Wideband vs. narrow band sensor
A wideband oxygen sensor is a sensor that measures the ratio
of oxygen to fuel vapour in the exhaust leaving an engine. The measured ratio
is expressed as parts of oxygen to fuel. If there is 15 parts of oxygen to
every one part of fuel, this would be expressed as an air/fuel ratio of 15 to
1, or 15.0:1 or to be exact 14.7kg of air equals to 1kg of fuel. For CNG the
ratio is 16.2:1.
The wide means the air/fuel ratio can be measured at a very far-reaching range
(often from around 5:1 up to around 22:1).
Wideband sensor installation:
There are three parameter/variable should be considered when using a wideband sensor;
1. Accuracy is top priority. If the wideband's readings are inaccurate, you may make fuel adjustments in error resulting in a loss of power or even worse, engine damage.
2. Speed. The wideband must be responsive to changes in air/fuel ratio to allow accurate fuel adjustments for changes in engine rpm and load.
3. Ease of installation/ Compatibility. The wideband oxygen sensor must be compatible with your tuning software, hardware, and installation needs.

Narraow band:
NARROW-BAND sensor) can only measure the air/fuel ratio over a very narrow range (often from only around 14.5:1 up to 15.0:1).
