The AEM X-Series Professional Dual Channel Lambda Controller features a CNC aluminum IP67 rated enclosure with an
Autosport locking connector suitable for a professional motorsport environment. The AEM inline controller is ideal for all
vehicles including carbureted applications and engine dynamometers. A 0-5V analog output is included and can be used
with data loggers or aftermarket ECUs including the AEM Infinity Engine Management System (EMS). In addition, an
AEMnet (CAN bus) is also available for logging or mixture control purposes. Bosch LSU4.9 sensors are supported but not
The 30-0350 X-Series PRO Dual Channel Lambda Controller is verified to work with HPTuners, EFILive and DashDaq, with more applications being validated. Please check the CAN abilities of your third party device and the instruction manual for CAN message structure
The X-Series PRO Dual Channel Lambda Controller does NOT include any additional wiring for a 0-5v or CAN net output can be added by the user for outputting to a data logger. You must wire yourself or have a professional offer wiring services.
The controller includes a 0-5v analog output, and an AEMnet (CANbus) output for data logging. AEMnet allows additional X-Series Wideband Controllers to be daisy chained together (up to 16 cylinders) for recording AFR in multiple cylinders. It supports vehicle/system voltages up to 16V, and can be used on EFI or carbureted applications, and dynamometers in applications using gasoline, methanol, ethanol, Diesel, propane and CNG.
X-Digital wideband technology gives these controllers the ability to read and report values that other controllers do not, which can deliver more optimized engine tuning and a safer overall operating condition. The controllerís high speed 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.
WHY RESPONSE TIME MATTERS
Faster response time improves wideband feedback control, and can provide a safer, more powerful and accurate tune. AEMís Wideband Controllers with X-Digital technology can reduce deadtime and improve the performance of your vehicle through more accurate AFR tuning. Deadtime is the delay between when exhaust gas composition changes and when that change is reported by the O2 sensor. While flow of exhaust gases (transport delay) can affect deadtime, it is not the only source. Often, the sensing elements response to the gas is the largest contributor to deadtime when an engine is in high RPM under load.
When tuning an engine using wideband AFR feedback control on an inertia dyno, deadtime affects the data you are looking at because it is reported in a different operating location than when it actually occurred. This means with long deadtimes, whatever changes you make to the base fueling will likely be in the wrong location. This can be particularly dangerous to high compression and high-boost forced induction vehicles, and EFI systems that use feedback control to auto tune.
Reducing deadtime improves wideband feedback control, and can provide a safer, more powerful and accurate tune. AEMís Wideband Controllers with X-Series digital technology can reduce deadtime and improve the performance of your vehicle through more accurate AFR tuning.
FACTORY CALIBRATION RESISTOR OR FREE-AIR CAL, ITíS YOUR CHOICE!
The X-Series Wideband Gauge, X-Series Inline Controller, and PRO Dual Channel Wideband controller, support the popular Bosch LSU 4.9 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. Itís the perfect marriage of simplicity and accuracy!
WHAT IS A WIDEBAND UEGO AIR/FUEL CONTROLLER?
AEM's Wideband UEGO (Universal Exhaust Gas Oxygen, pronounced ďYou-Way-GoĒ) Controllers are powerful, cost effective tuning tools that allow users to accurately monitor the Air/Fuel Ratio (AFR) of their engine.
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.
CAN I CHANGE THE AEM UEGO SENSORíS CONNECTOR?
No. There is a laser-etched, calibrated resistor in the sensorís connector body. This resistor is specifically created for the exact sensor that it is attached to. Modifying this will invalidate the sensorís output.
** 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 vehicleís maintenance program. When performing free-air calibration, please follow the procedure outlined in the instruction manual.
