lambda - free to air calibration

[Seight-v8]

hello all,

What type of variance in the readings should I be getting when doing the free to air calibration under the WBO calibration?

Two new lambda sensors.....but they are flickering like mad.....

Anywhere between 17-24%, and cant seem to get the readings stable enough to burn them too the ECU.

Is this normal?

Just wondering if I should send them back or whether I have more problems?

cheers

Bounding by 0.1 is normal, much more than that is not
