O2 sensor
Narrowband O2 sensors (the ones that come on the car stock) only function in a small window of around 14.0 to low 15s. Any different fueling than that they can't read, so for example if you try to tune wide open throttle in the mid 12s those sensors will not be accurate.
Wideband O2 sensors have a much wider (hence the name) window of functionality so they can accurately read fueling as low as 10.0. So you can tune wide open throttle and know that the data is accurate.
