Heres my Linux wideband monitor program for the Australian made WBo2 wideband sensor driver, specifically tested with the 2J1 unit. this program requires the wxPython interface modules..

# apt-get install python-wxgtk2.6

The program only prints out the wideband readings in a fairly primitive but usefull fasion, better than nothing! it's really hard to find a good graph library in python/linux/wxgtk, maybe there will be some better defaults in python QT interfaces, but we will see.. anyway, happy hacking! The tarball for this project is attached below..

Obviously, the higher the AFR (Air Fuel Ratio) number the leaner (more air per fuel parts) the fuel condition, the lower, the richer, I aim for 11:1 to for power under acceleration and 13:1 or 14:1 for cruise.
