Zeitronix Wideband O2 Installation


A Wideband ozygen (O2) Sensor (and Controller) are used to measure Air-Fuel Ratio (AFR) of your engine which allows you to tune the Fuel Maps in your ECU using AutoTune in the Woolich Racing Tuned software.

Modern engines measure the amount of oxygen (O2) in the exhaust gas coming out of the engine, this information is then used to calculate the Air-Fuel Ratio (AFR) which the ECU then uses to control the amount of fuel delivered to the cylinders.  Most bikes have a Narrowband O2 sensor installed from factory which only has a limited range of AFR readings (about 14-15 AFR), this is only really applicable to cruising conditions and does not allow users to tune their engine to achieve more performance etc.

Wideband oxygen (O2) sensosr allows measurement of AFR in the range of about 10-20 which covers the entire operating range of a conventional engine.  Wideband sensors are then a valuable tool for tuning fuel maps to achieve a specific goal (eg. better fuel efficiency, lower emissions or more power).  

Woolich Racing sells Zeitronix Wideband Sensor kits to allow these to replace the Narrowband sensors on many bikes, which allows the full advantages of the AFR and Autotune capabilities to be realised. 

This video details how to install it a Wideband O2 Sensor onto your bike. 

You can find more detailed step-by-step installation instructions for your Zeitronix Wideband kit in our User Guides and Installation Manuals page.
