Innovate Air Fuel Ratio Gauge Kit

Innovate Air Fuel Ratio Gauge Kit

AEM’s X-Series Wideband UEGO Air/Gasoline Ratio Sensor Controller Gauges are constructed upon distinctive, patent-pending X-Digital know-how that makes them the quickest responding wideband air/fuel ratio controllers in impartial testing in opposition to 17 other wideband UEGO air/fuel controllers*.

The X-Series Wideband UEGO AFR Sensor Controller Gauge (PN 30-0300) measures 2 1/sixteenth-inch (52mm) in diameter, and features a fashionable, visually placing faceplate and new seven-phase heart show that's 87% larger than the 30-4110 AEM Wideband Gauge’s heart display. This creates the notion of a larger general gauge, however in a standard 52mm dimension for straightforward mounting. Its slim depth (lower than one inch general) and ultra slim cup depth of .200-inches dramatically will increase its utility base and potential mounting locations.

The X-Series Wideband UEGO AFR Gauge has a user configurable show via buttons on the gauge face that allow you to change AFR values for different fuels, Lambda or O2%, change the center show to 3 or four digits, carry out a free-air calibration if desired as the sensor ages, and alter the CAN message ID when linking multiple X-Series Inline Controllers or X-Series Controller Gauges. A black bezel and black twin-confronted faceplate for air/fuel and Lambda are included, and an optionally available silver bezel with white twin-confronted Innovate Air Fuel Ratio Gauge Kit and Lambda faceplate is obtainable (PN 30-0300-ACC, bought individually). An Auto Dimming characteristic is included. Locking connectors guarantee a constructive connection between the harnesses and gauge and a new single board design provides to the brand new gauge’s durability.

The gauge features a zero-5v and RS232 Serial Port output for feedback management and information logging, and an AEMnet (CANbus) output for information logging. AEMnet allows extra X-Series Wideband Controllers to be daisy chained collectively (as much as 16 cylinders) for recording AFR in multiple cylinders. It supports vehicle/system voltages as much as 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 know-how offers these controllers the ability to read and report values that other controllers do not, which can ship extra optimized engine tuning and a safer general working condition. The controller’s excessive 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?

Faster response time improves wideband feedback management, and might present a safer, extra highly effective and correct tune. AEM’s Wideband Controllers with X-Digital know-how can scale back deadtime and enhance the performance of your vehicle via extra correct AFR tuning. Deadtime is the delay between when exhaust fuel composition adjustments and when that change is reported by the O2 sensor. Whereas movement of exhaust gases (transport delay) can affect deadtime, it isn't the one source. Typically, the sensing components response to the fuel is the biggest contributor to deadtime when an engine is in excessive RPM underneath load.

When tuning an engine utilizing wideband AFR feedback management on an inertia dyno, deadtime impacts the data you are looking at as a result of it's reported in a special working location than when it actually occurred. This implies with long deadtimes, whatever adjustments you make to the base fueling will seemingly be in the flawed location. This may be significantly harmful to excessive compression and excessive-boost pressured induction autos, and EFI methods that use feedback management to auto tune.

Lowering deadtime improves wideband feedback management, and might present a safer, extra highly effective and correct tune. AEM’s Wideband Controllers with X-Series digital know-how can scale back deadtime and enhance the performance of your vehicle via extra correct AFR tuning.

Manufacturing unit Calibration Resistor or Free Air Output
The X-Series Wideband Gauge and X-Series Inline Controller help the popular Bosch 4.9LSU sensor and might make the most of each the factory calibration resistor and free-air calibration strategies**. This enables customers to take advantage of the precise factory resistor calibration when a sensor is new however then allows free of charge-air calibrations if the user needs when the sensor ages. It’s the perfect marriage of simplicity and accuracy!

What Is A Wideband??

AEM's Wideband UEGO (Common Exhaust Gas Oxygen, pronounced “You-Approach-Go”) Controllers are highly effective, cost efficient tuning tools that enable customers to accurately monitor the Air/Gasoline Ratio (AFR) of their engine.

Why Use A Wideband??

Accurate AFR information is important when tuning an engine. Running rich (very low air/fuel ratio, excessive fuel) could cause a loss in energy, whereas running too lean (very excessive Innovate Air Fuel Ratio Gauge Kit ratio, not enough fuel) could result in critical engine damage. Using a wideband air/fuel controller through the tuning course of permits you to monitor AFR and alter tuning parameters to optimize them for max energy and efficiency. AEM has a comprehensive line of extremely correct, reliable wideband air/fuel controllers that may help guarantee your vehicle is optimally tuned.
