But just the right amount of air will truly make a car jump off the line.
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. The Wideband O2 air/fuel ratio UEGO gauge is a must if you want to maximize your engine's power and safety. The sensors are not interchangeable between the two gauge controllers in any way, including changing connectors on the gauges. 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 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 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 Bosch UEGO sensor gives the controller its speed and accuracy.
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). All AEM digital gauges feature a 0-5v analog output for use with data loggers and almost any engine management system. A 52mm (2-1/16") gauge housing ensures that it will fit in most gauge pods and can be remotely mounted virtually anywhere. 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. Modifying this will invalidate the sensor’s output. This resistor is specifically created for the exact sensor that it is attached to. There is a laser-etched, calibrated resistor in the sensor’s connector body.

Our sensors are individually laboratory-calibrated by Bosch and never require free air calibration!ĬAN I CHANGE THE AEM UEGO SENSOR’S CONNECTOR? We use Bosch 4.9 LSU sensors in our wideband controllers. 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. Some of our competitors require that you frequently perform a free-air calibration procedure to calibrate their O2 sensors. AEM has a comprehensive line of highly accurate, reliable wideband air/fuel controllers that can help ensure your vehicle is optimally tuned. 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. 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. WHAT IS A WIDEBAND UEGO AIR/FUEL CONTROLLER?ĪEM'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.Īccurate AFR data is critical when tuning an engine. Instructions for the 30-4100 are still available in the Instructions tab. The 30-4110 Wideband Controller Gauge is cosmetically identical to the 30-4100. NOTE: The 30-4100 Wideband UEGO Gauge Controller that uses the Bosch 4.2 LSU sensor has been superseded to the 30-4110 Wideband UEGO Gauge Controller that uses the Bosch 4.9 LSU sensor.
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’s legendary Digital Wideband O2 AFR UEGO Gauge is a wideband UEGO air/fuel ratio controller (AFR) and gauge in one.
