The Aem X-series Obdii Wideband Uego Afr Controller Gauge (PN 30-0334) is a game-changer for tuners utilizing piggyback modules or open-source software. It allows for precise AFR monitoring through the factory ECU’s CAN-bus stream, enabling the safest, most accurate, and powerful tuning possible. Validated for use with HP Tuners VCM Suite, this gauge ensures seamless integration with popular tuning platforms.
Unparalleled Accuracy and Performance with OBDII Integration
The 30-0334 X-Series Wideband Gauge features an OBDII pass-through connector and a Bosch 4.9LSU sensor, offering both free-air and factory resistor calibration options. Users can also add 0-5v or RS232 serial output wiring for data logging purposes. This OBDII pass-through functionality replaces the traditional AEMnet stream found in the 30-0300 X-Series Wideband Gauge, providing a more streamlined and integrated solution. The gauge simulates an auxiliary ECU signal, requiring a unique address within the vehicle’s network. AEM’s default OBDII CAN address is compatible with most vehicles, but programmable address adjustments are possible if needed. This includes ECU #, Parameter Identification (PID), Message Identifier, and Bit Rate. Important Note: This gauge requires a CAN-based vehicle for proper operation.
X-Digital Technology: The Fastest Response Time
AEM’s patented X-Digital technology sets the X-Series Widebands apart, boasting the fastest response times among wideband air/fuel ratio controllers. Independent testing against 17 competitors confirmed its superior performance.* This rapid response, achieved through a 100% digital implementation, guarantees no signal loss and full transient response, capturing even the slightest AFR fluctuations.
Why Response Time is Crucial for Tuning
Faster response times translate to improved wideband feedback control, resulting in safer, more powerful, and more accurate tuning. By minimizing dead time, AEM’s X-Digital Wideband Controllers enhance vehicle performance through precise AFR adjustments.
Flexible Calibration: Factory Resistor or Free-Air
The X-Series Wideband Gauges and Inline Controller accommodate the Bosch 4.9LSU sensor, supporting both factory resistor and free-air calibration methods. This allows users to leverage the factory calibration’s precision when the sensor is new and perform free-air calibrations as the sensor ages.** This dual calibration capability provides a perfect balance of simplicity and accuracy.
Understanding Wideband UEGO AFR Controllers
AEM’s Wideband UEGO (Universal Exhaust Gas Oxygen) Controllers are essential tuning tools that provide accurate real-time monitoring of an engine’s Air/Fuel Ratio (AFR). This data is crucial for optimizing engine performance and preventing damage.
The Importance of Accurate AFR Data
Precise AFR readings are vital for engine tuning. Running rich (low AFR, excessive fuel) can lead to power loss, while running lean (high AFR, insufficient fuel) can cause catastrophic engine damage. A wideband AFR controller enables tuners to monitor and adjust AFR, optimizing for power and efficiency. AEM’s wideband controllers offer the reliability and accuracy needed for optimal tuning. Note: The sensor connector cannot be modified due to a calibrated resistor specific to each sensor. Altering the connector will invalidate the sensor’s output.
