X-trail: 02 Sensor

I was comparing the O2 sensor signals between the X and a i10. The i10 looks like it has a more healthy 02 signal.

When i floor the pedal, the O2 signal responds shows exactly as described in scannerdanner's tutorial. As for the X, there was plenty noise & deviation from the expected signal form.

Do i have a lazy O2?

Gonna need more tutorials........
