Wiring
Use 20 AWG stranded or heavier wire for installation. Route wires away from
any moving parts and hot engine components. Secure wires firmly along their
route.
Cut and seal all unused wire connections.
Note: As a safety precaution, the RED (Pin 5) and PURPLE (Pin 1) 12V+
connections should be fused. We recommend using a 1 Amp, 3 AG fast-acting
type cartridge fuse.
Signal Input
The gauge is setup to work with the Innovate Motorsports’ factory wideband
output of 0v = 7.35 A/F and 5v = 22.39 A/F.
MENU Button Installation (Optional)
Installation of the remote MENU button is only necessary if you want to use the
RECALL and WARNING features of the gauge. Installation of the MENU
button is NOT required if you do not wish to use the RECALL or WARNING
features.
Mount the included MENU button in a location that is convenient. Connect the
red wire from the button to Connector 2, Pin 1 (Red) and the black wire on the
button to Connector 2, Pin 2 (Black). See Fig 1.
Lens Protective Film
The gauge comes with a soft protective plastic film on the lens. Carefully
remove the protective film when gauge installation is complete.
Lens Cleaning
The gauge lens is made of acrylic plastic. Do not use any chemicals or
abrasives on the lens. To prevent scratching, caution must be used when
cleaning. To clean, wipe lightly with a damp soft cloth.
Programming Full Dial Low Warning (WARN LO)
This gauge can be configured to show a full dial low warning (flashing amber
backlight) when the gauge goes BELOW a specific value (i.e. AFR goes below
10).
1. To access WARN LO programming mode, press and hold the
MENU button until the pointer moves to 25% scale (approx 1
second). Release the MENU button after the pointer has reached
25% scale.
2. After releasing the MENU button the pointer will move to the current
low warning set point. Factory default is 0% scale (WARN LO
deactivated).
3. To change the set point, press the MENU button repeatedly to move
the pointer by 2% increments. Once the pointer reaches 100%
scale, pressing the MENU button will decrease the pointer position
by 2% increments.
4. Once the pointer indicates your desired low warning set point leave
the MENU button untouched for 5 seconds. The low warning set
point will be saved and the gauge will return to normal operating
mode.
To turn the low warning OFF, repeat steps 1-4 above and change the low
warning set point to 0% or 2% scale. Setting the low warning set point to 0%
or 2% deactivates the low warning feature.
Programming Full Dial High Warning (WARN HI)
This gauge can be configured to show a full dial high warning (flashing amber
backlight) when the gauge goes ABOVE a specific value (i.e. AFR goes above
17).
1. To access WARN HI programming mode, press and hold the remote
button until the pointer moves to 75% scale (approx 3 seconds).
Note: the pointer will stop at 25% scale for approx 1 second (for
WARN LO programming mode), continue holding the button until the
pointer has reached 75% scale. Release the button after pointer
has reached 75% scale.
2. After releasing the button the pointer will move to the current high
warning set point. Factory default is 100% scale (WARN HI
deactivated).
3. To change the set point, press the MENU button repeatedly to move
the pointer by 2% increments. Once the pointer reaches 0% scale,
pressing the MENU button will increase the pointer position by 2%
increments.
4. Once the pointer indicates your desired high warning set point leave
the MENU button untouched for 5 seconds. The high warning set
point will be saved and the gauge will return to normal operating
mode.
To turn the high warning OFF, repeat steps 1-4 above and change the high
warning set point to 98% or 100% scale. Setting the high warning set point to
98% or 100% deactivates the high warning feature.
Viewing and Clearing Peak Value (RECALL)
1. To view the peak value, press the MENU button one time.
2. To exit RECALL mode press the MENU button one time.
3. To clear the stored peak value press and hold the MENU button for
3 seconds while in RECALL mode.
External Warning Output (Optional)
When warning mode is active the gauge outputs a 12V+ DC signal (500mA)
on Pin 1 of Connector #1 (See Fig 1). This output is 0V when warning mode
is not active. This output can be used to activate an external warning light or
activate a switch.
Do not install Connector 1 if external warning output is not required.
Full Dial Warning (ON/OFF)
If desired, the full dial warning can be turned OFF so that only the External
Warning Output activates when a high or low warning condition exists. To
turn Full Dial Warning OFF (or ON):
1. Press and hold the MENU button until the pointer moves to 100%
scale (approx 4 seconds). Note: the pointer will stop at 25% scale
for approx 1 second, then 75% for approx. 1 second. Do not release
the MENU button until the pointer has reached 100% scale.
Release the button after the pointer reaches 100% scale.
2. After releasing the button the gauge backlighting will indicate
whether Full Dial Warning is currently ON or OFF. Gauge
backlighting will flash to indicate Full Dial Warning Mode is ON.
Gauge will remain unlit to indicate Full Dial Warning Mode is OFF.
3. Press the remote button to switch between Full Dial Warning ON
(flashing backlight) and OFF (no backlighting).
4. To save your changes, leave the MENU button untouched for 5
seconds. Full Dial Warning Mode (ON or OFF) will be saved and
the gauge will return to normal operating mode.
