For some reason my EGO never enables during driving. Uploaded a log for review.

Hello AnttiKo,

I have reviewed your vemslog: v3.3_u019109-2020.12.10-07.13.31.vemslog, the ego does not enable because the wideband circuit indicates the wideband sensor is not ready for use (meaning either heater or pump control is too far off target to be accurate). Status can be monitored via the isO2Ready Flag in VT, see: http://vems.hu/vt/help/v3/flags/iso2ready.html

To determine the root cause of the control problem, please proceed as follows:

I will review and get back to you with my findings

Best regards, Dave
