AEM Digital Wideband UEGO AFR Gauge - No SensorOur World famous Wideband O2 air fuel ratio UEGO gauge features a digital LED display and sweeping LED 'needle' that changes colors as AFR changes from rich to lean. A 52mm (2 1 16") gauge housing ensures that it will fit in most gauge pods and can be remotely mounted virtually anywhere. All AEM digital gauges feature a 0 5v analog output for use with data loggers and almost any engine management system. Each gauge comes with black and silver bezels

Our World-famous Wideband O2 air/fuel ratio UEGO gauge features a digital LED display and sweeping LED 'needle' that changes colors as AFR changes from rich to lean. A 52mm (2-1/16") gauge housing ensures that it will fit in most gauge pods and can be remotely mounted virtually anywhere. All AEM digital gauges feature a 0-5v analog output for use with data loggers and almost any engine management system. Each gauge comes with black and silver bezels and black and white faceplates for multiple color combinations and a custom look (a black Lambda faceplate and black and white Air/Fuel Ratio faceplates). The Bosch UEGO sensor gives the controller its speed and accuracy. The Bosch 4.9 LSU sensor used in the 30-4110 AEM Wideband UEGO AFR Controller Gauge has a faster light off time and draws less current than the 4.2 LSU sensor used with AEM’s 30-4100 Wideband UEGO Controller Gauge, which will be superseded to the 30-4110 gauge in August, 2014. The 4.9 LSU sensor features the same fuel compatibility as the 4.2 LSU and NEVER requires free-air calibration when used with AEM’s 30-4110 Wideband UEGO AFR Gauge. The 30-4110’s 4.9 LSU sensor uses a different connector than the connector used with the 4.2 LSU sensors included with the original 30-4100 gauge controller. The sensors are not interchangeable between the two gauge controllers in any way, including changing connectors on the gauges. The Wideband O2 air/fuel ratio UEGO gauge is a must if you want to maximize your engine's power and safety. When tuning an engine, accurate air/fuel ratio data is critical because running with too rich of an AFR can cause a loss of power, and running a lean AFR can result in serious engine damage. AEM's digital Wideband AFR UEGO gauge can quickly alert you to even a .1 change in air/fuel ratio and provide enough time to shut down an engine before damage occurs. Using the above sensors ensures that the factory sensor calibration is accurate and that the controller performs optimally. The use of any non-approved sensor may affect the controller's operation, and will void the warranty of the 30-4110NS. The new 30-4110NS Wideband UEGO Controller Gauge has the same display range and includes the same calibrated scale on its 0-5v output (10-20 AFR), for data logging or closed-loop feedback control when used with a standalone ECU. A serial output (RS232) is also included for outputting AFR values for data logging and feedback control. Gauge Readouts :

  • Center LED Readout Displays Gasoline Values from 10 to 18 :1 AFR
  • Outer LED Ring Displays Gasoline values from 11 to 16.75 :1 AFR
  • 0-5V Output Gasoline values from 10 to 20 :1 AFR

  • 0-5V Output Lambda values from .68 to 1.36
  • Center LED Readout Displays Lambda values from .68 to 1.23

10/10 work mouse
Size: One Size
Lasts forever. Been my work mouse for years. Batteries last forever in it. Cheap enough to keep a spare in my laptop bag for when I need to travel for work. Not a gaming mouse, but a serviceable work mouse. But not tiny like a "travel mouse" so it isn't uncomfortable to use. A man can use one without his hand cramping up.

Comfortable Seating
Color: Black, Style: Classic
I honestly didn’t expect this chair to be this comfortable, but it has exceeded my expectations in every way. I sit at my desk for long hours every day, and the adjustable air-pump lumbar support has been a total game changer. I love that I can fine-tune the firmness depending on how my back feels that day. My lower back pain has noticeably improved since switching to this chair.The seat is wide, thick, and very supportive without feeling stiff, which makes long work sessions much more comfortable. The armrests are another big plus—they adjust in so many directions that I can always find the perfect position for typing, reading, or relaxing. The chair feels extremely sturdy and well built, and it gives me confidence knowing it supports higher weight without wobbling.Assembly was straightforward and took about 20 minutes. Overall, this chair feels premium, comfortable, and thoughtfully designed. I would absolutely recommend it to anyone looking for a reliable, all-day office chair.

Nice chair, w/ good cust support
Color: Black, Style: Classic
I apologize for length, but if I am doing a review for other people I assume you want to have as much info as possible to make a decision. I feel this chair is for tall/fat/both so will review it as such. At 6’4” @ 350lbs I fit into both, but reviewing based upon my body, yours is different so adjust according. TLDR – Would buy again, cavernous comfy chair with excellent customer support. Only personal dings against chair are the back could be taller, but added back due to support. Parts + Fit/Finish + Assembly: The parts have some heft and feel solid as expected for a chair designed for heavy people. Material and stitching look proper and I see no flaws. My box was beat to hell and ripped opened at one point. Packing material took the hit and did its job as the items were unaffected. The gas cylinder for the chair was missing and assume lost during shipping. (see customer service). Assembly was standard office chair fare with simple and clear instructions. Wheels / Height / Controls: I normally wouldn’t think of mentioning wheels, but it’s different than expected. They are good, maybe too good. A slight kick to push you back on wood floors sends you flying. The height adjustment for me is good/standard. At full height my feet are flat on the floor and where I would have the chair even if it went higher. My wife (5’6”) at that height is about 2.5 inches above the floor. Taller people than myself may wish for more height. Chair controls are standard fare and operate smoothly Seat: It’s large and with the arms is there is nothing even close to your hip/legs. I can put my fist on my hips and my arms barely touch the chair arms. This is why you are thinking of this chair, and for that you will not be disappointed. The seat is not pillow soft and IMHO a little firmer than I liked at first, but after a few days got broken in or I adjusted. I am a programmer + gamer so spend a lot of time in the chair for hours on end. Comfortable and no complaints at all. Seat depth for me is ~1” from my knee and good with roughly 20.5” usable butt/thigh length. That should be fine for big/tall but may be a bit much for big/short. Measure your current chair and decide from there. Back: The back lets the chair down a bit for me, the big/tall user, as the target seems to be big/short users. The back ends just below my shoulder-line. That obviously means no leaning my head back and the headrest is squarely on my shoulder blades. Not uncomfortable, but I’d prefer a taller back. For me personally I’d like it to be extended 4”, but that would likely be an issue for shorter users. I feel if the manufacturer increased the back by 2 inches it would be an ideal compromise for all users. The chair has an inflatable lumbar support, which I did not use as I personally find those uncomfortable. Also note the chair is designed for a more proper posture with a 90deg back and not a more relaxed 100-110deg. Neither pro/con as personal preference. Arms: The design of the arms being supported by rear only as mentioned earlier allow for an abundance of hip/thigh space. This is an excellent ergonomic design with a potential caveat. More stress will be placed upon the connection/joint. The joint for this chair is just shy of 4” so seems beefy but only time will tell if it holds up to the lateral force of leaning on it while reading. My chairs tend to last 5-7 years, due to the right arm feeling wobbly or the chair leaning to the right. The arm adjustments provide a nice front/back of ~3”, from touching chair back to 3” gap between chair/armrest. The height is similar and also moves the armrest forward about another 2”. At full forward/up the armrest are higher than I like so should easily accommodate taller users. Customer Service My chair was missing a part that I suspect was lost during shipping due to box condition. I contacted them Sun (7/20/2025 @ 1201). At 2228 that night I received a response that they acknowledged the issue and gave a tracking order for the missing part. The part arrived Mon 7/28 and gave a few days to test it out for review Fri (8/1). Obviously you don’t want an issue, but if an issue arises how a company handles it tells you a lot IMHO on how they feel about their product. I am very pleased with their handling of the matter.

Great Chair
Color: Black, Style: Classic
The durability, recline, noise, fit, and appearance, and stability of the chair were all fantastic. As someone of a shorter height, the backrest which is normally way to high or short for my head fits perfectly. The chair itself is easy to assemble and very comfortable to sit in for long hours. I tend do a lot of work at home and this chair feels very comfortable without feeling the need to get up. The chair looks great set up in my office and is honestly a great office chair. For moving around a room, the wheel guides across my carpet very smoothly with struggling unlike my previous chair which would need a heavy push. Not only that, the chair is noiseless which is a plus for people who get bothered by little sounds when moving around. The fit could honestly fit anyone of any size as the chair itself is quite wide and roomy for me. The seat is also made up of faux leather and feels well stitched and quite durable.
