GlowShift Digital Series Wideband Air_Fuel Ratio Gauge - Manual (Page 2)

Calibration Schedule
Prior to calibration remove the sensor from the
bung. This will ensure a proper calibration.
To obtain the most accurate results from your gauge,
please follow the calibration schedule pre and post
installation:
A. For Everyday Driven Vehicles

Calibrate after installation.

Calibrate again, after 3 months of use.

Calibrate twice a year or every 10,000 miles
(whichever comes first).
B. For Race Vehicles

Calibrate after installation.

Calibrate once per race weekend.
C. Dynamometer Use

Calibrate after installation.

Calibrate every 2-3 days, depending on the
amount of usage.
Functions:
1. Prior to operation, the sensor must warm up for 30 seconds. This is a
mandatory process every time the gauge and sensor are powered from a cold
vehicle start. The LED display will show a scrolling graphic until the warm
up phase is complete.
2. If necessary you may perform a manual calibration by pressing the button on
the controller for 3 seconds, to initialize a controller /sensor calibration
sequence. The LED display on the gauge will show a [2] until the calibrating
process is over.
3. If the LED display on the gauge shows a [3] then there is a sensor error
detected. Check and confirm the connection of the sensor and wire harness
to and from the controller unit. If the connections are secure and in place,
press the button on the controller for 8 seconds to reset the controller to the
original factory settings. The LED display will show a [2] and then a [4].
After this the factory settings are programmed and restored to your controller. If
your display shows a [3] again, your sensor may be defective.
Data Logging Output: Offers two analog outputs for monitoring and capturing Air / Fuel Ratio using a third party data log device
Wire Color Function Connection Signal Voltage
Green Provides the positive (+) analog NARROWBAND voltage output signals. Data Logger (+) 0– 1 volts
Brown Provides the positive (+) analog WIDEBAND voltage output signals. Data Logger (+) 0 – 5 volts
Black Provides the negative (-) ground reference for both analog NARROWBAND &
WIDEBAND voltage output signals. Data Logger (-) Ground
Digital Display: This gauge is equipped with a Digital A/F Ratio display with a range between 10 ~ 20 AFR. If the AFR is below 10 or
higher than 20 for more than 3 seconds the display will flash.
AFR Quality AFR Value
RICH: 10 ~ 12.9 AFR
OPTIMAL: 13 ~ 17.9 AFR
LEAN: 18 ~ 20 AFR
Additional Installation Information & Material Requirements

GlowShift Gauges Approved Conductor Wires: Successfully installing GlowShift Gauges may require lengths of wire (sizes and quantity
depend on vehicle, gauge type, gauge location and / or sensor location). For correct and proper GlowShift Gauge installation and operation, the
use of 18 Gauge (wire diameter) automotive grade conductor wire with sheathing is recommended for one or more gauges per vehicle. When
installing and routing wires from the engine compartment, to inside the vehicle cabin, always employ the use of a rubber grommet. This will
prevent and deter the stripping of power supply and / or sensor wires that is necessary to deliver vital statistics about your engine to your
GlowShift engine monitoring instruments. Never use wire nuts to fasten or bound vehicle / gauge or sensor wiring. Always use securing crimp
connectors or solder individual wire junctions together for optimum gauge installation and operation.

GlowShift Gauges Approved Installation Accessories: GlowShift Gauges may require the installer or user to provide additional products,
accessories or adapters for the correct installation and operation of a gauge or sensor, as per the GlowShift Installation Instructions. When
installing and routing hoses to or from the engine compartment, to inside the vehicle cabin, always employ the use of a rubber grommet. This
will prevent and deter the stretching or pinching of hoses that is necessary to deliver vital statistics about your engine to your GlowShift engine
monitoring instruments.

GlowShift Gauges Installation Instructions: Installation documents are solely to provide a guide for individuals that are mechanically and
electronically able to install products. If you are unsure about the correct procedure of installation for a product or device, you should consult a
professional mechanic or an Authorized GlowShift Installer.
