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.

Terrifying jaw strength..
Color: Green, Size: Medium(30-55 lbs)
Have 2 Corgi and it scares me that they make this thing squeak. The bite pressure they have now from working out jaw to squeak this like it's nothing. Didn't expect our smaller corgi to be able to squeak this couldn't at first now she just goes ham on it like it's no big deal.

Very sturdy for an aggressive chewer
Color: Green, Size: Large(50-90 lbs)
I was so surprised that this has lasted so long for my Black lab, who is an aggressive chewer. It is his all-time favorite toy. He chews it many times every day and the squeaker still works!

I FINALLY GOT AN INDESTRUCTIBLE TOY!!! Yes!
Color: Green, Size: Large(50-90 lbs), Color: Green, Size: Large(50-90 lbs)
This one is TRULY indestructible! I’ve been purchasing one after another trying to find something that she cannot break in 5 mins. Everything I’ve ordered (until this one) has been SHREDDED in 3-10 minutes!
It’s TRUE RUBBER! I’m so happy with my purchase!
See the picture below- we’ve had it for a couple months now and she has barely chewed off just a few small nubs! Which she’s proud of 😆
If you truly want a challenge for your CRAZY DOG- you will love this squeaker!

Rough and tough chew toy
Color: Azure, Size: Large(50-90 lbs)
This is a thick and heavy duty toy to stand up to medium to large dogs who are heavy chewers. And the rough textures really encourages my dog and it is the perfect size to throw and play fetch. Very sturdy…I bought around Christmas and it’s almost may and she hasn’t destroyed it yet!!!

Very sturdy and strong toy
Color: Green, Size: Large(50-90 lbs)
This keeps my dog busy. He has a blast with it. It is a little bit big for his mouth, but he still seems to have fun with it. My dog is German Shepherd and Australian Shepherd.
