AEM's X-Series Inline Wideband UEGO Air/Fuel Ratio Controllers redefine the standard for accurate and fast response in air/fuel ratio monitoring. Employing patented X-Digital technology (Patent 9,575,030), these controllers are the fastest responding wideband air/fuel ratio controllers in independent testing, making them a top choice for those who prioritize precision in engine tuning.

Cutting-Edge X-Digital Technology: The X-Series Controllers' patented technology allows for the most accurate reading of air/fuel ratios. This advanced digital implementation ensures no loss of signal fidelity and full transient response, capturing even the slightest fluctuations in AFR for comprehensive engine tuning.

Optimized for Versatility and Ease of Use: The X-Series Inline Controller is housed in a weather-resistant, low-profile enclosure with status LEDs, making it suitable for a variety of applications. It's ideal for users who require fast response times for data logging or feedback control, without the need for a gauge display. The controller includes a Bosch 4.9LSU sensor known for its reliability and precision.

Multiple Output Options for Enhanced Compatibility: With a 0-5v and RS232 Serial Port output, plus an AEMnet (CANbus) output, this controller is versatile for feedback control and data logging. It can be daisy-chained with multiple controllers for detailed recording across up to 16 cylinders. This adaptability makes it suitable for EFI or carbureted applications, as well as dynamometers in various fuel types, including gasoline, methanol, ethanol, diesel, propane, and CNG.

User-Selectable Calibration: The X-Series Wideband supports both factory calibration resistor and free-air calibration methods, offering flexibility for users to choose based on sensor age and application. This feature ensures ongoing accuracy and longevity of the sensor.

Why Choose an AEM Wideband UEGO Controller? AEM's Wideband UEGO Controllers are powerful tools for tuning engines. Accurate AFR data is crucial to prevent power loss from rich mixtures and engine damage from lean mixtures. These controllers provide the precise data needed for optimally tuning the air/fuel ratio, ensuring maximum power and efficiency.

In conclusion, the AEM X-Series Inline Wideband UEGO Air/Fuel Ratio Controllers are essential for anyone serious about accurate engine tuning. They offer the fastest response, versatility, and reliable performance, making them an indispensable tool in the arsenal of any performance enthusiast or professional tuner.
