Aircraft Fuel System Operation

AEM’s X-Collection Wideband UEGO Air/Fuel Ratio Sensor Controller Gauges are built upon distinctive, patent-pending X-Digital technology that makes them the fastest responding wideband air/gas ratio controllers in impartial testing towards 17 different wideband UEGO air/gas controllers*.

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

The X-Collection Wideband UEGO AFR Gauge has a person configurable show via buttons on the gauge face that let you change AFR values for different fuels, Lambda or O2%, change the center show to three or four digits, perform a free-air calibration if desired as the sensor ages, and alter the CAN message ID when linking multiple X-Collection Inline Controllers or X-Collection Controller Gauges. A black bezel and black twin-faced faceplate for air/gas and Lambda are included, and an optional silver bezel with white twin-faced Aircraft Fuel System Operation and Lambda faceplate is available (PN 30-0300-ACC, sold separately). An Auto Dimming feature is included. Locking connectors guarantee a positive 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 feedback control and knowledge logging, and an AEMnet (CANbus) output for knowledge logging. AEMnet permits additional X-Collection Wideband Controllers to be daisy chained together (as much as sixteen cylinders) for recording AFR in multiple cylinders. It supports car/system voltages as much as 16V, and can be used on EFI or carbureted functions, and dynamometers in functions using gasoline, methanol, ethanol, Diesel, propane and CNG.

X-Digital Technology

X-Digital wideband technology gives these controllers the ability to learn and report values that different controllers do not, which may ship more optimized engine tuning and a safer total working condition. The controller’s high speed digital implementation ensures no lack of sign constancy and full transient response, making it able to establish the slightest fluctuations in AFR and output them in full value.

Why Does Response Time Matter?

Faster response time improves wideband feedback control, and can present a safer, more powerful and accurate tune. AEM’s Wideband Controllers with X-Digital technology can reduce deadtime and improve the efficiency of your car by way of more accurate AFR tuning. Deadtime is the delay between when exhaust gasoline composition changes and when that change is reported by the O2 sensor. Whereas circulate of exhaust gases (transport delay) can have an effect on deadtime, it isn't the one source. Typically, the sensing parts response to the gasoline is the most important contributor to deadtime when an engine is in high RPM beneath load.

When tuning an engine using wideband AFR feedback control on an inertia dyno, deadtime affects the info you are looking at as a result of it is reported in a different working location than when it really occurred. This means with lengthy deadtimes, no matter changes you make to the base fueling will probably be within the unsuitable location. This may be particularly dangerous to high compression and high-increase forced induction autos, and EFI programs that use feedback control to auto tune.

Reducing deadtime improves wideband feedback control, and can present a safer, more powerful and accurate tune. AEM’s Wideband Controllers with X-Collection digital technology can reduce deadtime and improve the efficiency of your car by way of more accurate AFR tuning.

Manufacturing facility Calibration Resistor or Free Air Output
The X-Collection Wideband Gauge and X-Collection Inline Controller help the popular Bosch 4.9LSU sensor and can make the most of both the manufacturing facility calibration resistor and free-air calibration methods**. This permits customers to benefit from the precise manufacturing facility resistor calibration when a sensor is new however then permits at no cost-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 (Common Exhaust Fuel Oxygen, pronounced “You-Means-Go”) Controllers are powerful, cost efficient tuning instruments that allow customers to accurately monitor the Air/Fuel Ratio (AFR) of their engine.

Why Use A Wideband??

Accurate AFR knowledge is vital when tuning an engine. Operating rich (very low air/gas ratio, excessive gas) could cause a loss in power, whereas working too lean (very high Aircraft Fuel System Operation ratio, not enough gas) might result in serious engine damage. Utilizing a wideband air/gas controller throughout the tuning process lets you monitor AFR and adjust tuning parameters to optimize them for max power and efficiency. AEM has a complete line of highly accurate, reliable wideband air/gas controllers that can help guarantee your car is optimally tuned.
