Wideband Air Fuel Gauge Install

Wideband Air Fuel Gauge Install

AEM’s X-Collection Wideband UEGO Air/Fuel Ratio Sensor Controller Gauges are constructed upon distinctive, patent-pending X-Digital know-how that makes them the fastest 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 includes a modern, visually hanging faceplate and new seven-segment center display that is 87% bigger than the 30-4110 AEM Wideband Gauge’s center display. This creates the perception of a bigger overall gauge, but in a common 52mm measurement for easy mounting. Its slim depth (less than one inch overall) and extremely slim cup depth of .200-inches dramatically increases its software base and potential mounting locations.

The X-Collection Wideband UEGO AFR Gauge has a user configurable display by way of buttons on the gauge face that assist you to change AFR values for different fuels, Lambda or O2%, change the center display to 3 or 4 digits, carry out a free-air calibration if desired because 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 dual-faced faceplate for air/gas and Lambda are included, and an optionally available silver bezel with white dual-faced Wideband Air Fuel Gauge Install and Lambda faceplate is accessible (PN 30-0300-ACC, bought separately). An Auto Dimming function is included. Locking connectors guarantee a optimistic connection between the harnesses and gauge and a brand new single board design adds to the brand new gauge’s durability.

The gauge features a zero-5v and RS232 Serial Port output for suggestions management and knowledge logging, and an AEMnet (CANbus) output for knowledge logging. AEMnet allows extra X-Collection Wideband Controllers to be daisy chained together (up to sixteen cylinders) for recording AFR in multiple cylinders. It helps automobile/system voltages up to 16V, and can be used on EFI or carbureted purposes, and dynamometers in purposes using gasoline, methanol, ethanol, Diesel, propane and CNG.

X-Digital Technology

X-Digital wideband know-how gives these controllers the ability to read and report values that other controllers don't, which might deliver extra optimized engine tuning and a safer overall working condition. The controller’s high pace digital implementation ensures no loss of sign 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 accurate tune. AEM’s Wideband Controllers with X-Digital know-how can cut back deadtime and enhance the efficiency of your automobile through extra accurate AFR tuning. Deadtime is the delay between when exhaust gasoline composition adjustments and when that change is reported by the O2 sensor. While circulate of exhaust gases (transport delay) can have an effect on deadtime, it is not the only source. Often, the sensing elements response to the gasoline is the biggest contributor to deadtime when an engine is in high RPM beneath load.

When tuning an engine using wideband AFR suggestions management on an inertia dyno, deadtime impacts the data you're looking at as a result of it's reported in a special working location than when it really occurred. This means with long deadtimes, whatever adjustments you make to the bottom fueling will likely be in the fallacious location. This may be particularly harmful to high compression and high-enhance forced induction autos, and EFI systems that use suggestions management to auto tune.

Lowering deadtime improves wideband suggestions management, and may present a safer, extra highly effective and accurate tune. AEM’s Wideband Controllers with X-Collection digital know-how can cut back deadtime and enhance the efficiency of your automobile through extra accurate AFR tuning.

Manufacturing facility Calibration Resistor or Free Air Output
The X-Collection Wideband Gauge and X-Collection Inline Controller help the favored Bosch 4.9LSU sensor and may utilize each the manufacturing facility calibration resistor and free-air calibration methods**. This allows users to benefit from the precise manufacturing facility resistor calibration when a sensor is new but then allows totally free-air calibrations if the user desires when the sensor ages. It’s the right marriage of simplicity and accuracy!

What Is A Wideband??

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

Why Use A Wideband??

Accurate AFR knowledge is crucial when tuning an engine. Running rich (very low air/gas ratio, extreme gas) can cause a loss in energy, whereas working too lean (very high Wideband Air Fuel Gauge Install ratio, not sufficient gas) could lead to severe engine damage. Using a wideband air/gas controller through the tuning process permits you to monitor AFR and alter tuning parameters to optimize them for max energy and efficiency. AEM has a comprehensive line of highly accurate, reliable wideband air/gas controllers that may assist guarantee your automobile is optimally tuned.
