Description

AEM Digital Wideband UEGO Gauge 4.9 LSU Sensor Kit 30-4110Our 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and draws less current than the 4.2 LSU sensor used with AEM’s 30-4100 Wideband UEGO Controller Gauge, which will be superseded to the 30-4110 gauge in August, 2014.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.

Nice, BUT a few mounting holes would have made it 5 stars!
Color: Black*2
These seem to be fine but since I have to use this to hold a power brick to a wood joist which is NOT smooth, the included adhesive back is not something that will hold securely! I ended up have to screw two wafer head screws through the rubber backing and into the joist to hold the holder to the wood joist securely. If they put some thought into the design, it would have been nice, if they had incorporated a few mounting holes, which would have taken care if this being mounted to items that are not smooth such as a wood joist or other rough surfaces!

Tight squeeze for a 240w but works well
Color: Black
This works pretty well. It was a little bit of a tight squeeze for a 240w brick, but it's stable at least. Strong adhesive

Great for a gaming laptop!
Color: Black, Size: 1.37" without hook
Great product is you want to mount any size laptop under your desk. I used it for my Alienware gaming laptop and it's fantastic! The three points of contact hold the laptop securely, while allowing maximum airflow for the fans. The three "clamps" are rock solid and will definitely outlive the laptop. The installation was simple and easy, just need a drill.

under desk laptop system
Color: Black, Size: 1.37" without hook
Reclaimed real desk space with this one. The mount holds the laptop securely underneath without any vibration or creaking and the installation required no drilling — clamped cleanly to the desk edge. The ventilation spacing is generous enough that thermals stay reasonable even under load. Works with a solid range of laptop sizes and the adjustment mechanism is easy to use. If your laptop spends most of its time docked this is the cleanest way to get it out of the way.

Works great, but pads are peeling.
Color: Black, Size: 1.37" without hook
Works for what I needed, which was to mount my work laptop to the side of my desk. However, the rubber pads started peeling the first day. I tried clamping them down overnight, but they still ended up peeling up. They haven't come off completely and are still working, though. I may have to glue them down.
