Product Description
The AEM X-Series Wideband UEGO Air/Fuel Ratio Sensor Controller Gauges have patent pending X-digital technology that makes them the fastest responding wideband air/fuel ratio controller in independent testing against 17 other wideband UEGO controllers. This OBDII version provides tuners who are using piggyback tuning modules or open source software with the ability to view AFR through the factory CAN-bus stream that is output by the factory ECU, and deliver the most accurate, safe and powerful tune. The Gauge is validated to work with EFILive, HPTuners and DashDaq software.Patented technology makes this the fastest responding AFR controllerIncludes a highly accurate Bosch 4.9LSU sensorDisplays AFR values in hundredths of a %User configurable display via button on the gaugeOptional 0-5V and RS232 outputs for data logging and feedback controlThe X Series Wideband UEGO AFR Sensor measure 52mm in diameter and has a slim depth less than one inch with an ultra slim cup of .200 inches increases this gauges application base and potential mounting locations. As standard the gauge is supplied with a black face and bezel. An accessory kit is available separately which includes a white face and silver bezel to change the look of the gauge. The gauge has a configurable display via buttons on the face of the gauge these allow you to change the air/fuel ratio values for different fuels, lambda or O2%, change the display to show either 3 or 4 digits, perform a free air calibration as the sensor gets older and change the CAN message if linking multiple controllers or gauges.This kit has a black bezel and black dual faced faceplate for air/fuel and lambda. An auto dimming feature is also included, comes with locking connectors that ensure a positive connection is made between the harnesses and gauge and the new single board design adds to the durability of the gauge.The gauge comes with a 0-5v and RS232 seriel port output for feed back and data logging and an AEMnet output for data logging. AEMnet allows additional X Series wideband controllers to be daisy chained together for recording air/fuel ratios in multiple cylinders.The system supports vehicle/system voltages up to 16V, and can be used on electronic fuel injection or carbureted applications and dynamometers in applications using petrol, methanol, ethanol, diesel, propane or LPG.
