AEM’s X-Series Wideband UEGO Air/Fuel Ratio Sensor Controller Gauges are built on patented, 100% Digital technology (Patent 9,575,030) that makes them the fastest responding wideband air/fuel ratio controllers in independent testing.*
The X-Series Wideband UEGO AFR Gauge has a user-configurable display via buttons on the gauge face that allows you to change AFR values for different fuels, Lambda or O2%, change the center display to three or four digits, perform a free-air calibration if desired as the sensor ages, and change the CAN message ID when linking multiple X-Series Inline Controllers or X-Series Controller Gauges.
- Measures 2 1/16th-inches (52mm) in diameter and features a seven-segment center display in a common 52mm size for easy mounting.
- Slim depth (less than one inch overall) and ultra-slim cup depth of .200-inches dramatically increases application base and potential mounting locations.
- Includes black bezel and black dual-faced faceplate for air/fuel and Lambda as well as Auto-Dimming feature.
- Locking connectors ensure a positive connection between the harnesses and gauge and a new single board design adds to the new gauge’s durability.
- Gauge includes a 0-5v and RS232 Serial Port output for feedback control and data logging, and an AEMnet (CANbus) output for data logging.
- AEMnet allows additional X-Series Wideband Controllers to be daisy chained together (up to 16 cylinders) for recording AFR in multiple cylinders.
- Supports vehicle/system voltages up to 16V, and can be used on EFI or carbureted applications, and dynamometers in applications using gasoline, methanol, ethanol, Diesel, propane, and CNG.
WHY RESPONSE TIME MATTERS
Faster response time improves wideband feedback control, and can provide a safer, more powerful and accurate tune. AEM’s Wideband Controllers with X-Digital technology can reduce deadtime and improve the performance of your vehicle through more accurate AFR tuning.
Deadtime is the delay between when exhaust gas composition changes and when that change is reported by the O2 sensor. While flow of exhaust gasses (transport delay) can affect deadtime, it is not the only source. Often, the sensing element's response to the gas is the largest contributor to deadtime when an engine is at high RPM under load.
When tuning an engine using wideband AFR feedback control on an inertia dyno, deadtime affects the data you are looking at because it is reported in a different operating location than when it actually occurred. This means with long deadtimes, whatever changes you make to the base fueling will likely be in the wrong location. This can be particularly dangerous to high compression and high-boost forced induction vehicles, and EFI systems that use feedback control to auto-tune.
Reducing deadtime improves wideband feedback control, and can provide a safer, more powerful and accurate tune. AEM’s Wideband Controllers with X-Series digital technology can reduce deadtime and improve the performance of your vehicle through more accurate AFR tuning.
FACTORY CALIBRATION RESISTOR OR FREE-AIR CAL, IT’S YOUR CHOICE.
The X-Series Wideband Gauge and X-Series Inline Controller support the popular Bosch 4.9LSU sensor and can utilize both the factory calibration resistor and free-air calibration methods**. This allows users to take advantage of the precise factory resistor calibration when a sensor is new but then allows for free-air calibrations if the user desires when the sensor ages. It’s the perfect marriage of simplicity and accuracy!
* Independently tested at 360° Product Testing (results reported on August 31st, 2015) against 17 competitors wideband UEGO Air/Fuel Controllers. AEM X-Series Inline with Bosch 4.9LSU wideband sensor and AEM X-Series Wideband UEGO AFR Gauge with Bosch 4.9LSU sensor recorded the fastest response times.
** Wideband UEGO sensors are wear items and their lifespan is determined by many factors including contamination from leaded fuels, automotive fluids, particulates, mechanical or thermal shock and from being unheated and exposed to the exhaust stream. Free-air calibration may correct drift as a sensor ages, but it is recommended that they are replaced as part of your vehicle’s maintenance program. When performing free-air calibration, please follow the procedure outlined in the instruction manual.
