AEM 30-0300 FITS: X-Series Wideband UEGO AFR Sensor Controller Gauge GaugesFaster 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 gases can affect deadtime, it is not the only

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 gases 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 tuning an engine using wideband AFR feedback control, deadtime affects the data you are looking at because it is reported in a different operating location than when it occurred. This means whatever changes you make to the base fueling will likely be in the wrong timeframe. This can be particularly dangerous to high cylinder pressure applications, and EFI systems that use feedback control.

These are cheaply made, and garbage, highly dangerous letting a dog chew on a battery pack
Color: Grid Pattern
These units are garbage. I got one for each of my dogs charged it up turned it on put it inside the rubberized ball shell and securely fastened it less than two minutes later my dog had taken it apart by just biting it and then started to chew on the battery and motor unit. So if you wanna have a lithium polymer fire in your house and potentially kill your animal, go ahead and get this, but if you do not want a fire in your house and you want your animal to live then absolutely do not buy this garbage it’s cheap we made and it’s not strong enough for any dog

Good Product, but images over promise just a little.
Color: Ripple Pattern
- Performs well on tile and low pile carpet. On artificial grass it doesn’t roll even on the highest setting; it only vibrates. Watch the video. - Still fun for my pup. I’ve only had it a day so no clue about durability although my dog is a strong chewer. - Price Value: When purchased it was 2 balls for the same price of a single ball from competitor. - Material feels like a Nerf football. Easy to disassemble and charge.

Best jiggle balls we have found thus far
Color: Ripple Pattern
Yes ! First off this was a great value for the money. The balls function just as described and they have a decent battery life. They entertain both our goldens for a good bit of time. They have so far held up and not been chewed up . We limit the time and put them away after that time.. to avoid them being destroyed. Of all the jiggle balls we have purchased these are by far the best. The way the component is encased in the rubber protects it.. and it screws together very well. I am so pleased with these !
