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)

Great customer service from the seller!

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

Never failed on me.

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.

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.

I purchased this product in April of last year. I just recently put it on a motorcycle I have owned for thirty five years (1986 Yamaha Vmax ). Within one hour of driving it the whole front fell off the gauge. I am an accomplished motorcycle mechanic. I know this product is out of warranty but I felt it important to tell you about this mishap so that you and your company can make changes to fix this problem. Before the face fell off the gauge it worked perfectly.

Works fine and has been working on a C4 corvette. I've been tuning a 406 wth a mild cam and seems to to accurate. Engine seem lean when guage says it's lean. It's respond quick and I'd 100% buy this again.
