Operation
The PAGE button may be depressed to scroll through the available AEMnet channels;
an abbreviation of each channel name will be briefly displayed after each button press.
The inner numeric LEDs and outer ring LED display the currently selected channel
reading. Channels will only be present in the channel list if the corresponding AEMnet
device is presently connected to the bus, powered, and transmitting. Please
reference the AEMnet Channel description table further on in this document.
PAGE and PEAK buttons are located on the face of the gauge and are used to
perform various functions, described below.
Display or clear stored peak value
§Press the PEAK button; the peak (highest) reading of the currently selected
channel will be displayed and the outer LED will flash.
§The peak value will be retained across power cycles.
§While the peak value is being displayed, depress and hold the PEAK button for
three seconds until "CLr" appears to clear the peak values.
§This operation will clear the peak values of ALL channels.
Will be displayed to confirm the peak value has been reset
§The gauge will return to normal display mode a few seconds after the last button
press
Change channel display units US / SI (metric)
§The gauge should be in its normal display mode,
showing the current parameter reading.
§Depress and hold the PAGE button for three
seconds until US or SI appears.
§Press the PAGE button to toggle between US or SI
(metric) modes.
§This setting will apply to all channels EXCEPT
wideband O2 channels.
§The gauge will return to normal display mode a few
seconds after the last button press.
Change wideband O2 display units AFR / Lambda
§The gauge should be in its normal display mode, showing a
wideband/oxygen sensor channel reading.
§Depress and hold the PAGE button for three seconds until
US or SI appears.
§Press the PAGE button to toggle between AFR or Lambda
modes.
§This setting will apply to all wideband O2 channels.
§The gauge will return to normal display mode a few seconds
after the last button press.
Hide or show channels
If multiple AEMnet devices are present on the bus, the channel list can grow to be quite long, up to 62 channels. This can
make it time consuming to scroll through and find a specific channel to display. A hide/show feature is available to
remove infrequently viewed channels from the channel list.
§Depress both the PAGE and PEAK buttons to display "HidE" and begin selecting
which channels to hide/show in the channel list.
§Use the PAGE button to scroll through the channel list and the depress the PEAK
button to toggle between hide and show.
§The gauge will return to normal display mode a few seconds after the last button
press.
All outer LEDs illuminated = SHOW
All outer LEDs off = HIDE

Faceplate / Bezel Installation
The gauge kit is supplied assembled with a black faceplate and black bezel. An accessory kit is available (for purchase
through AEM dealers) which includes an optional silver bezel and white faceplate. Please reference the Optional
Accessories section earlier in the document for the appropriate part numbers.
The faceplate may be reversible, displaying alternative scalings on either side. Reference the Operation section of this
manual for details on how to switch the display mode when reversing the faceplate. Disassembly is required to change
the faceplate, flip/reverse the faceplate, or change the bezel of the gauge. The following diagram will provide
familiarization with the major components of the gauge prior to beginning the procedure.

Gauge Disassembly
STEP 1 - Remove the three assembly screws (8) using a #1 Phillips
head screwdriver. Separate the bezel (2) and cup (7) from the restof the
assembly. Ifyou have purchased the optional accessory kit, the silver
bezel may be replaced for the existing bezel atthis time
STEP 2 - Separate the PCB (11) fromthe remaining components
STEP 3 - Slide the lightguide (5) upward to remove it, the buttons may
fall outatthis time - take care notto lose them
STEP 4 - As you separate the remaining components, diffuser (4),
faceplate (3), lens (1), note the order in which they were assembled.
The faceplate (3) may now be reversed to display an alternate scaling or
replaced for a different color as included in the optional accessory kit

6
Gauge Assembly
STEP 1 - Place the lightguide (5) on a flatsurface (black side up) and
slide the buttons (6) into the slots
STEP 2 - Stack the diffuser (4), faceplate (3), and lens (1) in order, over
the buttons, and on to the lightguide
STEP 3 - Reassemble the PCB and display stack with the bezel, making
sure screw holes are aligned through the entire assembly
STEP 4 - Reassemble and tighten screws to 2 in-lb (previously
assembled bezel) or 3 in-lb (new bezel). Do not over-tighten!

Gauge Installation
Installation using supplied bracket
Installation without bracket, using rubber band
A 2-1/6" (52mm) hole is required to mount the X-Series gauge. A bracket and thumbscrews are provided to facilitate
installation into a panel or gauge pod. In some cases, the gauge cup may be pushed into a mounting hole causing an
interference fit strong enough to retain the gauge; the supplied rubber band may be fit to the gauge to create a tighter fit in
mounting holes slightly larger than 52mm. It is, however, recommended that gauges be mounted securely using the
supplied bracket to ensure they never become loose and cause a hazard during vehicle operation.
Note: The gauge is not water-proof and should not be installed in a location with exposure to water or snow. Damage
caused by water ingress will not be covered under warranty.

FAQ / Troubleshooting
I installed my gauge correctly and the display just shows "CAn"
The gauge is not detecting the expected AEMnet/CAN traffic. Please check that you have other AEMnet enabled devices
connected to the bus, properly terminated, and powered on. For custom installations, refer to the Bosch CAN 2.0b
specification for proper wiring and termination techniques.
What pins are used in the connector?
To populate optional extras, use JST P/N SPUD-001T-P0.5 terminals for 22-26 AWG wire.
