FACTORY CALIBRATION RESISTOR OR FREE-AIR CAL, IT'S YOUR CHOICE! X-Series Wideband Gauges and the 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. CAN I CHANGE THE AEM UEGO SENSOR'S CONNECTOR? No. There is a laser-etched, calibrated resistor in the sensor's connector body. This resistor is specifically created for the exact sensor that it is attached to. Modifying this will invalidate the sensor's output. * Independently tested at 360 degrees Product Testing (results reported on August 31st, 2015) against 17 competitor wideband UEGO Air/Fuel Controllers. AEM X-Series Inline with 4.9LSU wideband sensor and AEM X-Series Wideband UEGO AFR Gauge with 4.9LSU sensor recorded the fastest response times. ** Wideband UEGO sensors are wear items and their lifespan is determined by many factors including contamination from leaded fuels, automotive fluids, particulates, mechanical or thermal shock and from being unheated and exposed to the exhaust stream. Free-air calibration may correct drift as a sensor ages, but it is recommended that they are replaced as part of your vehicle's maintenance program. When performing free-air calibration, please follow the procedure outlined in the instruction manual.
