Grams Performance G2-99-0055 Wideband Air/Fuel Ratio Gauge

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.

Features

52mm Gauge Housing

Bosch 4.9 LSU sensor with weld-in bung included
Accuracy down to .001 and 4 digit display

You can expect the same up to date technology for future Grams Gauges such as Boost Gauges and Oil Pressure Gauges.

I purchased a BakFlip F1 truck bed cover, they had the best price I could find anywhere. Their shipping process is very fast. I will look to buy from them again.

no issues. good prices. The above was automatically input for me. However I don't feel as though its accurate. The part about no issues is correct buy the prices... Well the prices really weren't good. They were the best.

I had a great experience ordering my springs through Autoplicity. I received instant notification of my order as it was placed. I was very happy to see shipping information so quickly after the order was placed, also. Last, but not least, I received the springs SO FAST! Best price, instant notification of order status, fastest shipping, therefore best review that I can write! Thanks, Autoplicity, I will be a return customer if I need anything else!

The product came at the very last minute. So we had to do something different plus the "return" directions on the website were not clear, i.e. the return process is not easily executed.

Very quick. Liked that it linked to Amazon. I originally ordered from Amazon who shipped me a front bearing assembly instead of the rear so having to re-order from you. Correct item received this time. Thank you!
