Description
AEM’s X-Series Wideband Air/Fuel Ratio Sensor Controllers are built upon unique, patented X-Digital technology (Patent 9,575,030), making them the fastest responding wideband air/fuel ratio controllers in independent testing*.
• X-Series Wideband UEGO AFR Controller Gauges were the fastest responding wideband air/fuel ratio controllers in an independent test vs. 17 competitor wideband AFR controllers
• User-configurable display for changing between AFR, Lambda, and O2%, and 3- or 4-digit display
• Black bezel and black double-sided faceplate included (silver bezel/white faceplate option sold separately, PN 30-0300-ACC)
• Patented X-Digital wideband technology (Patent 9,575,030)
• Factory calibrated resistor does not require free-air calibration, but can be free-air calibrated
• Auto-Sensor Detection between AEM FAE and Bosch LSU 4.9 wideband sensors
• Compatible with supply voltages up to 16V
• 0-5V & RS232 output for data logging and feedback control, AEMnet (CANbus) for data logging and daisy-chaining multiple controllers up to 16 cylinders
• 52mm gauge diameter and slim 0.825″ gauge depth(Gauge cup depth only .200″ deep)
• Auto-dimming feature
Information:
FACTORY CALIBRATION RESISTOR OR FREE-AIR CAL, IT’S YOUR CHOICE! The X-Series Wideband Gauge and X-Series Inline Controller support the popular 4.9LSU sensor and can utilize both the factory calibration resistor and free-air calibration methods**. This allows users to take advantage of the precise factory resistor calibration when a sensor is new but then allows for free-air calibrations if the user desires when the sensor ages. It’s the perfect marriage of simplicity and accuracy! WHAT IS A WIDEBAND UEGO AIR/FUEL CONTROLLER? AEM’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. WHY USE A WIDEBAND AIR/FUEL CONTROLLER? Accurate 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 has a comprehensive line of highly accurate, reliable wideband air/fuel controllers that can help ensure your vehicle is optimally tuned.
