Best Wideband Air Fuel Gauge

Best Wideband Air Fuel Gauge

AEM’s X-Collection Wideband UEGO Air/Gas 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 impartial testing against 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 contains a fashionable, visually putting faceplate and new seven-section heart display that is 87% larger than the 30-4110 AEM Wideband Gauge’s heart display. This creates the notion of a bigger general gauge, however in a standard 52mm size for simple mounting. Its slim depth (lower than one inch general) 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 consumer configurable display through buttons on the gauge face that assist you to change AFR values for various fuels, Lambda or O2%, change the middle display to 3 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-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 non-obligatory silver bezel with white twin-faced Best Wideband Air Fuel Gauge and Lambda faceplate is accessible (PN 30-0300-ACC, sold individually). An Auto Dimming feature is included. Locking connectors guarantee a constructive connection between the harnesses and gauge and a new single board design adds to the new gauge’s durability.

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

X-Digital Technology

X-Digital wideband technology gives these controllers the flexibility to learn and report values that different controllers do not, which might ship extra optimized engine tuning and a safer general working condition. The controller’s high pace digital implementation ensures no lack 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?

Quicker response time improves wideband suggestions management, and can provide a safer, extra powerful and correct tune. AEM’s Wideband Controllers with X-Digital technology can cut back deadtime and enhance the efficiency of your automobile by way of extra correct AFR tuning. Deadtime is the delay between when exhaust fuel composition modifications and when that change is reported by the O2 sensor. While move of exhaust gases (transport delay) can affect deadtime, it is not the only source. Typically, the sensing elements response to the fuel is the biggest contributor to deadtime when an engine is in high RPM below load.

When tuning an engine utilizing wideband AFR suggestions management on an inertia dyno, deadtime impacts the information you are looking at because it is reported in a different working location than when it truly occurred. This implies with lengthy deadtimes, no matter modifications you make to the base fueling will possible be in the flawed location. This may be notably harmful to high compression and high-enhance compelled induction autos, and EFI methods that use suggestions management to auto tune.

Decreasing deadtime improves wideband suggestions management, and can provide a safer, extra powerful and correct tune. AEM’s Wideband Controllers with X-Collection digital technology can cut back deadtime and enhance the efficiency of your automobile by way of extra correct 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 each the manufacturing unit calibration resistor and free-air calibration methods**. This permits customers to reap the benefits of the precise manufacturing unit resistor calibration when a sensor is new however then allows for free-air calibrations if the consumer wishes when the sensor ages. It’s the proper 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 effective tuning instruments that allow customers to precisely monitor the Air/Gas Ratio (AFR) of their engine.

Why Use A Wideband??

Accurate AFR data is important when tuning an engine. Running rich (very low air/gas ratio, excessive gas) may cause a loss in power, while running too lean (very high Best Wideband Air Fuel Gauge ratio, not enough gas) may end in critical engine damage. Utilizing a wideband air/gas controller through the tuning course of means that you can monitor AFR and regulate tuning parameters to optimize them for optimum power and efficiency. AEM has a comprehensive line of extremely correct, reliable wideband air/gas controllers that can assist guarantee your automobile is optimally tuned.
