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.

Does not block RFID scanners
Does not block RFID scanners. I literally scan my badge into work every day through it. Other than that, they are nice wallets, but only last about 3 years before the leather starts crumbling off. This is the second one I have bought.
2 Stars because they only last about 3 years and does not block RFID scanning as advertised.

Nice Wallet
Size: One Size, Color: Black
This is a pretty nice wallet, although calling it 'minimalist' might be a stretch. With the availability of Apple Pay and others, and the decline of cash, there is no longer a need to carry all your credit cards and money in your pocket. There is also a trend to allow you to put a legal image of your Drivers License on your phone. So as a result, wallets are getting smaller and thinner. This wallet attempts to achieve that, but actually I could do without the cash pocket and also the completely unnecessary fold out flap for your drivers license. I thought this flap could just be slipped out of the wallet, but it's actually sewn into the top of the card seam. When I received the wallet, I carefully cut off the flap above the seam, along with a ridiculous number of sewn-in tags in multiple languages, and this worked out pretty well. I can carry this wallet in my front pocket fairly easily. So for the price, I am pretty satisfied. Prior to this I was using a card case with 4 slots which I may go back to at some point. I'd have to say that unlike this wallet, the card case is truly minimalist.

Yes, Being A Man I was Forced To Buy A New Wallet After 18 Years!
Yes, I had a wallet for 18 years, I even rebuilt it with tape when parts of it were falling apart. Even if the tape didn't match the color of the wallet I'm obviously so creative that I added to that old wallet with color! I know many of you are applauding me for sharing this idea so I thank you! Anyway, this is a nice solid well priced wallet & looks like my old one minus the tape. I highly recommend it. If only I had time, I'd share more ideas like how I fixed my leaky roof.
