the standard 02 sensor is a 0-1v output and it is not linear. It has flat spot in the middle and that is why cars that use that output need to bounce back and forth between rich/lean at some frequency.
The technology to make the wideband became cheaper and now most cars use it, it gives better output so you can get better tuning and for OEM's that means better fuel economy.
The voltage span of reading. A narrow band reads between 0-1V. A wideband puts that signal under a magnifing glass and reads 0-5V.lexusaltezza said:What exactly is the difference between a wideband and a regular air fuel gauge? There is obvioulsy a big price difference, so does that mean a wideband is more accurate?
Limited span widebands like the stock RSX Type S O2 sensor.aemjr said:What i've heard somewhere is what ppl were calling "semi-wideband" not sure though. This was used on some oem applications.
