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 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and draws less current than the 4.2 LSU sensor used with AEM’s 30-4100 Wideband UEGO Controller Gauge, which will be superseded to the gauge in August, 2014.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 Wideband UEGO AFR Gauge. The 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. There are two harnesses that connect to the back of the AEM UEGO gauge. The longer harness connects to the UEGO sensor. The shorter harness contains four leads.

Shade tree tuner here. I’ve bought this 3 times and have had two of my friends buy this since the first one worked perfect for me and has been working flawlessly for two years even on E85. Two of my friends (they bought this so I could tune their fueling accurately) had a sensor either dead out of the box, or it lasted a week. One friend has moved the whole kit between three different trucks with no issues. I have one on my turbo Silverado, and bought one for a friend, and now purchased a third one to use as a mobile exhaust sniffer for quick road tunes. This one got installed in the clamp on the exhaust tip, was reading perfectly, then randomly started going from 14.7 straight to three lines after only seeming idle for roughly 10 minutes. When it does that, just go ahead and assume the sensor died.I even thought it was lack of exhaust flow so i put it in one of the factory o2 bungs. Still went from 14.7 to three lines.It’s a fantastic wideband when it works, but aem will not send you a new replacement sensor and if you want a new one through amazon you have to send the whole kit back and get a new one. The replacement sensor is $40, and when it gets here I’m gonna give it one last chance. If it’s dead out of the box I’m finding another kit.

Well here’s the BAD, IT SAYS it comes with a Bosch oxygen sensor. Well that’s NOT true. It’s a Chinese knock off that honestly lasted 10 minutes or less… TWICE ( I returned they 1st gauge kit and I got another 2 days later that lasted 5 minutes).The FIX. after the 2nd o2 sensor didn’t work with either of the gauges ( from the 1st or 2nd kit) . I ordered the BOSCH o2 sensor that SHOULD have come with it . Picture is of the o2 sensor part number you will need.It has been working great now, no issues and it REALLY makes carb tuning much easier. You can see a difference in readings with each 1/4 turn of mixture screws.It’s nice to not only feel the difference as you tune it but actually be able to see the difference on this guage as you change jets, needles and springs.Loving it..With that AEM SHAME ON YOU for putting a JUNK o2 sensor in this kit and try to say it’s Bosch.

A great on dash tool to keep an eye on your AFR, so you don’t burn up your engine!

Put this on a twin turbo car and within 5min of run time it was displaying 3 dashes across the screen. Sensor they send with it is not a Bosch product and has anti seize all over it (could be the cause of the failed sensor)… so if you’re going to buy it here be prepared to spend another $90 on an lsu 4.9 sensor.

High quality gauge with fairly simple install for a intermediate tech. Install is not going to go well for a novice but with some patience and time it can be done.

impossible to get an accurate calibration from the gauge to my ecu,0.0v = 10.004.9v = 19.98wrong. signal sent to the ecu is still off by 20% or more
