What Is a Wideband Air-Fuel Gauge?

You can choose between narrowband or wideband options when installing an air-fuel controller on your vehicle. Narrowband gauges are simplistic and only tell you if your vehicle is running rich or lean, not how rich, or how lean. They are not useful in high-performance vehicles. If your car has a turbocharger or has a high performance of high compression naturally aspirated engine, you want to invest in a wideband since it gives you more specific AFR information, allowing you to tune your vehicle more accurately.

Why Wideband Turning Is Important

When wondering how wideband tuning can improve your vehicle performance, it's a matter of having the information you need to best tune your engine. Without a proper air-fuel gauge, you may run your engine too rich (too much fuel, which can lead to poor performance) or too lean (too little fuel, which can lead to engine damage) without realizing it. Using a wideband allows you to get accurate data on the efficiency of the combustion process in your engine, giving you the information you need to tune for optimum performance and fuel efficiency.

Best Wideband Gauges for Tuning
