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.

Perfect for an English Bulldog 🐶
Size: 41.3 x 27.5, Color: Grey
Very good bed, super soft and comfortable. My English Bulldog loved it from day one and uses it all the time. The size is perfect and it doesn’t sink too much. The non-slip bottom keeps it in place.
It’s also easy to wash and comes out like new, which is a big plus.
100% recommended. 🐾

Great Product at an Amazing Price!
Size: 41.3 x 27.5, Color: Coffee
I bought 2 of these crate liners to use as beds when I board my dogs and I couldn't be more thrilled with them! These beds are much sturdier than I expected for the price, very thick and comfy and both of my dogs love theirs!
Even my 130lb Fila x Rottie is supported by this bed, and he's cushioned from the cement floors at the boarding facility enough I don't worry about any pressure sores on him.
I'll definitely be buying extras of these beds to have on hand.

Nice doggy beds for the fur-babies!
Size: 41.3 x 27.5, Color: Grey, Size: 41.3 x 27.5, Color: Grey
This is nice, soft and fluffy, the fur-babies seem to love it. It does shed a lot so far. Females have been fluffing it themselves (dig/scratching) and has seem to be holding up well. These arrived vacuumed sealed. I was a little worried there would be a strong scent but was pleasantly surprised they aired out very well. I think these will be a nice addition to my fur-babies kennel. I only wished I would have sized up one more for a better fit for my kennel that’s interiorly 53x45. I think these 47x35 instead of 41x27 would have fit better. Other than the shedding and (my fault) the sizing I think they are great. I think a removable cover would have been nice but these are priced right I could always just buy again if need be.
