AEM’s X-Series Wideband UEGO Air/Fuel Ratio Sensor Controller Gauges are built upon distinctive, patent-pending X-Digital expertise that makes them the quickest responding wideband air/gasoline ratio controllers in independent testing against 17 different wideband UEGO air/gasoline controllers*.

The X-Series Wideband UEGO AFR Sensor Controller Gauge (PN 30-0300) measures 2 1/16th-inch (52mm) in diameter, and incorporates a modern, visually striking faceplate and new seven-phase middle show that is 87% larger than the 30-4110 AEM Wideband Gauge’s middle display. This creates the notion of a bigger total gauge, however in a typical 52mm dimension for easy mounting. Its slim depth (lower than one inch total) and extremely slim cup depth of .200-inches dramatically will increase its utility base and potential mounting locations.

The X-Series Wideband UEGO AFR Gauge has a person configurable show through buttons on the gauge face that permit you to change AFR values for various fuels, Lambda or O2%, change the center show to a few or 4 digits, carry out a free-air calibration if desired as the sensor ages, and alter the CAN message ID when linking a number of X-Series Inline Controllers or X-Series Controller Gauges. A black bezel and black dual-confronted faceplate for air/gasoline and Lambda are included, and an elective silver bezel with white dual-confronted Aircraft Fuel Systems Air Force and Lambda faceplate is obtainable (PN 30-0300-ACC, sold separately). An Auto Dimming feature is included. Locking connectors ensure a optimistic connection between the harnesses and gauge and a new single board design provides to the new gauge’s durability.

The gauge includes a zero-5v and RS232 Serial Port output for suggestions management and information logging, and an AEMnet (CANbus) output for information logging. AEMnet permits further X-Series Wideband Controllers to be daisy chained together (up to sixteen cylinders) for recording AFR in a number of cylinders. It supports car/system voltages up to 16V, and can be utilized on EFI or carbureted functions, and dynamometers in functions using gasoline, methanol, ethanol, Diesel, propane and CNG.

X-Digital Technology

X-Digital wideband expertise gives these controllers the flexibility to read and report values that different controllers do not, which may deliver more optimized engine tuning and a safer total working condition. The controller’s high speed digital implementation ensures no lack of signal constancy and full transient response, making it capable of identify the slightest fluctuations in AFR and output them in full value.

Why Does Response Time Matter?

Quicker response time improves wideband suggestions management, and might present a safer, more highly effective and correct tune. AEM’s Wideband Controllers with X-Digital expertise can scale back deadtime and improve the efficiency of your car via more correct AFR tuning. Deadtime is the delay between when exhaust gas composition modifications and when that change is reported by the O2 sensor. Whereas movement of exhaust gases (transport delay) can have an effect on deadtime, it is not the one source. Usually, the sensing components response to the gas is the most important contributor to deadtime when an engine is in high RPM underneath load.

When tuning an engine using wideband AFR suggestions management on an inertia dyno, deadtime impacts the data you are looking at as a result of it's reported in a distinct working location than when it really occurred. This means with lengthy deadtimes, no matter modifications you make to the base fueling will seemingly be in the improper location. This can be significantly dangerous to high compression and high-enhance compelled induction vehicles, and EFI systems that use suggestions management to auto tune.

Reducing deadtime improves wideband suggestions management, and might present a safer, more highly effective and correct tune. AEM’s Wideband Controllers with X-Series digital expertise can scale back deadtime and improve the efficiency of your car via more correct AFR tuning.

Manufacturing facility Calibration Resistor or Free Air Output
The X-Series Wideband Gauge and X-Series Inline Controller assist the favored Bosch 4.9LSU sensor and might utilize both the manufacturing facility calibration resistor and free-air calibration strategies**. This enables customers to take advantage of the precise manufacturing facility resistor calibration when a sensor is new however then permits free of charge-air calibrations if the person needs when the sensor ages. It’s the perfect marriage of simplicity and accuracy!

What Is A Wideband??

AEM's Wideband UEGO (Universal Exhaust Fuel Oxygen, pronounced “You-Method-Go”) Controllers are highly effective, price efficient tuning tools that enable customers to accurately monitor the Air/Fuel Ratio (AFR) of their engine.

Why Use A Wideband??

Accurate AFR information is crucial when tuning an engine. Running wealthy (very low air/gasoline ratio, excessive gasoline) could cause a loss in energy, while operating too lean (very high Aircraft Fuel Systems Air Force ratio, not sufficient gasoline) could lead to severe engine damage. Using a wideband air/gasoline controller through the tuning process means that you can monitor AFR and adjust tuning parameters to optimize them for optimum energy and efficiency. AEM has a complete line of extremely correct, reliable wideband air/gasoline controllers that may assist ensure your car is optimally tuned.
