for your vehicle, please use the following
resource: https://obdclearinghouse.com/#
If your vehicle is not listed, check other like model years.
3. Once the OBD-II connector is located, route the OBD-II cable so that it does not block or interfere with foot controls. The
UltraGauge connector is a right-angle connector. This design limits the connector from protruding into the foot controls

____________________________________________________________________________________________
Page 13/63 UltraGauge™ EM User Manual www.ultra-gauge.com
area. Tuck the cable into gaps between the dash and surrounding structures. Route the cable under the dash such that it
will not hang down into the foot control area. Care should be taken not to route the cable near moving objects, such as
the hood release, emergency brake, brake release, foot controls and associated mechanisms. If appropriate, use the
twist tie to secure any excess cable.
4. Set the ignition to the RUN position, and plug the cable into the vehicle’s OBD-II connector.
Vertical and Horizontal mounts.
 The surface to which the fastener is attached must be clean, dry, and oil and grease free. Clean the surface, even if it appears
clean
 Apply only after the surface and the adhesive have reached a temperature range of 70F to 90F.
 Avoid leaving the adhesive exposed for longer than 3 minutes after removing the protective backing.
 The adhesive is pressure sensitive. Apply roughly 5lbs of force per square inch for 5 seconds. Work the surface to ensure all
areas of the adhesive are activated.
 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.
Once the bracket is in place, UltraGauge can be snapped into the bracket . 
Once removed from its protective bag, optional mounts cannot be returned for a refund. Because the adhesive performance is
customer installation dependent, the adhesive has no warranty.

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).
The ignition must remain in the RUN position during both scanning and gauge discover.
The scanning process typically completes in 1 to 6 seconds. As UltraGauge
scans it continues to print asterisks to the screen. If after 12 seconds
UltraGauge has not found the protocol in use, it is likely that the ignition is not
in the RUN position. If UltraGauge fails to detect the vehicle’s protocol,
UltraGauge will enter a low power mode after 2 minutes. In this mode the
Backlight is turned off. UltraGauge will stay in this mode until either the UP
or DOWN key is pressed.
When UltraGauge successfully determines the vehicle’s protocol, it replaces
“SCANNING” with the identified protoco
l. The possible Protocols are:
Protocol Manufacturer
J1850 VPM GM & Chrysler
FORD Early Ford
9141 Chrysler & Foreign
KWP 2000 Rare, various
11-bit CAN Most 2008 and newer
29-bit CAN Most 2008 & newer Honda, Volvo
Once the protocol is identified, UltraGauge will remember the protocol and
should UltraGauge become unplugged, it will try this protocol first.
UltraGauge will then begin the process of discovering the gauges supported by
the vehicle. Again, the ignition must remain in the RUN position during
discovery; otherwise UltraGauge will print “Comm Lost, restarting”.
Once complete, the number of discovered gauges is briefly displayed at the
bottom of the screen. If “Comm Lost, restarting” persists, please see the
Enhanced and Safe mode Gauge Discovery section.
If UltraGauge has yet to be configured, you will be prompted for your
vehicle’s engine and fuel tank size. Use the UP/DOWN keys to set the engine
and tank size. Press MENU to store each value.
Once the engine and tank size are entered, a warning screen is presented.
Press enter to continue
UltraGauge is now up and running
Pressing DOWN advances the screen to the next page of gauges.
By default, several gauges are pre-assigned to each page. Alternate gauges can
be selected via the menu system. The available gauges are described in the
GAUGES section.

Other Setup Considerations
UltraGauge is pre-configured for the most compatible configuration. However, there may be situations that may require special
configuration. The following suggests configuration settings that may be necessary depending upon your vehicle as well as other
configuration setting you should be aware of.
Imperial versus Metric Units
There is no setting to switch between Imperial and Metric units. UltraGauge supports both simultaneously. This allows either or both to
be displayed. For example, if you wish to display KPH and MPH, simply select KPH and MPH from the gauge selection menu and
assign them to positions on the display. By default, UltraGauge is shipped with a pre-selection of imperial gauges. Use the gauge
selection menu to select the desired gauges with the desired units.
Ignition on Detection
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. If UltraGauge fails to power back on, please see the in the “UltraGauge setup..” section.
Power on Detect mode
Ignition off Detection
If after the vehicle’s ignition switch is set to OFF, UltraGauge remains on, please see the
in the “ Power off Detect mode section. UltraGauge Setup..
Mileage Gauges
During the scanning and gauge discovery process, UltraGauge determines the most accurate means to calculate fuel usage based upon the
various vehicle sensors available. Normally no intervention or configuration is necessary. However, in very rare cases, some vehicles
may mis-report the presence of a particular sensor which UltraGauge will then attempt to use to calculate the various mileage gauges,
such as Instantaneous MPG, Average MPG, Gallons/Hour, etc. When this issue is present, many of the mileage gauges may display
“Err”. Other gauges such as engine temperature, RPM, MPH, etc., will display correctly. This is common on many large Diesel Ford
trucks. If seen, please see the section for more information
Force MPG Sensor
Impaired or odd behavior of vehicle systems
If after installing UltraGauge your vehicle is experiencing odd behavior, such as various dash lights have become lit, factory gauges stop
working, vehicle fails to shift, hard shifting, etc. Please see the following section:
Force Protocol
MPG Accuracy
For best results, UltraGauge should be calibrated for both distance and fuel measurement. See the following section: Calibration..
Diesel vehicles must perform fuel calibration otherwise MPG and fuel gauges will be dramatically inaccurate. Vehicles which use a
Manifold Absolute Pressure (MAP) sensor instead of a Mass Air Flow (MAF) sensor should also see the following section:
VE Enable
and . (MAP only) VE RPM (MAP only)
To determine which sensor your vehicle uses see this section : . Version
Alarms
Certain Alarms come pre-enabled while others are disabled. Please see: and Trouble Code Alarm. ALARMS..

Page 16/63 UltraGauge™ EM User Manual www.ultra-gauge.com
KWP/9141 Optimization
The rate at which the display updates for vehicles with the KWP2000 or 9141 protocol may be slower than desired. There is a
configuration setting which may allow the rate to be increased. See the following setting:
KWP/9141 Optimize
Enhanced and Safe mode Gauge Discovery
When UltraGauge is connected to the OBDII connector it begins scanning for the protocol supported. Once found UltraGauge then
discovers the available gauges. There are two discovery modes; Enhanced & Safe. By default Enhanced is selected and recommended.
If during the discovery process, with the ignition in the RUN position, the message “Comm lost, Restarting” is displayed, then press
DOWN when prompted to select Safe mode. UltraGauge will remember the mode selected. Once in Safe mode, the prompt will change
and pressing DOWN will return to Enhanced mode.
Injector Cutoff Detection
During de-acceleration, many vehicle manufacturers will turn off the fuel injectors to save fuel. UltraGauge can detect this and factor it
into the fuel usage calculations. Depending on your driving conditions, this may or may not have a significant effect on mileage results.
By default this feature is disabled. See the section for more information. This feature is not supported on Diesel vehicles
Injector Cutoff
Use in Multiple Vehicles
UltraGauge can be moved from vehicle to vehicle. UltraGauge will scan and detect the protocol of the target vehicle automatically.
UltraGauge accumulates distance and fuel usage data. When UltraGauge is moved to another vehicle the accumulated data will need to
be reset. Also, any unique configuration and calibration may need adjustment. For these reasons, it’s better to leave UltraGauge in one
vehicle.
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.
If you do wish to move to a new vehicle, reset the device using the restore defaults command:
Menu UltraGauge Setup … Restore ALL defaults.
This command will fully restore the device back to factory settings.
If things go wrong
UltraGauge can be reset and restored to the factory default settings. Should configuration changes result in an undesirable setup or
UltraGauge becomes impaired, please see the “ ” command
Restore ALL Defaults

OPERATION
Once operating, UltraGauge is automatic. NEVER use the menu system while driving. Not only is this hazardous, UltraGauge stops
performing all mileage, distance, and other calculations while the menu system is active. Always ensure the vehicle is not moving and
the ignition is in the RUN position, before using the menu system. Normally UltraGauge detects and automatically turns off the display
when the ignition is in the OFF position. However, this feature is not active while using the menu system. Always exit the menu when
the ignition is off otherwise the display and backlight will remain on, and may drain the battery if left in this state for many days.
INDICATORS
While configured to display 4 or 6 gauges per page, two indicators are displayed.
HEALTH INDICATOR
The Health indicator is a heart that beats roughly every second. As
long as the heart continues to beat, UltraGauge is functioning
normally.
LOOP INDICATOR
The Open/Closed loop indicator provides a visual indication of the
state of the vehicle’s fuel mixture control system. Closed loop is the
desired and nominal condition, and indicates that the vehicle’s
Engine Control Module (ECM) is using the vehicle’s Oxygen and
other sensors to set the real time fuel mixture.
An open loop will normally occur when the vehicle is cold, or when
the throttle is wide open, or when the engine is being used to decelerate the vehicle. If the loop remains open this indicates that
there is a problem with the overall fuel mixture system and the ECM is no longer able to determine the correct fuel mixture. In
this situation the ECM uses a static table to approximate the fuel mixture. In this state the fuel mixture will likely be too rich or
too lean. Continued open loop operation will likely result in a Trouble code. This indicator is not present on most Diesels.
Light Sensor
UltraGauge features a light sensor that is used to optionally automatically adjust the brightness of the display. During the day, the
display backlight will automatically adjust to maximum brightness, and to minimum brightness for night driving. It is important that the
light sensor window is not blocked as a result of installation. The Light Sensor Port is located on the front right side of UltraGauge, as
shown above. The backlighting function is fully configurable. See the Backlighting section for additional details.
CONTROLS
There are three controls used to setup, configure and control UltraGauge. The controls consist of the following three input keys which
are located on the back of UltraGauge.

GAUGE PAGES & ZONES
UltraGauge can display seven separate pages of gauges. Each page can independently be configured to display 4, 6 or 8 gauges. Gauges
are displayed by assigning a gauge to a particular zone. Zones are identified by a number; 1 through 8. Assigning a gauge to zone “1”,
places the gauge in the upper left hand corner, as shown below. Likewise, a gauge assigned to Zone “6”, places the gauge in the lower
right hand corner. Zones that are unused on a page are ignored, but still may be assigned should you wish to switch between 4, 6 or 8
gauges per page.
During normal operation, to advance to the next page of gauges press and hold the DOWN arrow key for 1 second. UltraGauge will emit
a tone when the page advance is recognized. Pressing DOWN on the last enabled page returns the display to page 1.

The set Refresh time applies to every page. This setting also affects the rate at which the Heart Beat indicator beats. Lowering
the refresh time, increases the heart beat rate and the rate at which gauges are updated. This setting is intended for vehicles with
the CAN protocol and is not recommended for KWP and 9141 protocols.
GAUGE ZONE ASSIGNMENT
To assign a gauge to a page and zone:
1.
select MENU Gauge/Page Menu ..  Select Gauge/Page .. Select Gauges  Select Page n Gauges
2. Use the UP & DOWN keys to Navigate to the desired Gauge. Press Next or Back to advance to the next group of gauges
3. While the cursor is positioned next to the desired gauge, Press MENU. This will cause the cursor to blink.
4. Pressing UP or DOWN will cause the Cursor to change to a number corresponding to Zones 1-8. You may also continue to
hold UP or DOWN and the zones will advance automatically.
5. When the desired Zone is displayed, Press MENU to assign the Gauge to that Zone. Once assigned the cursor will stop
blinking. It is not necessary to first individually unassign a gauge by changing from a zone number to “blank”, before making a
new assignment.
6. Repeat the operation for each desired Gauge.
Once a gauge has been assigned to a zone, it is saved. The UltraGauge configuration is stored in non-volatile memory so that it is
preserved through car start/stop cycles or when the unit is unplugged. The configuration remains until changed.
All the gauges can be unassigned, with the menu item:
MENU
 Gauge/Page Menu ..  Select Gauge/Page ..  Unassign All Gauges.
Once unassigned the Main Gauge screen will show no gauges, and will only show the loop indicator and heartbeat and the text: “No
Gauges Selected”. This will be true for each gauge page set to display 4 or 6 gauges. This will also be true on a gauge page basis if all
the zones of a page are unassigned manually as part of the gauge zone assignment process.

GAUGES
The total potential available gauges is summarized in Table 1 - Potential Available Gauges. The actual gauges available is always
vehicle dependent. Once the initial gauge discovery process is complete, the number of available gauges and the number including
metric gauges will be displayed; Gauges/Metric. To determine which specific gauges are available, select:
MENU Gauge/Page Menu .. Select Gauges..
 Select Page n Gauges
In general vehicle manufacturers are federally required to provide gauges that are specifically used in the determination of the fuel
mixture for emissions purposes. Typically older vehicles provide a minimum of gauges while newer vehicles support nearly all gauges.
