AEM Electronics Digital Wideband UEGO AFR Controller Gauge (Sensor Not Included) - Silver, Silver

The AEM Electronics Digital Wideband UEGO AFR Controller Gauge - Without Sensor is a powerful, cost-effective tuning tool that quickly and accurately monitors the Air/Fuel Ratio (AFR) of your engine, in an all-in-one wideband UEGO AFR controller and gauge.Controller gauge and hardware sold without wideband sensorWeld-in bung includedNo free air sensor calibration is required with approved sensors52mm (2-1/16") gauge housing0-5v analogue output (10-20 AFR range only)RS232 Serial OutputAccurate 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's renowned Digital Wideband O2 AFR UEGO Gauge combines accuracy, speed and control with an easy to read, digital LED display and sweeping LED "needle", that changes colours as AFR changes from rich to lean.Constructed from high-quality precision AEM/BOSCH components, this AFR controller gauge is specifically calibrated for use with the recommended sensor and the installed connector, which also features a specific laser-etched calibrated resistor in the sensor connector body, to ensure the AEM Digital Wideband UEGO AFR Controller Gauge maintains its accuracy.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 analogue 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 colour 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 with this AEM Wideband UEGO AFR Controller Gauge has a faster light off time and draws less current than the previous AEM Wideband UEGO Controller Gauge, but offers the same fuel compatibility without the need for free-air calibration, which is often required by other brands AFR sensors.This UEGO AFR Controller Gauge is available without a wideband sensor, Giving users the option to source their own compatible Bosch 4.9LSU sensor and benefit from the potential cost savings. Following extensive testing of many available sensors, with varying degrees of quality, cost and performance, the AEM recommended sensors below will ensure the factory sensor calibration is accurate and that the controller performs optimally.AEM only recommends the following approved sensors for reliable use with the AEM30-4110NS *ManufacturerPart NumberDescriptionAEM30-2004Bosch LSU4.9 (950mm)Bosch17025Bosch LSU4.9 (950mm)Walker250-25036Bosch LSU4.9 (950mm)Walker250-25075Bosch LSU4.9 (325mm)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.AFR VALUE RANGE BY FUEL TYPES:Center LED Readout Displays Gasoline Values from 10 to 18 :1 AFROuter LED Ring Displays Gasoline values from 11 to 16.75 :1 AFR0-5V Output Gasoline values from 10 to 20 :1 AFR0-5V Output E85 values from 6.6 to 13.2 :1 AFR0-5V Output Ethanol values from 6.14 to 12.3 :1 AFR0-5V Output Methanol values from 4.4 to 8.8 :1 AFR0-5V Output Lambda values from .68 to 1.36Center LED Readout Displays Lambda values from .68 to 1.23Outer LED Ring Displays Lambda values from .75 to 1.14Please note: The use of any non-approved sensor may affect the controller's operation and will void the warranty of this AFR controller gauge.
