Aircraft Fuel System Schematic

AEM’s X-Collection Wideband UEGO Air/Gasoline Ratio Sensor Controller Gauges are constructed upon unique, patent-pending X-Digital know-how that makes them the fastest responding wideband air/gasoline ratio controllers in impartial testing against 17 other wideband UEGO air/gasoline controllers*.

The X-Collection Wideband UEGO AFR Sensor Controller Gauge (PN 30-0300) measures 2 1/sixteenth-inch (52mm) in diameter, and encompasses a trendy, visually placing faceplate and new seven-segment heart display that is 87% bigger than the 30-4110 AEM Wideband Gauge’s heart display. This creates the perception of a bigger total gauge, however in a standard 52mm dimension for simple mounting. Its slim depth (lower than one inch total) and ultra slim cup depth of .200-inches dramatically increases its utility base and potential mounting locations.

The X-Collection Wideband UEGO AFR Gauge has a consumer configurable display through buttons on the gauge face that permit you to change AFR values for different fuels, Lambda or O2%, change the middle display to a few 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-Collection Inline Controllers or X-Collection Controller Gauges. A black bezel and black twin-faced faceplate for air/gasoline and Lambda are included, and an elective silver bezel with white twin-faced Aircraft Fuel System Schematic and Lambda faceplate is offered (PN 30-0300-ACC, sold individually). An Auto Dimming function is included. Locking connectors ensure a positive connection between the harnesses and gauge and a brand new single board design provides to the brand new gauge’s durability.

The gauge features a zero-5v and RS232 Serial Port output for suggestions control and knowledge logging, and an AEMnet (CANbus) output for knowledge logging. AEMnet allows extra X-Collection Wideband Controllers to be daisy chained collectively (up to 16 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 using gasoline, methanol, ethanol, Diesel, propane and CNG.

X-Digital Technology

X-Digital wideband know-how provides these controllers the flexibility to read and report values that other controllers do not, which can deliver more optimized engine tuning and a safer total operating condition. The controller’s high velocity digital implementation ensures no loss of sign fidelity 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 suggestions control, and might present a safer, more highly effective and correct tune. AEM’s Wideband Controllers with X-Digital know-how can scale back deadtime and enhance the performance of your automobile by more correct AFR tuning. Deadtime is the delay between when exhaust gas composition changes and when that change is reported by the O2 sensor. While circulation of exhaust gases (transport delay) can have an effect on deadtime, it is not the one source. Usually, the sensing components response to the gas is the largest contributor to deadtime when an engine is in high RPM under load.

When tuning an engine using wideband AFR suggestions control on an inertia dyno, deadtime impacts the data you're looking at because it's reported in a special operating location than when it really occurred. This implies with long deadtimes, no matter changes you make to the bottom fueling will possible be in the mistaken location. This can be notably dangerous to high compression and high-enhance pressured induction automobiles, and EFI methods that use suggestions control to auto tune.

Lowering deadtime improves wideband suggestions control, and might present a safer, more highly effective and correct tune. AEM’s Wideband Controllers with X-Collection digital know-how can scale back deadtime and enhance the performance of your automobile by more correct AFR tuning.

Factory Calibration Resistor or Free Air Output
The X-Collection Wideband Gauge and X-Collection Inline Controller support the popular Bosch 4.9LSU sensor and might make the most of both the manufacturing facility calibration resistor and free-air calibration strategies**. This permits customers to make the most of the exact manufacturing facility resistor calibration when a sensor is new however then allows without cost-air calibrations if the consumer desires 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-Manner-Go”) Controllers are highly effective, price efficient tuning tools that permit customers to accurately monitor the Air/Gasoline Ratio (AFR) of their engine.

Why Use A Wideband??

Accurate AFR knowledge is crucial when tuning an engine. Working wealthy (very low air/gasoline ratio, excessive gasoline) can cause a loss in energy, whereas working too lean (very high Aircraft Fuel System Schematic ratio, not sufficient gasoline) might lead to serious engine damage. Utilizing a wideband air/gasoline controller during the tuning course of allows you to monitor AFR and modify tuning parameters to optimize them for maximum energy and efficiency. AEM has a comprehensive line of extremely correct, dependable wideband air/gasoline controllers that may assist ensure your automobile is optimally tuned.
