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)

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.

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.

Hooked up the gauge for the first time today. Had sensor hooked up before adding power and ground. Gauge came alive at 14.7 and then climbed to full lean. Which seems correct since the engine wasn’t running. I started the engine and nothing. I tried more throttle and not a blip of change. I verified good power and ground. If the company can reach out to me about warranty for the sensor atleast, I’d appreciate it before I return the whole setup. Or if they have any in-depth T/S. I was hopeful and and thought I’d get lucky with a good setup, but it seems the reviews are accurate and the sensor is junk

As advertised. Easy install. Works great

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.

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).

Works Good

After buying expensive wideband gauges, then finding these I figured it was worth a try. Since that first try I've bought 3 or 4 of them for different vehicles. Only had an issue with a sensor on one I purchased. Messaged the company and instead of just sending me a new sensor, they sent a whole new gauge kit within 2 days. Pretty solid product with great customer service.

Excellent service, build quality looks excellent

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.
