Controller specific values:
- wbo2_nernstdc_target=86 # controller specific (controller not sensitive to very precise setting), usually 0x86 gives most precise 0.45V between nernst and pump-
- wbo2_pump_pw_zero=65 ## controller specific. Look up webshop mail (or calibrate for your controller for minimum pump current
- See MembersPage/Sprocket/WideBandRiTarget for historical wbo2_ri_target=96 (decimal 150) value, 160..180 (say 170) since firmware 1.2.0

Calibrate yourself in free air, after replacing the sensor!
- wbo2_calibration=40
- start from lower values and increase as necessary
- starting from way too high calibration value might result in "out of range" values, preventing proper calibration. So do NOT start with a 255 value. 10..64 should be good starting point (lambda and O2 will reading will be incorrect before calibration, as expected... The purpose of calibration is to show correct, verified value)
- start from lower values and increase as necessary
