# Fast O2 Sensor, Lsu 4.9 Wideband

This Wideband oxygen sensor is capable of measuring air fuel ratios much more accurately than a factory Narrowband sensor. This enhanced accuracy leads to more accurate tuning and more power and efficiency. The FAST LSU 4.9 sensor is accurate to Air/Fuel ratios as rich as 4:1 and 20:1 lean and is a direct replacement for the sensors provided with the FAST Wireless Air Fuel Meter.
