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.
