AEM's x-Series Inline Wideband UEGO Air/Fuel Ratio Controllers are built upon unique, patented, 100% digital technology that makes them the fastest responding wideband air/fuel ratio controllers in independent testing*. The x-Series Wideband UEGO Air/Fuel Ratio Controller replaces the popular 30-2310 Inline Controller.

x-Series Inline Wideband UEGO Controller features a weather-resistant, low-profile enclosure with status LEDs. It is ideal for users who do not need a gauge display and want the fastest response time when data logging or for feedback control when tuning with an engine management system.

The x-Series Inline Controller includes a 0-5v and RS232 Serial Port output for feedback control and data logging, and an AEMnet (CANbus) output for data logging and daisy chaining multiple x-Series Controllers 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.

Patented x-Digital wideband technology (Patent 9,575,030) 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 controller's 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.

Faster response time improves wideband feedback control, and can provide a safer, more powerful and accurate tune. AEM's Wideband Controllers with x-Series 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.

he x-Series Wideband Gauge and 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!

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.

Who is AEM?

AEM is an aftermarket company and was founded by John Concialdi and Bob Sullivan back in 1987. The company specializes in providing performance upgrade parts for various automobiles. 

It initially catered to vintage vehicles and modified imports used for street racing. By the early 1990s, it has already established itself as a top modifier and has been chosen by racers day in and day out. 

Today, AEM has remained at the forefront in the industry and has since provided the best air intake products in the market.

Racers Choice

The company rose to success because the cars fitted with their products won actual races. AEM has been a brand synonymous with fast cars and has been used by import racing legends such as Abel Ibarra, Adam Saruwatari, Tony Fuchs, and more.

The Tradition of Continuous Innovation

AEM has always been a pioneer in setting trends when it comes to aftermarket performance parts. They were the first to offer a packaged air induction system. This paved the way for the 'do-it-yourself' upgrade for most import vehicles. 

They also pioneered the design of intake tubes with specific tube lengths and diameter, and coined the phrase Cold Air Intake when they saw the advantage of having cooler air for the engine.

Some other innovations they did were the conical air filters with built-in air horns, dual-chambered intake kits, a unique bypass valve that prevents hydro locking, hybrid induction systems, and electronically tuned air intakes. 

This shows how AEM has always pushed the boundaries of air intake design in search of more horsepower.

Tried and Tested

All of AEM's products are tested by various independent and 3rd party companies and prove that their products produce the power they claimed, which helps them cement their status as industry leaders.
