Fantastic Wideband Gauge for Automotive Enthusiasts

This gauge is an excellent addition to any car enthusiast's kit. It offers an accurate, easy-to-read display of air/fuel ratios necessary for tuning and perfecting performance. The blue glow it emits creates a futuristic, high-tech aesthetic. However, the gauge can be difficult to install and potentially cause damage if not installed correctly.

Pros
  • Accurately measures air/fuel ratio and displays it in real time on a clear digital screen
Cons
  • Expensive compared to other wideband gauges on the market

Don't waste your money on this sensor

Don't waste your money on this sensor. I bought it through Revain and had it professionally installed when I set up my machine. The sensor worked for a day and then stopped. It only ever shows the default value of 14.7 AF. My installer called Autometer and fixed the sensor problem. They keep saying it's a ground even though he grounded it exactly as they instructed and it still doesn't work. Find out more online before you buy. A ton of others are having the same issues with this sensor…

Pros
  • Absolute legend
Cons
  • Mostly good, but...

Digital display failure after 5 years

Purchased direct from Summit Racing so you will not see a verified purchase tag in this review. But you need to know no matter what. Installed in 2016. That summer, the digital display's LED segments began to fail. Now it becomes difficult to interpret the numbers as most of the numbers are missing at least two segments, so it could be "1" or "4" etc. This has nothing to do with the reliability of the sensor, but it would certainly be nice to have a feature that turns it off or dims it heavily…

Pros
  • Weight
Cons
  • Quality
