AEM X-Series OBDII Wideband UEGO AFR Sensor Controller Gauge

Additional wiring for a 0-5v or RS232 Serial output can be added by the user for outputting to a data logger. This OBDII pass-through capability replaces the traditional AEMnet stream available in the 30-0300 X-Series Wideband AFR Gauge Controller.OBDII CAN-bus OUTPUTThe OBDII output simulates an auxiliary ECU signal when plugged into a vehicle's OBD port, which requires a unique address from the other ECUs already on a vehicle's network.
X-Series Wideband UEGO AFR Sensor Controller Gauge with OBDII Connectivity. Includes: X-Series Wideband Controller Gauge, Bosch LSU 4.9 Sensor, Wiring Harnesses, Black Bezel, Black AFR/Lambda Faceplate, OBD2 Cable & O2 Sensor Bung
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.
