The DIY-WB Controller Project Information

Note: The WBO2 project is defunct, and these pages are no longer being actively maintained.

A typical OEM switching type O2 sensor will not work with this project.  This project requires a 2 cell wide band O2 sensor that was used on some lean burn Honda Civic's, more info can be found below under Sensor Info.
