What is a Wideband Oxygen Sensor?
- Accuracy is top priority. If the wideband's readings are inaccurate, you may make fuel adjustments in error resulting in a loss of power or even worse, engine damage.
- Speed. The wideband must be responsive to changes in air/fuel ratio to allow accurate fuel adjustments for changes in engine rpm and load.
- Ease of installation/ Compatibility. ...

How does a wideband O2 sensor work?
The wideband air/fuel ratio sensor combines an oxygen-sensing “Nernst” cell from the narrow band sensor with an “oxygen pump” to create a device that gives a wide range response to various air/fuel ratios. The Nernst cell senses exhaust gas oxygen in the same as a conventional narrow band O 2 sensor.
What is the difference between a wideband and narrowband O2 sensor?
Wideband sensors were developed to more accurately measure A/F ratios over a broader range of operating conditions (hence the name). A narrowband sensor can measure only between approximately 14.0/15.0:1 air/fuel ratios to report a rich or lean condition, but a wideband is much more robust.

How do I know if my O2 sensor is wideband?
FInd the first one on the list and click on it to go to detail page. Scroll down past the "Features and Benefits" section, and look for "OXYGEN SENSOR TYPE" It will tell you if it is Narrow-Band or Wide Band (heated or un heated doesn't matter to us).
What is the benefit of using a wide band sensor?
Wideband sensors also open up the entire fuel table to the closed loop. This gives you absolute accuracy of air/fuel ratio at all times, even when you're pushing your engine to its limits. This is why nearly all tuning professionals use strictly wideband sensors.
Do I need a wideband?
If you plan to head to the rollers to get it setup, and want a more hands-off install, then no need for a wideband at all. The dyno operator will use their own wideband during mapping, will optimise the fuelling and ignition, and, everything being equal, it should never change once tuned.
Why do I need a wideband O2?
Wideband O2 sensors monitor the amount of oxygen in the exhaust to measure the Air Fuel Ratio, or AFR. The AFR tells your tuner whether the car requires more or less fuel to achieve the best power or economy, and allows your tuner to keep the engine safe.
Is narrowband or wideband better?
A common definition (ETSI) of narrowband is when 25 kHz or less is used for the radio channel. The benefit of using a narrow channel is the lower noise bandwidth and hence better sensitivity and range. The advantage of wideband is the capability to transfer higher data rates.
Where do you put the wideband O2 sensor?

So you don't get the moisture from the condensation.
How can you tell the difference between wideband and narrowband?
Narrowband systems typically have lower data rate transmissions, whereas the wideband systems support relatively higher data rate transmissions. Wideband signals are generally greater than 1 MHz in bandwidth. More bandwidth translated into higher data rates, in terms of transmitted and received signal information.
How long do wideband O2 sensors last?
- Wideband O2 sensors only last 10-50 hours on leaded racegas. - If your controller has the capabilty you should remove your sensor from the exhaust and calibrate your setup to free air every 250-500 hours.

What O2 sensor does the AEM wideband use?

What sensor does the AEM wideband use?
Bosch 4.9 LSU sensorsWe use Bosch 4.9 LSU sensors in our wideband controllers. Our sensors are individually laboratory-calibrated by Bosch and never require free air calibration!
What is a wideband O2 sensor?
A Wideband O2 sensor can be used by the Elite ECU for monitoring purposes, or for closed-loop O2 Control. A wideband sensor, by definition, measures a broad section of the AFR scale. As such, a Wideband O2 sensor is a preferred sensor to be used for accurate engine tuning.
What happens if O2 sensor is heated?
If an O2 sensor is heated before starting a cold engine, the water droplets that pass through the exhaust system upon engine startup will cause condensation to collide with the hot sensor. This Thermal Shock can destroy wideband sensors.
What does O2 mean in ESP?
The Wideband O2 channels in ESP will display the Lambda values from the wideband sensors. Under certain conditions, these channels will also display if there is a fault. See below for the Wideband O2 channel state descriptions and datalog values:
Can O2 sensors be connected to Elite ECU?
Note that wideband O2 sensors cannot be connected directly to Elite ECUs (with the exception of the Elite Pro Plug-in Ford Falcon ECU). An external controller unit must be used with wideband O2 sensors. Page Contents. Wiring Tab.
Why is my wideband oxygen sensor only designed to read the oxygen content of the exhaust gases?
Because the stoich AFR mixture changes with the type of fuel being used , many people become confused when their wideband gauge displays the wrong AFR targets for their fuel choice. This is because your wideband oxygen sensor is only designed to read the oxygen content of the exhaust gases and doesn’t care what fuel is being used.
What scale is wideband gauge?
Left: Wideband gauge displaying a stoich AFR in its converted gasoline scaling. Right: Wideband displaying a stoich reading in its native lambda scale. There are some enthusiasts that will over react under certain driving conditions because they don’t know how to interpret what their wideband gauge is telling them.
What is AFR gauge?
Many enthusiasts have a wideband oxygen sensor and air/fuel ratio (AFR) gauge installed at the recommendation of their tuner or friends (if not already factory equipped), but don’t fully understand how to interpret the readings or what the target value should be under various conditions. Reading a wideband gauge is important for power hungry ...
What does a narrowband sensor know?
Narrowband sensors only know three things: lean, rich and stoich. Depending on the oxygen content it reads in the exhaust it sends a signal between 0 and 1 volt. 0 means too lean and 1 means too rich.
What does more oxygen mean on a bike?
More oxygen means it’s running lean and less oxygen means it’s running rich. What fuel tuners do is offset the ECU signals to change the ratio to make more power or to create adjustments based on new bike modifications. Narrowband sensors only know three things: lean, rich and stoich.
What is the optimal air/fuel ratio?
For pump gas, that ratio is traditionally 14.7:1 but it changes depending on the amount of ethanol present and/or the fuel type used. For other fuel type stoich points we have a table at the bottom to help you out.
How many wires are needed for a sensor?
wire by testing. The sensor can have 2, 3 or 4 wires (some can have 5 or 6- these are rare), and you have to know which one is the signal wire. The most common configuration for modern cars is 4 wires. If you have 2 or 3 wires, then you can have a common ground, or no heater wires etc. The simplest.
Do 02 sensors produce a signal?
NOTE: The engine must be at operating temperature to perform this check. Many 02 sensors do not. produce a signal until the sensor is warmed to 600 F. If you can not find a signal wire with fluctuations. between 0-1 volt, there is a possibility that you have Wideband 02 sensors.
