No free air sensor calibration required ever.Bosch 4.9 LSU wideband sensor and weld-in bung included PN 30-4110.Interchangeable black and white faceplates included for customizing gauge appearance.The longer harness connects to the UEGO sensor. There are two harnesses that connect to the back of the AEM UEGO gauge. 1 change in air/fuel ratio and provide enough time to shut down an engine before damage occurs. 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.ĪEM’s digital Wideband AFR UEGO gauge can quickly alert you to even a. 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 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 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 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and draws less current than the 4.2 LSU sensor used with AEM’s 30-4100 Wideband UEGO Controller Gauge, which will be superseded to the gauge in August, 2014.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 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). A 52mm (2-1/16″) gauge housing ensures that it will fit in most gauge pods and can be remotely mounted virtually anywhere.Īll AEM digital gauges feature a 0-5V analog output for use with data loggers and almost any engine management system. 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.
