What is a wideband gauge?
The Best Wideband Gauges (Review) in 2019. Wideband gauges are designed to measure the air-fuel ratio in a vehicle’s internal combustion engine. They’re a special kind of air/fuel ratio gauge (also known by the acronym AFR gauge), developed for greater accuracy than the previously used ‘narrow gauge’ models.
Can a wideband O2 sensor be used as a tuning tool?
The opposite would be true if the sensor was telling the ECU that it was currently running lean, it would richen the fuel map till the o2 sensor was reading stoic. A wideband o2 sensoris much more sophisticated than a narrowband sensor, and can be relied upon to be used as a tuning tool.
What is a wideband air/fuel ratio gauge?
Published Apr. 29, 2019 Wideband gauges are designed to measure the air-fuel ratio in a vehicle’s internal combustion engine. They’re a special kind of air/fuel ratio gauge (also known by the acronym AFR gauge), developed for greater accuracy than the previously used ‘narrow gauge’ models.
What is wideband sensors?
Wideband sensors give the ECU the ability to tune exact A/F value’s to a tenth of a decimal instead of just richening and leaning the mixture till a stoic value is seen. What is Stoic, Rich, and Lean?
Do I need wideband to tune?
You could never tune WOT without a wideband and have any hopes of guessing your fueling 100% correct. You may be commanding 11.96 AFR but there is a good chance that that is not the true real time AFR that engine is seeing. The wideband is a must to dial in fueling.
What does a wideband do?
A wideband oxygen sensor (commonly referred to as a wideband O2 sensor) is a sensor that measures the ratio of oxygen to fuel vapor in the exhaust exiting an engine. The measured ratio is expressed as parts of oxygen to fuel.
What is the benefit of using a wideband 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.
How do I know if I have wideband or narrowband?
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).

Do I need a wideband o2 sensor for tuning?
You need solid data to tune your engine right. A wideband o2 sensor gives you the data you and your ECU need to be able to tune that properly. While a narrowband can only tell you when it's 14.7:1, and is therefore nearly useless for tuning for anything other than a steady cruise condition.
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.
What is the difference between wideband and narrowband?
Narrowband systems typically have lower data rate transmissions, whereas wideband systems support relatively higher data rate transmissions. To put simply, wideband systems allow for faster communication.
How do you tune a carb with a wideband?

Changing the Jets is the biggest effect on overall performance.
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.
What is considered wideband?
In communications, wideband is defined as a higher rate of transmission in contrast to a lower "narrowband" rate. The metrics are different depending on the type of communications, and the lower and upper limits change as time and technology advance forward.
Can I replace my 02 sensor with a wideband?

What is wideband receiver?
Wideband receivers typically down-convert from frequencies like 900 MHz to basebands of from 5 to 25 MHz, using a fixed local oscillator—and convert directly to digital. The many individual signal channels within are filtered, demodulated, and processed digitally.
Why is it called wideband?
Wideband sensors were developed to more accurately measure A/F ratios over a broader range of operating conditions (hence the name).
What is a wideband gauge?
A Wideband allows you to read the exhaust gasses post-combustion. Once you know how much oxygen is remaining in the exhaust, from that you can deduce the A/F of the engine. HOWEVER, the gauge can (WILL) read wrong if you have exhaust leaks before the O2 sensor.
What does "lean" mean on a wideband?
The last very common problem is an ignition problem (ignition miss), which will also show on the wideband as “lean”, as all that O2 goes into the exhaust system. It is critical that you understand that the wideband reads OXYGEN, not fuel! An engine will run pretty easily, even in poor tune.
Can an engine run in poor tune?
An engine will run pretty easily, even in poor tune. Low compression, lean or rich mixture, retarded or overly advanced spark, etc. To get “good combustion”, all need to be within a tight range of operation. This creates a smooth and efficient engine, which doesn’t hesitate, and doesn’t create too much heat.
Why use wideband gauge?
Using a wideband gauge to keep track of your engine’s air/fuel ratio comes with a range of benefits, including: Wideband gauges are ideal for diagnostic purposes. Wideband gauges are ideal for engine calibration purposes. Using a wideband gauge allows for more accurate.
Why install wideband gauges in cars?
Installing a wideband gauge in your car brings a range of benefits – they help you keep an eye on the oxygen sensors, improve fuel economy, and reduce emissions. Overall, these highly accurate sensors are a boon to anyone who wants to tune a vehicle.
What is an innovate wideband gauge?
Featuring patented DirectDigital technology, the handy device can display a vehicle’s air to fuel ratio with precision and speed. The gauge can also calibrate your car’s O2 sensor, for maximum accuracy.
What is the output voltage of a wideband gauge?
Many can be connected to existing ECUs, EMS, and data loggers, thanks to an extra output port. Outputs from a wideband gauge usually range from 0-4 volts.
VE tuning with HPT Wideband and Narrowband how to
Guys feel free to read and discuss. I will make changes as we see necessary through our discussions.
Re: VE tuning with HPT Wideband and Narrowband how
Ok the reasoning for the 13.0 is because it is a safe afr to opperate at all RPMs with. With that being said yes you will be logging points as high up as you can rev. The thing to keep in mind is that the 13.0 is only temporary, when you get to step 10 and above (changing the tables back to stock) the computer will be commanding stoich.
Re: VE tuning with HPT Wideband and Narrowband how
As far as the timing goes...it really depends on if you are going to stay mafless or not. If you do intend on staying mafless then, no you will not change it back. When in mafless/sd mode the computer falls back on the low octane table as it primary refernce for spark.
Re: VE tuning with HPT Wideband and Narrowband how
Yes you will not pass the readiness test with the MAF unplugged. I am trying to figure out a work around for it. I let you guys know when I do.
Re: VE tuning with HPT Wideband and Narrowband how
Another new person with this software... I have been learning a lot in the last few days. Thanks for the info. A couple questions I do have is when you are logging the info in the histogram chart, do you use average or last value (when tuning the VE using ltft and stft values)? I would assume average, but assumptions can be bad...
Re: VE tuning with HPT Wideband and Narrowband how
I have never seen a definitive answer on this.... can this sort of tuning be done on an a4 car with the maf unplugged?
Re: VE tuning with HPT Wideband and Narrowband how
Cool, thanks!!! I still see values in my LTFT Histogram tab, is that ok???
