7 Best Wideband Gauges to Get:

Best Wideband Gauges – Reviews & Buyer Guide

Here you can review the top Wideband Gauges available in the market!

Do you have a high-performance car standing in your garage? If yes, you can do anything to take the best care of it. Right! We know how much maintenance such vehicles demand. And it’s up to us to cover that level. So, why not look for its engine and do the best we can!

Here comes a wideband gauge. That, unlike any narrow gauge, measures the wide fuel-air ratio. It keeps your combustion engine checked and stable.

How does it Work?

It simply measures the oxygen levels in your engine and tells if it needs tuning or not. If the fuel-air ratio is off (either rich or lean), it is the most accurate indicator that it’s time to tune in your engine!

One thing to remember, a narrow gauge can work well with regular vehicles. But for a performance one, you need a wideband with better accuracy and precision. 

What are some of its Benefits?

There are many benefits, but we have stated a few;

  • It tells you when to tune your engine (as knowing the fuel-air ratio is essential when tuning it).
  • It monitors your oxygen sensors (it takes the help of these sensors to measure the value, so it keeps an eye on it).
  • It improves your fuel intake (helps in making fuel more compatible with your engine).
  • It reduces unwanted emissions.

What are the things a Wideband Gauge should always have?

Following are the basic features of a wideband gauge.

  • It should show precise and highly accurate results.
  • It should have a quick response time (a minor delay can cause many issues).
  • Its results should be easy to read (a clear display).

Now, you know almost everything you need to know before going into the review of each product. But one thing that’s left is the type of wideband gauges. Yes! There are not just narrow and wideband gauges out there. You can find two more branches coming from the AFR (air-fuel ratio) one!

What Should You Consider Before Buying the Best Wideband Gauge?

AFR Rating:

Your wideband gauge tells you the ratio of fuel and air in your combustion engine. And this is what makes it different than regular narrow-type gauges. 

An AFR rating tells how much your sensor can measure the oxygen content. And it gives the air-fuel ratio accurately. 

So, if you have one with a high rating, like 8-20, you are good to go.

Compatibility:

If your wideband is not compatible with your vehicle, then t’s of no use. How can we determine the compatibility? For this, you have to look into two things.

The first one is the type of fuel your car takes. Wideband can be gasoline compatible or petrol. So make sure you are getting the right one.

The next thing is the electrical systems. Every car’s electrical system can carry different volts, some 20 V or some 12 V.

So, before buying, make sure what your wideband can handle.

Accuracy:

The accuracy of your wideband highly matters. It’s is typically the thing we always look for when buying. For this, make sure you are getting an upgraded oxygen sensor. 

The LSU 4.9 is the best option. So, if you want accuracy in your results, get one with this sensor.

Other than that, a laboratory calibrated gauge performs well and shows precise results.

Other Features:

Extra features contribute a lot to the better working of the gauge. 

It can be the appropriate wire harness or a durable weld-in bung. Everything makes the item more suitable for working. 

Even a bright display with color options is a great addition. And the interchangeable faceplates in some wideband gauges add a worth.

So, before buying, go through some of these features as well.

Frequently Asked Questions (FAQ):

What is an ideal reading of an AFR?
Look for a reading of 14.7 to 1 on your wideband gauge display.
Is checking the AFR rating essential?
Yes, before tuning, you must know the rating of AFR of your vehicle.
Do I need to calibrate my wideband gauge before using it?
Yes, if your wideband gauge doesn’t come calibrated, do it before using it.
