AEM Electronics Digital Wideband UEGO Gauge without Sensor (30-4110NS)AEM's part number 30 4110NS Wideband UEGO air fuel ratio Controller Gauge is sold without a wideband sensor. This allows users to source a Bosch 4. 9LSU sensor separately to potentially save money.

AEM's part number 30-4110NS Wideband UEGO air/fuel ratio Controller Gauge is sold without a wideband sensor. This allows users to source a Bosch 4.9LSU sensor separately to potentially save money.

AEM’s legendary Digital Wideband O2 AFR UEGO Gauge is a wideband UEGO air/fuel ratio controller (AFR) and gauge in one. It unites accuracy, speed and control with an easy to read, digital LED display and sweeping LED “needle” that changes colors as AFR changes from rich to lean.

AEM tested many sensors with the 30-4110NS, including popular inexpensive knockoff sensors, and determined that only the following sensors will deliver reliable performance:

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.

WHAT IS A WIDEBAND UEGO AIR/FUEL CONTROLLER?
AEM's Wideband UEGO (Universal Exhaust Gas Oxygen, pronounced “You-Way-Go”) Controllers are powerful, cost effective tuning tools that allow users to accurately monitor the Air/Fuel Ratio (AFR) of their engine.

WHY USE A WIDEBAND AIR/FUEL CONTROLLER?
Accurate AFR data is critical when tuning an engine. Running rich (very low air/fuel ratio, excessive fuel) can cause a loss in power, while running too lean (very high air/fuel ratio, not enough fuel) may result in serious engine damage. Using a wideband air/fuel controller during the tuning process allows you to monitor AFR and adjust tuning parameters to optimize them for maximum power and efficiency. AEM has a comprehensive line of highly accurate, reliable wideband air/fuel controllers that can help ensure your vehicle is optimally tuned.

WHAT IS FREE-AIR CALIBRATION?
Some of our competitors require that you frequently perform a free-air calibration procedure to calibrate their O2 sensors. This process involves removing the sensor from the bung while still connected to the controller device, then waving the sensor in the air so it can read atmospheric O2 levels. We use Bosch 4.9 LSU sensors in our wideband controllers. Our sensors are individually laboratory-calibrated by Bosch and never require free air calibration!

CAN I CHANGE THE AEM UEGO SENSOR’S CONNECTOR?
No. There is a laser-etched, calibrated resistor in the sensor’s connector body. This resistor is specifically created for the exact sensor that it is attached to. Modifying this will invalidate the sensor’s output.

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 discontinued 30-4100 Wideband UEGO Controller Gauge. 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, discontinued 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.

Absolutely the BEST hold for headphones!!
Style: Studio-Grade White – One Pack
Perfect...just needed something easy to use and gentle on my headphones to get them out of the way when not in use. I have purchased several different holders from "TotalMount" and all their stuff is top quality high grade. Nothing flimsy here. I would highly recommend. Holder adheres to any surface and removes without leaving a mark. Sticks using command strips (4 strips for super secure hold) and has a smooth grey silicon liner that looks very mod. I purchased the white hold. I would most definitely purchase again.

Simple and easy
This headphone holder is excellent! It’s super easy to install without screws or permanent adhesives, so it won’t damage my walls. The mount feels very sturdy and holds my headphones securely, and the sleek black design looks great in my studio setup. A simple, practical solution for keeping headphones organized and within reac

A good hanger
There is not much to say in a review for a headphone hanger. It is nice that it uses four command strips so you can buy replacement strips when needed. It would have been nice to know a setup for the strips. There are four areas for the strips per hook. The instructions want you to use all four but that seems like overkill to me. Either way, it works nice and looks nice. I would suggest splurging on the silicone padded one just so that you have a little more protection for your headphones as well as the grip that the silicone adds.

Durable and 3M command strips
After I was back and forth with a few different mounts I finally took the leap and bought these as they are small enough but mighty. The mount is wide enough to not have to squeeze on my beat headphones and they rest on the silicone area. The best part is they come with 3M strips so if I want to relocate them I can buy replacement strips to remove and move them elsewhere without compromising quality regarding adhesion. Damage free and easy to use. Totally worth the buy to me!
