Default technical - O2 sensors disparity

i measured the output of my two O2 sensors with a calibrated A/F monitor and one was reading leaner than the other,

ie when swinging from rich to lean in closed loop at idle.

i replaced one sensor with a fairly fresh second hand one - so one is about 10'000kms old and the other is 80'000kms old.

just wondering if:

a. this is why my ilde swings 50rpm
b. it could affect performance in any way

TIA,

t..

Default Re: technical - O2 sensors disparity (tinkerbell)

Im in need of the technical values too the MAP sensor gives,wich value at top speed is good can i adjust there something (clean),or just buy a new one?

standard values should be for a 96 BB3 lude : 2.8V max and 0.98 @ cut off engine?
