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 ---- '''Sensor specific''' - See GenBoard/Manual/Config/WidebandCalibration 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)
