Wiring Diagram
Warnings on Wiring
· As a general rule, never route the harness close to ignition wires.
· Route the harness very carefully to avoid chafing or undue strain.
· Secure wiring to the vehicle with wire ties with particular attention to the sensor
harness routing beneath the vehicle and in the engine compartment.
· Take care when routing sensor harness near hot exhaust components.
· Use a 5A inline fuse on the switched 12V power supply line (RED - Power/IO).
· Avoid cutting or extending the sensor harness.
· Use appropriate gauge wire (20 AWG or thicker) when extending wires,
especially RED (Switched 12V with min 3A) or BLACK (Ground) of the
Power/IO harness.
· Ensure all connections are secure and insulated from shorts to adjacent wires
and the vehicle structure. Utilize proper crimping and solder/heat shrink
techniques.

Connectors
WB WIDEBAND D2 comes with a harness that is connected to the gauge, as
shown below. Wideband connector goes and clicks to Bosch (#17014) LSU4.2 O2
sensor connector. The other branch of the harness has the power/IO features. At
a minimum, switched 12V RED (5A fuse) and ground BLACK wires need to be
connected, as explained above.
Calibration
Please note that all WB WIDEBAND products are tested and calibrated just before
they are shipped from Cincinnati, OH, validating that they are working properly. No
need for any calibration when first use. However, if there is any change in setups and
environment being used (altitude, temperature, etc.), it should be open air calibrated.

The O2 sensor should be exposed to free air for the first time calibration if needed.
Hold the button back of D2, and you will see display unit counting from 1 to 6.
Hold the button until you see 6 and release it to complete the calibration. This should
take less than 60 seconds.
Once it calibrated, the display reads 19.0 at gasoline settings. You can now connect the
O2 sensor onto the exhaust pipe.
For the factory settings, disconnect power, hold the switch while turning the power
on and wait for 3 blinks. You should re-calibrate after this action.
Faceplate / Bezel Assembly and Disassembly
The default gauge comes with a black faceplate and black bezel. There is a white
faceplate available as an accessory or an option. When you want to use D2 with
different fuel types or lambda scales, you can replace the faceplate accordingly to
lambda, diesel, E85, etc.
Disassemble is so easy since there are only four parts involves, as seen in the picture
below. They are a bezel, faceplate, PCB electronic board, and a case. No screws, no
buttons, or brackets are involved.
Just pop the bezel out first. Either push the faceplate out from the connector at the
back or pull it out from the front side via tweezers or small screwdriver. Take the PCB
board out when you need to replace it with a new one.

Bung and Plug Replacement
The stainless steel (SS304) bung and its mild steel plug can be purchased either
from www.wide-band.com or another retailer available. The specs are M18 X
1.5mm.
O2 Sensor Installation on an Exhaust Pipe
The bung should be installed (welded) from the side so that the sensor orientation is
greater than 10 degrees but not greater than 45 degrees from the horizontal line. That
helps for perfect condensation drainage from the sensor. Otherwise, the sensor may
prematurely die.
Wideband O2 Sensors
Handle with caution! They become hot quickly. They can burn human skin and can
start a fire.
In the end, they are sensors, and they are very sensitive to harsh usage. So please handle
with care. NO WARRANTY is offered for the sensor because it is impossible to verify
the user’s operating conditions for the sensor.
Sensor life gets shorter with the followings:
Leaded fuel
Silicone
Oil
Coolants
Excessive rich AFR
2 stroke engines
Damaging by dropping to the ground or hitting hard to other surfaces
Thermal shock
Extreme exhaust temperatures (above 930 Celsius or 1700 F)
Unheated (no powered) sensor left in exhaust pipe stream
Gauge Installation on a Pod
The WB WIDEBAND gauges are universal 52mm (2-1/16”) diameter in size.
They can be “pushed-in” to a universal 52mm pod. If the fitment is not solid, a
black tape can be applied on the perimeter of the gauge and re-insert it back to
pod for a nice and snug fit.

Analog Output (White Wire)
0-5V analog output scaling formula for Gasoline AFR = (2 * Volts) + 9. It is
Lambda = (0.136 * Volts) + 0.61.
Please refer to drawing on page 2 for analog output connections for ECU data
logging. There are 256 steps involved, which means 0.04 AFR per step between
0V and 5V. The picture below shows the setup screen for MegaSquirt.

Digital Output (Green Wire)
The digital output is for monitoring the readings from a PC or from WB G1 LED
display. Please refer to drawing on page 2 for digital output connections via DB-9
connector to a PC. Baud rate is 9600 bps, data bits is 8, no parity, and stop bits is
1 (9600 8N1).
1- Wire the DB-9 pin numbers 2 and 3.
2- Run http://www.ontrak.net/adrcom.zip application.
3- Select and open the related port.
4- Write some letters on the black area on the software.
5- If you see a repeat of the letters, then all is correct. (When you type “A”, it
should display another “A” next to it immediately.)
If not, check to comport numbers. Go to device manager and change the port
number to something lower than 9.
We use a single-byte protocol. It is not ASCII. If it reads 1 then the device is not
ready. Otherwise, it should read 90 to 190.
90 = 9.0 AFR
190 = 19.0 AFR
147 = 14.7 AFR
This will be only for gasoline, even if you change the fuel type to others.

FAQ & Troubleshooting
What is the minimum wiring needed to start using the gauge?
The RED and BLACK should be connected. The rest of the wires can be secured
away. But first always perform the bench test as described on the website:
http://www.wide-band.com/help_answer.asp?ID=17#253
DO I need to calibrate right after out of the box?
No.
The display shows 8.88 when connected or at full throttle.
There may be several reasons. Please check the voltage level and verify if it is min
12V and 3A. Use a scope to monitor if there are any voltage spikes in the system.
You can apply a min 35V capacitor to smooth out the spikes.
http://www.wide-band.com/help_answer.asp?ID=17#254
My gauge got stuck at A1, A2, 9, or 19AFR.
Check your sensor location and the sensor itself if there are any contaminations
built upon it. Perform a factory reset if the problem persists. For the factory
settings, disconnect power, hold the switch while turning the power on and wait
for 3 blinks. You should re-calibrate after this action. If you still having the issue,
please take a clear and close picture of the PCB board for remote inspection by
following the directions above to disassemble the gauge. Please email that and the
order details to support@wide-band.com.
Follow the directions as described on the link, if you need to send the product
back to us for inspection or repair: http://www.wide-band.com/returns.asp
Can I extend the wires in my sensor harness?
Yes. Please follow the guidelines listed on page 2.
Can I install D2 on my motorcycle?
If you are going to install the D2 to a motorcycle permanently, you can follow the
guidelines below.
The temperature of the location. <700C
6 inches, away from the end pipe
Ability to install 10 degrees above horizontal in the desired location
We are mainly experienced in cars and know that motorcycles are a pain in the ass in
terms of voltage spikes. But as a general rule, nobody should wire anything close to
ignition wires even in cars.
check voltage spikes by using a scope not voltmeter
isolate the O2 sensor area from the voltage spikes

check your ground and be sure that you get the max grounding possible
if needed use a metal sleeve on the gauge wire and ground it
keep trying other solutions.
The Internet has tons of discussions about this. Such as

&page=3
Any plans for introducing LSU4.9 sensor with the D2?
We still believe LSU4.2 market is much bigger. Plus, it is more reliable when you
perform open-air calibration rather than relying on self-calibration. We do not plan to
utilize LSU4.9 sensor soon.
