AEM Digital Wideband UEGO Air/Fuel Ratio Gauge with 4.9 LSU Sensor 30-4110

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 UEGO sensor gives the controller its speed and accuracy. The 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and draws less current than the 4.2 LSU sensor used with AEM's 30-4100 Wideband UEGO Controller Gauge, which will be superseded to the 30-4110 gauge in August 2014.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. LSU 4.9 Sensor - Interchangeable bezels and face included 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. NOTE: The 30-4100 Wideband UEGO Gauge Controller that uses the 4.2 LSU sensor will be superseded to the 30-4110 Wideband UEGO Gauge Controller that uses the 4.9 LSU sensor in August 2014. Instructions for the 30-4100 will still be available in the Instructions tab after this change. 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 4.9 LSU sensors in our wideband controllers. Our sensors are individually laboratory-calibrated and never require free air calibration!

• 52mm (2-1/16") gauge housing

The AEM Digital Wideband UEGO Air/Fuel Ratio Gauge combines a high-accuracy wideband air/fuel ratio controller with an easy-to-read digital gauge. Part number 30-4110 uses a 4.9 LSU wideband sensor to deliver fast, precise AFR monitoring for engine tuning, performance driving, and engine protection. The digital LED display is paired with a sweeping LED needle that changes color as the mixture transitions from rich to lean, allowing important air/fuel changes to be recognized quickly.

Designed for flexible installation, the AEM 30-4110 uses a standard 2-1/16-inch gauge format that fits most gauge pods and can be remotely mounted in a convenient location. A built-in 0-5-volt analog output supports data logging and connection to compatible engine management systems across a 10-20 AFR range. The included 4.9 LSU sensor is laboratory calibrated and does not require free-air calibration during normal use. It is not interchangeable with the 4.2 LSU sensor or connector used by the earlier AEM 30-4100 controller.

The gauge includes interchangeable black and silver bezels along with black and white faceplates, allowing the appearance to be matched to the vehicle interior or other instruments. The 4.9 LSU sensor and weld-in bung are included for installation. Accurate AFR information is essential when tuning because an excessively rich mixture can reduce power, while a lean mixture may contribute to severe engine damage. The AEM wideband gauge provides rapid visual feedback to help identify potentially harmful air/fuel changes.
