Summary of change:
'''Free air calibration procedure''' First '''calibrate 1st WBO2 with''' * Wideband settings / '''2nd WBO2 = disabled''' * free air (of course) Than enable 2nd WBO2 and calibrate "Second" WBO2: * Wideband settings / 2nd WBO2 = disabled * free air (of course) ---- NOTE (errata): * if 2nd WBO2 is enabled * always restart ECU before "Start calibration" ** it was reported that with fw 1.2.31 Dual WBO2 (2nd WBO2=enabled) Tools/WBO2 calibration Stop and '''reStart''' calibration after previous attempt and >1 minute: only 2nd heater starts to heat rampup, even if "FIRST" channel is chosen in VT (weird). ** "Start calibration" after ECU reboot => both heaters ramp up ** But recommended to calibrate first WBO2 with 2nd WBO2=(temporarily) disabled, see above. ---- If in doubt, check that the wires go to the correct WBO2. * pump- and +12V are shared, but other signals should be connected to the appropriate nernstinput, pump+ and heater outputs.
Optional: Add document to category:
Wiki formatting: * is Bullet list ** Bullet list subentry ... '''Bold''', ---- is horizontal ruler, <code> preformatted text... </code> See wiki editing HELP for tables and other formatting tips and tricks.
