The Revel VLS Wideband A/F Ratio Gauge utilizes the best in sensor technology with the included LSU 4.9 oxygen content and Lambda value sensor. While many aftermarket wideband gauges are still operating on the older, less accurate sensor, OE manufacturers and Revel VLS have made the switch to LSU 4.9, the new standard. Compatible with gasoline and E85.

This sensor is longer lasting and is accurate to 0.1 AFR reading and does not require to be free-air calibrated upon initial setup* (however it will still need further recalibration based on altitude changes and general sensor wear in order to ensure accuracy). This is a major improvement over the previous LSU 4.2 sensor. The kit also includes the weld-in bung that is required for the installation of the sensor.

Maximum comfort is attained by the use of an OLED (Organic Light Emitting Diode) numerical display. When compared to a traditional LCD display, the OLED display provides sharper contrast resulting in a deeper black for a crisp, clear images that is easier to read at a glance. The technology also allows for undistorted viewing angles approaching 170 degrees. The OLED display also does not require a backlight to be clearly visible at night, which gives the slim profile of the gauge. All Revel VLS gauges include the necessary hardware, sensors, and universal mounting pod and hood, as well as the installation instructions.
