ECU Master EMU - EGO Feedback

EGO feedback
EGO feedback configuration window is used to set up EGO closed loop correction operation
parameters. Both wideband and narrowband sensors can be used for correction. In case of
narrowband sensor, it's only possible control mixture content around stoichiometric (NBO Ref
Target). Use of wideband sensor allows controlling mixture to achieve values set in AFR table.
PARAMETER DESCRIPTION
