Designed for professional tuners and enthusiasts, these 52mm gauges offer fast sensor response, 0-5V analog outputs for seamless data logging, and customizable bezels and faceplates. Perfect for millennial managers who demand both performance insights and style in their ride. ## Description AEM's 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and draws less current than the 4.2 LSU sensor used with AEM's 30-4100 Wideband UEGO Controller Gauge, which will be superseded to the 30-4110 gauge in August 2014.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. | AEM's Digital Boost Display Gauges combine unsurpassed accuracy, speed and control with an easy-to-read digital LED interface that displays boost in 1 PSI increments, and a sweeping LED "needle" that lines the edge and moves as boost from 0 to up to 50 PSI. The boost gauge's digital readout will automatically increase and decrease in intensity due to the built in ambient light sensing photocell. AEM's digital boost gauges include a 0-5v analog output for use with data loggers and virtually any engine management system, such as the Infinity ECU, Series 2 EMS or AQ-1 Data Logger, making it the perfect solution for users who need to monitor and data log boost at high RPM on tuned engines. Review: Awsome buy - So these things worked out perfectly , I heard from many that the A/F meter breaks on the sensor side hope mines last for quite some time , my mec did a great job installing it , its fashionable and clean , reads perfectly , turns out my car has been running rich time to tune Review: Works great - 2 years later and still working. The wideband is like all others it only gives a rough estimate. Its off a little according to my dyno tuner. id recommend these they are pretty nice. ## Features - 2 popular AEM gauges in a convenient combo set.
