X-Series Wideband are the fastest responding wideband air/fuel ratio controllers in independent testing against 17 other wideband UEGO air/fuel controllers.* The controller’s high speed, patented, 100% digital implementation ensures no loss of signal fidelity and full transient response, making it able to identify the slightest fluctuations in AFR and output them in full value. X-Series Wideband Gauges and the X-Series Inline Controller support the popular Bosch 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!  This OBDII pass-through capability replaces the traditional AEMnet stream available in the 30-0300 X-Series Wideband AFR Gauge Controller.  Additional wiring for a 0-5v or RS232 Serial output can be added by the user for outputting to a data logger.

X-Series Wideband UEGO Controller Features:
Patented X-Digital Technology makes it the Fastest Responding Wideband AFR Controller (Patent # 9,575,030)
OBDII pass-through provides AFR readings through the factory ECU CAN-bus – Ideal for users with piggyback programmers or open-source tuning software
Includes Bosch 4.9LSU wideband UEGO sensor and OBDII pass-through connector
Use the factory 02 calibration or free-air calibrate using buttons on the faceplate
Compatible with vehicle/system voltages up to 16V
Optional outputs for 0-5V & RS232 for data logging and feedback control (requires wiring)
Can display AFR values in hundredths of %
52mm gauge diameter and slim 0.825” gauge depth
Gauge cup depth only .200” deep!
Auto-dimming feature
User configurable display via buttons on the gauge face for changing AFR values, Lambda and O2%, 3- or 4-digit display, and OBDII output settings (if necessary)
Black bezel and black dual-faced faceplate included (silver bezel/white gauge option sold separately, PN 30-0300-ACC)
Locking connectors
Step 7: Once you receive your upgraded ECM, install it back into your vehicle and start tuning!

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.
