Best Wideband Gauge Buying Guide

These wideband gauges are among the best on the market right now, and we’re confident you’ll find the perfect option for your needs somewhere on the list. To help you work out which option is right for you, and get the most out of your new gauge, we’ve put together this handy guide. Below we run through some important information about wideband gauges, how to select one, and how to get the most out of it.

What is a Wideband Air/Fuel Gauge?

Since the internal combustion engine’s earliest days, over a century ago, tuning has been an important practice for maximising power output and efficiency. In previous years, tuners would use vacuum gauges, CO meters, and even attempt to ‘read’ spark plugs. However, these methods were often inaccurate, and tuning was considered to be more of an art than a science.

Wideband gauges were developed to address this important issue. These gauges measure the ratio of fuel to oxygen exiting an engine’s exhaust, using highly accurate ‘wideband’ oxygen sensors. This data is fed into a computer system via electronic signals, which is interpreted into a clear numerical figure that appears on the gauge display. At the same time, data can be channeled from these wideband sensors to the ECU, which subsequently determines the optimal fuel/air mixture for good efficiency and lowered emissions.

Things to Consider When Buying Wideband Gauges

If you decide to install a wideband gauge in your vehicle, there are few factors to bear in mind:


It’s important to ensure that a wideband sensor is compatible with your vehicle and other equipment. 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.


Wideband gauge displays are quite diverse in appearance, giving you the option to choose a display that’s easy to see. Look out for adjustable brightness, anti-glare protection, and a ‘needle’ style display that’s easy to read at a glance.

Accuracy & Responsiveness

Wideband gauges are at their most useful when they can measure and convey the air/fuel ratio quickly and accurately. Although it’s difficult to tell how well a gauge will work prior to installation, it’s a good idea to watch out for Bosch sensors, as these are typically a high quality component. Checking for feedback from other customers can also provide plenty of insight into the device’s performance.

Extra Features

Some wideband gauges come as part of a set, such as number nine on our list. This AFR gauge is accompanied by a boost gauge, making it an excellent option for vehicles fitted with turbo chargers. Other features to look out for include interchangeable faceplates and bevels, automatic air sensor calibration, and the inclusion of tuning software.

Benefits of Using a Wideband Air/Fuel Controller

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
  • Wideband gauges can display live data about the AFR to your dashboard
  • Certain wideband gauges can be set up to automatically adjust AFR for optimum performance
  • The majority of wideband gauges are quick and simple to install in many vehicles

How to Calibrate Your AFR Gauge

The exact calibration process will vary between devices, but usually consists of the following steps:

  • Disconnect the O2 sensor cable, and unbolt the sensor from the O2 bung
  • Power the vehicle’s electronics by turning the key to the ‘on’ position
  • Wait at least 30 seconds
  • Turn the key to the ‘off’ position, before reattaching the sensor to its cable
  • Power up the electrical system with the sensor in free air (ie. not in the exhaust)
  • Wait for the display to read ‘CAL’
  • Power the electrical system down once again, before reconnecting the sensor to the exhaust system

For naturally aspirated cars, recalibrating around once a year should be sufficient. For forced induction vehicles, this should be increased to twice each year, while race cars running on leaded fuel should recalibrate these sensors every week.

How to Get the Maximum from Wideband Sensors

Wideband sensors are a complicated piece of equipment, but even naive tuners can get the most out of them with these tips:

  • Be sure to calibrate oxygen sensors on a regular basis, to maintain greater accuracy
  • Place the sensor at least 24 inches downstream from the cylinder head exhaust ports
  • Recalibrate the sensors if your vehicle experiences altitude changes of 5,000 feet or more – different air pressure means different oxygen concentrations



What should a wideband gauge read?

A: A wideband gauge is designed to measure your engine’s air-to-fuel ratio, so these details are the two details any good gauge should measure. More advanced models, or two-in-one gauges, may measure more, but the air-to-fuel ratio is a minimum requirement.


What’s the ideal wideband gauge reading?

A: Ideally, you want your engine to return an air-to-fuel reading of 14.7 to 1 (or 14.7:1). That ratio should appear when you’re at an idle and while you’re cruising.


What’s the difference between a narrowband gauge and a wideband gauge?

A: While narrowband gauges have sensors that can measure anywhere from 14.0 to 15.0 air levels and report a rich or lean situation, a wideband gauge offers more. With a wideband gauge, you’ll be able to use the sensors to detect more, including oxygen in your exhaust and numbers that are way below or way above the ideal 14.7:1 ratio. It gives you a wider range so you can see exactly where problems are happening (and how extensive they are).

Our Top Pick

For us, the best air fuel ratio gauge on the market right now has to be this versatile and affordable option by AEM. Thanks to its Bosch UEGO sensor, the device can display live data with excellent precision and accuracy. It’s simple to install, too, with 52mm housing that fits into most gauge pods. For a hassle free installation process, the kit includes a weld-in bung, helping drivers to get their new gauge up and running in no time.

What wideband to use with HP tuners? ›

The 30-0334 X-Series OBDII Wideband Gauge is validated to work with HP Tuners VCM Suite! The X-Series Wideband AFR OBDII Gauge includes an OBDII pass-through connector and Bosch 4.9LSU sensor that can be free-air calibrated or used with the factory resistor calibration.

What wideband sensor does AEM use? ›

We 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 should my wideband read at idle? ›

-At idle or a steady cruise, it is normal for your gauge to display an AFR value of 14.0:1-15.5:1 or 0.95-1.05 in lambda. -A naturally aspirated motor under high load will target an AFR value of 12.5:1-13.3:1 or 0.85-0.91 in lambda.

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.

Do I need a wideband on both banks? ›

It doesn't matter. Think about it, you only have 1 map for both banks. You do have 02s for each bank that adjust both sides, but that is a multiplier based off of one table. Dual widebands would only really matter if you were emulating the narrowbands and keeping them there permanently.

Do you have to calibrate wideband? ›

Just like micrometers and dial bore gauges need to be calibrated on a regular basis, wideband O2 sensors must follow a consistent calibration regimen to ensure maximum precision.

What O2 sensor does AEM use? ›

AEM's wideband UEGO air/fuel ratio sensor kit includes a Bosch 4.2 LSU Wideband UEGO sensor, connector plug, pins and plugs, and mild steel O2 bung.

What is a good AFR reading? ›

Best performance for most vehicles is in the 12.5 to 13 AFR range. Going too rich will have the opposite affect and decrease your performance.

What technology is AEM built? ›

Built on Adobe Cloud technology, AEM helps you easily access and use assets from anywhere to support your digital experience without the complexity of networking protocols. Adobe Experience Manager changes the way you operate online.

What is the best AFR at idle? ›

The 14.7:1 ratio is perfect for idling and light throttle cruising conditions as it's the most efficient mixture possible, meaning the best fuel economy and lowest emissions.

What is the best AFR ratio? ›

We mentioned the stoichiometric air-fuel ratio (14.7:1) that is the ideal ratio for lowest emissions, but this isn't the best ratio for power. It used to be that 12.5:1 was considered the best power ratio, but with improved combustion chambers and hotter ignition systems, the ideal now is around 12.8:1 to 13.2:1.

What is the perfect Lambda reading? ›

Checking your lambda sensor with a multimeter

When you start your engine, a reading between 0.4–0.6V should appear. Once the engine is up to temperature, the reading should alternate between 0.1–0.9V. The ideal engine speed for the best measurements should be at 2,500rpm.

How long do wideband sensors last? ›

On production vehicles it is common for these sensors to last for over well over 100,000kms.

What is better wideband or 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.

Can you tune a car without a wideband? ›

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.

How many wires does a wideband have? ›

A wideband sensor looks similar to a Narrowband but typically has 6 wires and a bulkier mating connector to the engine harness. It also needs rather complicated electronics to control the magic inside the sensor (while the narrowband signal can be read by a simple ECU input).

How do you test a wideband sensor? ›

On aftermarket scan tools that lack this test function, you can use the following procedure to test the A/F sensors: Idle the engine for 30 seconds, then raise the engine speed to 2,500 rpm and hold steady. Watch the voltage reading for the sensor.

Does wideband connect to ECU? ›

The wideband is connected to the pin on the ECU that the stock narrowband O2 sensor connects to. You can simply cut the stock wire close to the ECU plug and solder the Wideband O2 analog 0-5v wire to the wire coming from the ECU. Or alternatively you can utilize the stock O2 sensor harness.

How do you test a wideband O2 sensor with a multimeter? ›

Set the multimeter to the 1-volt range, back probe the O2 sensor's signal wire with a pin, and warm up your car for about five minutes. Connect your positive multimeter probe to the back probe pin, ground your black probe to any metal surface nearby, and check the multimeter for reading between 100mV to 1000mV.

Is it OK to use aftermarket O2 sensors? ›

We always recommend buying OEM parts instead of aftermarket parts. They are a safer bet. But, we strongly recommend it to anyone looking for a replacement oxygen sensor. These sensors serve an important role in ensuring the smooth operation of your engine.

Which O2 sensor is closest to the engine? ›

Sensor 1 is the sensor closest to the engine. Sensor 2 is the downstream oxygen sensor. It is always going to be located after the catalytic converter. Its job is to monitor the oxygen content exiting the catalytic converter in order to determine if it is operating efficiently.

Are all O2 sensors the same quality? ›

Each oxygen sensor has its own unique characteristics specific to its application. One generic oxygen sensor that may appear to be the same cannot be used to replace a range of these specific oxygen sensors.

Is 14 AFR too lean? ›

In a real engine, a 14.7:1 air-fuel ratio is a little too lean. To compensate for incomplete combustion, and to reduce NOx emissions, modern automobiles are tuned to run more rich, sometimes dipping as low as 12:1 or even richer during high-load situations.

Is 14.7 AFR rich or lean? ›

So what is meant by a rich or lean AFR? A lower AFR number contains less air than the 14.7:1 stoichiometric AFR, therefore it is a richer mixture. Conversely, a higher AFR number contains more air and therefore it is a leaner mixture.

Is 16 AFR rich or lean? ›

For optimum fuel economy 16-17:1 is usually best, leaner than that and the car will begin to misfire. Maximum power is usually found between 12-14:1, but this may be too lean for safety on many engines. For maximum reliability at full power, air fuel ratios from 10.5-12.5:1 are considered best, depending on the engine.

Why is AEM the best? ›

AEM Modules and Functionalities. AEM comes loaded with five modules—Sites, Assets, Mobile, Forms, and Community—which together make it a top-notch CMS platform to create and deliver high-traffic websites, forms, and mobile applications.

Does Amazon use AEM? ›

This Partner Solution deploys an Adobe Experience Manager (AEM) OpenCloud architecture on the Amazon Web Services (AWS) Cloud with high-availability features, which includes Amazon Elastic Compute Cloud (Amazon EC2) Auto Scaling, Elastic Load Balancing, and Amazon CloudFront.

What AFR makes the most power? ›

A naturally aspirated engine, running on pump gasoline will normally make the most horsepower at an AFR of about 12.8 – 13.0. An AFR of about 14.6 will produce the best fuel economy.

What AFR is best for torque? ›

​In the absence of other limiting factors, maximum engine torque occurs at about 13.5 AFR. Under wide open throttle (WOT) conditions, a richer mixture (12.5 to 12.8 AFR) is generally required to reduce cylinder head temperatures and avoid detonation.

Is lean or rich better for power? ›

A rich mixture is more common and not necessarily detrimental to your engine. In the case of a slightly rich mixture, you may notice reduced engine efficiency and worse fuel economy, but the rich mixture will generate more power and actually burn cooler.

What is the perfect ratio of air fuel mixture? ›

The theoretical air–fuel ratio mixture for a gasoline fueled engine, for complete gasoline fuel combustion, the stoichiometric air–fuel ratio is about 14.7:1. In order to completely burn 1 kg of gasoline fuel, the combustion process needs 14.7 kg of air.

What is the best AFR for E85? ›

What they really detect is the ratio of oxygen to ideal oxygen for a stoichiometric combustion (the 9.8 AFR for E85 or 14.7 AFR for a typical E0 fuel). So if your AFR is set for Gasoline, it should read close to 14.7 AFR even if you are using E85 that is really 9.8.

What is the AFR for E85? ›

8, the AFR of gasoline will be 11.76 and E85 will be 7.8. That's cool, but what else does it do? There are many other benefits to running E85 besides its energy output. For starters, it has an octane rating of 105 or higher and is incredibly resistant to engine detonation.

What does it mean if lambda is greater than 1? ›

What should lambda be at idle? ›

Unless you're shooting for emissions go as rich as needed to have reliable, solid idle. For light throttle cruising, you should be around 1.1 or even as lean as 1.2 with some engines - that'll give the best fuel economy and also minimise oil dilution, plug fouling, and other potential problems.

Can I upgrade my MPVI2 to pro? ›

Any existing MPVI2+ standard can be upgraded to a Pro Interface with a simple firmware upgrade and Pro Link (included with purchase).

How many credits do you need to unlock HP Tuners? ›
