Wideband Air Fuel Gauge Sensor

Wideband Air Fuel Gauge Sensor

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 quickest responding wideband air/gas ratio controllers in unbiased testing in opposition to 17 other wideband UEGO air/gas controllers*.

The X-Collection Wideband UEGO AFR Sensor Controller Gauge (PN 30-0300) measures 2 1/sixteenth-inch (52mm) in diameter, and contains a modern, visually putting faceplate and new seven-segment heart show that's 87% larger than the 30-4110 AEM Wideband Gauge’s heart display. This creates the perception of a larger total gauge, however in a standard 52mm size for straightforward mounting. Its slim depth (less than one inch total) and ultra slim cup depth of .200-inches dramatically will increase its application base and potential mounting locations.

The X-Collection Wideband UEGO AFR Gauge has a user configurable show via buttons on the gauge face that will let you change AFR values for various fuels, Lambda or O2%, change the middle show to a few or four digits, perform a free-air calibration if desired as the sensor ages, and change the CAN message ID when linking multiple X-Collection Inline Controllers or X-Collection Controller Gauges. A black bezel and black twin-confronted faceplate for air/gas and Lambda are included, and an optional silver bezel with white twin-confronted Wideband Air Fuel Gauge Sensor and Lambda faceplate is offered (PN 30-0300-ACC, bought individually). An Auto Dimming characteristic is included. Locking connectors ensure a optimistic connection between the harnesses and gauge and a brand 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 information logging, and an AEMnet (CANbus) output for information logging. AEMnet allows extra X-Collection Wideband Controllers to be daisy chained collectively (up to sixteen cylinders) for recording AFR in multiple cylinders. It helps automobile/system voltages up to 16V, and can be utilized on EFI or carbureted applications, and dynamometers in applications utilizing gasoline, methanol, ethanol, Diesel, propane and CNG.

X-Digital Technology

X-Digital wideband technology gives these controllers the ability to read and report values that other controllers don't, which can deliver extra optimized engine tuning and a safer total operating condition. The controller’s high speed digital implementation ensures no lack of sign constancy and full transient response, making it able to identify the slightest fluctuations in AFR and output them in full value.

Why Does Response Time Matter?

Sooner response time improves wideband suggestions management, and can provide a safer, extra powerful and accurate tune. AEM’s Wideband Controllers with X-Digital technology can reduce deadtime and improve the efficiency of your automobile via extra accurate AFR tuning. Deadtime is the delay between when exhaust fuel composition changes and when that change is reported by the O2 sensor. Whereas move of exhaust gases (transport delay) can have an effect on deadtime, it's not the only source. Often, the sensing components response to the fuel is the largest contributor to deadtime when an engine is in high RPM under load.

When tuning an engine utilizing wideband AFR suggestions management on an inertia dyno, deadtime impacts the data you're looking at because it's reported in a special operating location than when it truly occurred. This implies with lengthy deadtimes, whatever changes you make to the bottom fueling will doubtless be in the mistaken location. This can be notably dangerous to high compression and high-boost compelled induction autos, and EFI programs that use suggestions management to auto tune.

Lowering deadtime improves wideband suggestions management, and can provide a safer, extra powerful and accurate tune. AEM’s Wideband Controllers with X-Collection digital technology can reduce deadtime and improve the efficiency of your automobile via extra accurate AFR tuning.

Manufacturing unit 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 utilize both the manufacturing facility calibration resistor and free-air calibration methods**. This allows users to make the most of the precise manufacturing facility resistor calibration when a sensor is new however then allows totally free-air calibrations if the user wishes when the sensor ages. It’s the right marriage of simplicity and accuracy!

What Is A Wideband??

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

Why Use A Wideband??

Correct AFR information is important when tuning an engine. Running wealthy (very low air/gas ratio, excessive gas) could cause a loss in power, while operating too lean (very high Wideband Air Fuel Gauge Sensor ratio, not enough gas) may result in serious engine damage. Using a wideband air/gas controller during the tuning process allows you to monitor AFR and regulate tuning parameters to optimize them for max power and efficiency. AEM has a comprehensive line of highly accurate, reliable wideband air/gas controllers that may help ensure your automobile is optimally tuned.
