Here is the map from my bike. The bike is stock and has  its own lambda sensor. It runs closed loop.
This map is a result of many autotune rides and also logging for later analysis.

Many users receive this as their starting pointing.

Yes its the stock sensor and it is connected in through the wiring harness. If you look at the PCB layout you'll see the lower of the 3 pins also goes to the main connector.

I don't think it's an upmarket sensor but it does seem to have a more gradual slope than the traditional narrowband sensors.
