Grams is proud to offer the most innovative Wideband Air/Fuel Ratio Gauge. Air/Fuel Ratio data is important for tuning as it helps achieve optimum power and safety. Unlike other gauges on the market Grams Wideband is fully digital and features large LED numbers for an easy read. The Wideband is compatible with all fuel types and uses Bosch Power LSU 4.9.Grams UEGO – wideband air fuel gauge utilizes the Bosch LSU 4.9 sensor which is superior to the LSU 4.2 sensors. One major difference between the LSU 4.9 and LSU 4.2 is the LSU 4.9 uses the reference pumping-current, while the LSU 4.2 uses the reference air. This allows the LSU 4.9 to get rid of the reference air, and therefore remove the biggest failure mode; as a result the LSU 4.9 has a long life and maintains accuracy throughout the life of the sensor.
Most aftermarket wideband controllers still use the LSU 4.2, mainly for low cost reasons. Bosch sells the LSU 4.2 to the aftermarket at a much lower price than the LSU 4.9, plus, many of the controllers are not able to adapt to the new LSU 4.9 as the technology is different. In fact, most all OEM who use Bosch sensors are using the LSU 4.9.
The Grams wideband air fuel gauges feature a 0-5v output for closed-loop feedback when pairing with a standalone ECU. Grams Wideband measures at 52mm with an LED display that features a 3 color sweep from Red, Yellow to Green. The Grams Wideband using the Bosch LSU 4.9 is able to have accuracy down to .001 and utilizes a 4 digit display.

Entertaining
Color: Blue
This smart ball is a great toy for your dog. It’s the perfect size for most dogs and it’s made of durable material that chewing doesn’t hurt. It’s easy to charge and will run for hours. It’s very quiet and has 3 modes of play to choose from, rolling, bouncing or a combination of both to keep them (and you) entertained for hours.

I bought this interactive ball for my dog, and it has been an excellent purchase. He loves playing with it because it moves and bounces on its own, keeping him entertained for a long time. It feels durable, is easy to charge, and is of very high quality. I would definitely recommend it to anyone looking for a fun, long-lasting toy for their pets.

Not Golden Retriever Proof
Color: Red
My Golden Retriever destroyed this ball within a couple hours of receiving it. Turned my back for a minute and she had it open and chewed on the internal part wrecking the charging port. Then proceeded to rip chunks off of the outer part. This is a great idea but maybe make it more difficult to open. BTW, my dog loved the ball when it was functioning properly.

Great Interactive Toy
Color: Blue
This toy is amazing for keeping my dog entertained and active! The movement feature really grabs my dog’s attention, and he loves chasing and playing with it. It is strong and durable, and the design is very cute.
It’s also great for preventing boredom, especially when my dog has extra energy. The battery lasts a good amount of time and it was very easy to set up. My dog plays with it every day and hasn’t gotten tired of it.
I highly recommend this toy to anyone who wants a fun and interactive way to keep their dog happy and busy!
