If you’re looking for a great wideband air/fuel gauge, you’re probably running a performance vehicle. And if you’re running a performance vehicle you probably care about your cars. And if you care about your cars, you wouldn’t want to make a bad choice on a part that could greatly affect your vehicle’s engine, would you?
Wideband gauges are not an upgrade from narrowband gauges, they just hold a different purpose. Most cars come stock with a narrowband gauge because that’s all they could ever need. However, if you’re running a more powerful, performance engine, chance are that you’ll be running air to fuel ratios that just can’t be recognized or maintained by a narrowband sensor.
Is it important to get the right AFR? Hell yes!
Wideband gauges essentially are a helper-tool in tuning your engine. In the process of an engine tune-up, it’s vital to have accurate and timely air to fuel ratio information because bad ratios could permanently damage your car. Running too rich of an AFR (too much fuel, not enough air) can cause you to lose power to your engine, and running too lean of an AFR (too much oxygen, not enough fuel) can seriously blow your engine.
What matters when looking for a good wideband fuel gage? Well, since the most important thing they do is measure you air to fuel ratio, the most important thing you can look for is good response time. If there are delays in the data they put out, your ECU could end up compensating for the wrong ratio at the wrong time. It’s also important to look for easy-to-read displays, as you will want to be able quickly see what you’re running.
