AEM’s X-Collection Wideband UEGO Air/Gasoline Ratio Sensor Controller Gauges are constructed upon distinctive, patent-pending X-Digital technology that makes them the fastest responding wideband air/gasoline ratio controllers in independent testing against 17 other wideband UEGO air/gasoline controllers*.

The X-Collection Wideband UEGO AFR Sensor Controller Gauge (PN 30-0300) measures 2 1/16th-inch (52mm) in diameter, and contains a fashionable, visually hanging faceplate and new seven-section middle display that's 87% larger than the 30-4110 AEM Wideband Gauge’s middle display. This creates the notion of a larger overall gauge, but in a typical 52mm dimension for easy mounting. Its slim depth (less than one inch overall) and extremely slim cup depth of .200-inches dramatically increases its utility base and potential mounting locations.

The X-Collection Wideband UEGO AFR Gauge has a person configurable display by way of buttons on the gauge face that allow you to change AFR values for different fuels, Lambda or O2%, change the middle display to three or 4 digits, perform a free-air calibration if desired as the sensor ages, and alter the CAN message ID when linking a number of X-Collection Inline Controllers or X-Collection Controller Gauges. A black bezel and black twin-faced faceplate for air/gasoline and Lambda are included, and an non-obligatory silver bezel with white twin-faced Aircraft Fuel System Diagram and Lambda faceplate is obtainable (PN 30-0300-ACC, offered individually). An Auto Dimming feature is included. Locking connectors guarantee a optimistic connection between the harnesses and gauge and a new single board design adds to the new gauge’s durability.

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

X-Digital Technology

X-Digital wideband technology gives these controllers the flexibility to read and report values that other controllers don't, which may deliver extra optimized engine tuning and a safer overall operating condition. The controller’s high velocity digital implementation ensures no loss of signal fidelity and full transient response, making it capable of establish the slightest fluctuations in AFR and output them in full value.

Why Does Response Time Matter?

Sooner response time improves wideband suggestions management, and may present a safer, extra highly effective and correct tune. AEM’s Wideband Controllers with X-Digital technology can cut back deadtime and improve the efficiency of your car by extra correct AFR tuning. Deadtime is the delay between when exhaust gas composition modifications and when that change is reported by the O2 sensor. Whereas flow of exhaust gases (transport delay) can have an effect on deadtime, it is not the only source. Usually, the sensing parts response to the gas is the largest contributor to deadtime when an engine is in high RPM beneath load.

When tuning an engine utilizing wideband AFR suggestions management on an inertia dyno, deadtime impacts the information you are looking at because it's reported in a special operating location than when it actually occurred. This implies with lengthy deadtimes, no matter modifications you make to the bottom fueling will seemingly be within the incorrect location. This can be notably dangerous to high compression and high-increase pressured induction vehicles, and EFI techniques that use suggestions management to auto tune.

Lowering deadtime improves wideband suggestions management, and may present a safer, extra highly effective and correct tune. AEM’s Wideband Controllers with X-Collection digital technology can cut back deadtime and improve the efficiency of your car by extra correct AFR tuning.

Factory Calibration Resistor or Free Air Output
The X-Collection Wideband Gauge and X-Collection Inline Controller support the favored Bosch 4.9LSU sensor and may make the most of each the factory calibration resistor and free-air calibration strategies**. This permits users to make the most of the precise factory resistor calibration when a sensor is new but then allows totally free-air calibrations if the person wishes when the sensor ages. It’s the right marriage of simplicity and accuracy!

What Is A Wideband??

AEM's Wideband UEGO (Universal Exhaust Fuel Oxygen, pronounced “You-Means-Go”) Controllers are highly effective, value efficient tuning instruments that allow users to precisely monitor the Air/Gasoline Ratio (AFR) of their engine.

Why Use A Wideband??

Correct AFR data is crucial when tuning an engine. Running rich (very low air/gasoline ratio, excessive gasoline) could cause a loss in power, while working too lean (very high Aircraft Fuel System Diagram ratio, not enough gasoline) might end in serious engine damage. Utilizing a wideband air/gasoline controller during the tuning process permits you to monitor AFR and regulate tuning parameters to optimize them for maximum power and efficiency. AEM has a comprehensive line of extremely correct, dependable wideband air/gasoline controllers that may help guarantee your car is optimally tuned.
