Wideband UEGO Air/Fuel Ratio Gauge 52mm (2-1/16”) with 4.9 LSU Sensor, Digital AFR Controller Gauge, Wideband O2 Control Sensor kit | 0-5V Analog Output (10-20 AFR Range)

This controller worked great last summer, but is now dead. The screen is blank. I verified power and ground and tried disconnecting and reinstalling it after waiting a few minutes with no change. I see the seller offers a 24 month warranty, but even though I still have the manual, I can't find any contact info. I would definitely raise my rating if the seller sees this and honors the warranty. Update: The seller sent me a message wishing to honor the warranty with a replacement within 1 day of this post.

Been working spot on for over a year no issues. Only think I can say compared to the authentic AEM gauge is that this one responds just a little slower but is still accurate.

Bought this back in July of 2023 for a project, fast forward to November and I finally got around to installing for use and the gauge itself comes on for 10 seconds or so at a time every minute or so. The sensor is completely dead. Verified this by swapping out my known good Bosch UEGO sensor from the other bank and viewing my data logger it does not read any change in output from this sensor but reads my Bosch sensor output no problem. I’m well past my return date and got what I paid for, absolute unreliable trash. Thought maybe I could save a few bucks but I should’ve just bit the bullet and bought another Bosch sensor like I’m going to have to now

I read as many good things as bad things about this Air/Fuel gauge. I even bought extra Bosh sensors (still in the box today) expecting quick failure of the UEGO supplied sensor. However, all functions and devices shipped with and built into this gauge "kit" are working flawlessly for the past week. This is not a long time track record, but my fingers are crossed for continued performance. In the past, I was not able to get a good tune-up on my Edelbrock model 1406 carb, but with this gauge I can see in real time the results of new jets and metering rods. BAM! Spot-ON! Zippity-Do-Dah! Noticeable improvement in acceleration, emissions and probably economy. I'm still working on lowering the richness from the secondaries under wide-open-throttle (W.O.T.) only because I don't yet have the smaller jets, but this gauge will tell me when I've got it right! My ideal gauge numbers are 14.7 while cruising and 12-13 W.O.T. NOTE: I am using the factory default measurement setting and have not yet used the other 2 measurement settings including (LAMBDA).

Edit 10/24 - Seller reached out and sent me a new one right away, didn't ask hardly any questions. Very cool. Unfortunately the one they sent was damaged. I contacted them again and they very quickly sent me a 3rd set! I am hoping to have the new AFR gauge working again this weekend when I have the time and I'm going to replace the sensor and clean up the install a bit. Very happy with the customer service, hopefully this replacement will last longer. Worked pretty well, the sensor that came with it died in less than 2 weeks but I saw all the reviews saying that so just got an off the shelf Bosch sensor for a Ram 3500 and moved on. Was able to use the signal output wire to data log w pcm logger. Now as of Oct 10th, the display is blank and will not respond to anything. Good ground & 12v switched present at plug. Unplugging sensor doesn't fix it. Pretty disappointed and can't figure out how to get ahold of the seller to get it fixed or replaced.

Was concerned about quailty and effectiveness. Had it installed for awhile lots of passes with it and daily driving. Work great have had 0 issues with it. Would buy again.

As advertised. Easy install. Works great

Installed this wideband over a month ago and still no issues. Wiring is easy. You MUST ground it to the chassis. If not, it will not work properly. Edit: My sensor failed like stated in other reviews. Just ordered a Bosch sensor. The gauge works fine so I'm still happy with the product.

Funciona perfectamente

This kit comes with everything you need and works great with accurate readings. Easy to install, looks good, and even customizable. Both the wires are more than long enough for any mounting location. I have been using this gauge for the whole summer in my Boosted car and it has held up great. Also it's way cheaper than the name brands and I can't see why you wouldn't go with this.

Works very well

Excellent service, build quality looks excellent
