The Revel VLS Wideband A/F Ratio gauge utilizes the best in sensor technology with the included BOSCH 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.
