The 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. AEM's default OBDII CAN address will work with most popular vehicles and adjustments should not be necessary. However, AEM has provided OBDII address programmability through the buttons on the gauge face if a different address other than the default address is required, allowing users to program ECU #, Parameter Identification (PID), Message Identifier, and Bit Rate.

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.. ** 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.. 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.. * Independently tested at 360° 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.. 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.. 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.. X-Series Wideband UEGO AFR Controllers Gauge were fastest responding wideband air/fuel ratio controllers in an independent test vs. 17 competitors wideband AFR controllers. 0-5V & RS232 output for data logging and feedback control, AEMnet (CANbus) for data logging and daisy-chaining multiple controllers up to 16 cylinders. Factory calibrated resistor does not require free-air calibration, but technology allows for free-air calibration as sensor ages if user desires. Black bezel and black dual faced faceplate included (gauge only, silver bezel/white gauge option sold separately, PN 30-0300-ACC). User configurable display via buttons on the gauge face for changing AFR values, Lambda and O2%, and 3- or 4-digit display. X-Series AFR Gauge.

AEM was founded in 1987 by John Concialdi (J.C.) and Bob Sullivan as a tuning performance shop. The shop focused on vintage automobiles and the latest trends in street racing modified imports. With it's location in Compton California, AEM was embedded in the tuner market from the very beginning. It was a matter of being in the right place, at the right time, with the right technical knowhow. Between J.C. and Sullivan, AEM had two important advantages. Technical engine knowledge and massive creativity fueled by an unbridled passion to make things go faster. When it came to understanding air flow through an engine, few had more experience than Concialdi. He managed the R&D department for Weber Carburetors for North American aftermarket applications the previous 10 years. By 1993 when the shop relocated to Gardena California, AEM had the reputation as a modifier of choice. The business had grown so much that at times it ran 24 hours a day. Racers depended on AEM to have cars ready for the next street race or sanctioned event. Cars and drivers sporting AEM’s bright yellow logo became famous in the street racing scene for one consistent reason, they won races. AEM’s first glimpse of mainstream notoriety came when cars tuned by their shop won at the “Battle of the Imports”. This highly contested shoot-out landed AEM on the cover of Turbo Magazine and Sport Compact Magazine. Many of the most visible drivers in import street racing ran cars modified by AEM. This included names like Adam Saruwatari, Tony Fuchs, Brian Kim and Darin Ishitani, Archie Medrano, Russ Matuseavich, Abel Iberra, Miles Bautista, E.T. Saffon. AEM developed one of the first Packaged Air Induction Systems. It's design came from their experience in dyno testing, understanding intake energy dynamics and racing at the Battle of the Imports. AEM’s presence in the tuner movement and its proximity to Nissan, TRD and Honda allowed them a unique opportunity. There was an advantage to living side by side with racers and working with OES engineers. AEM was able to understand both the practical and theoretical side of engine performance. AEM's first air intake kit was offered for sale in 1994 as a "Do-It-Yourself" upgrade for the Honda CRX. This intake proved to be the beginning of a whole new tradition. People could suddenly purchase affordable cars and modify them for increased torque and horsepower. AEM has been a leader in the development of precision tuned induction systems since the Battle of the Imports. Today, the Company’s induction systems number in the hundreds. AEM is still the one to beat.
