AEM X-Series Inline Wideband UEGO AFR Sensor Controller with X-Digital Technology. Includes: X-Series Inline Wideband Controller, Bosch LSU 4.9 Sensor & O2 Sensor Bung

AEM’s X-Series Inline Wideband UEGO Air/Fuel Ratio Controllers are built upon unique, patented, 100% digital technology that makes them the fastest responding wideband air/fuel ratio controllers in independent testing*. The X-Series Wideband UEGO Air/Fuel Ratio Controller replaces the popular 30-2310 Inline Controller.

X-Series Inline Wideband UEGO Controller features a weather-resistant, low-profile enclosure with status LEDs. It is ideal for users who do not need a gauge display and want the fastest response time when data logging or for feedback control when tuning with an engine management system.

The X-Series Inline Controller includes a 0-5v and RS232 Serial Port output for feedback control and data logging, and an AEMnet (CANbus) output for data logging and daisy chaining multiple X-Series Controllers together (up to 16 cylinders) for recording AFR in multiple cylinders. It 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.

PATENTED X-DIGITAL TECHNOLOGY
Patented X-Digital wideband technology (Patent 9,575,030) gives these controllers the ability to read and report values that other controllers do not, which can deliver more optimized engine tuning and a safer overall operating condition. The controller’s high speed digital implementation ensures no loss of signal fidelity and full transient response, making it able to identify the slightest fluctuations in AFR and output them in full value.

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-Series 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 gases (transport delay) can affect deadtime, it is not the only source. Often, the sensing elements 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 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!

My pup absolutely loves it and it's helping him with teething. It doesn't break off in a bunch of big pieces, just tiny pieces. He spits out the little pieces thankfully! Very well made and smells appetizing to dogs! It definitely helps clean his teeth & the rest of his mouth!

My little Meg loves these chew bones, she sneaks in and steals them from our Golden Retriever and our Great Pyrenees. She chews the orange covering off in minutes and the under bone lasts a few weeks. The dogs steal them from each other all the time, even though I buy them each one. Highly recommend if you have a super chewer, just be mindful the orange cover is easily chewed off.

But It
Flavor Name: Peanut Butter, Size: Medium
My fur baby has his fair share of toys, but something about this one he won’t put down. Pieces fall off the ends once they chew on it for a while.
