Too much overlap in 4500 rpm and onwards. Need to change cam timing to correct. - Install Ibutton reader for immo. - idle air valve --- For some reason my EGO never enables during driving. Uploaded a log for review. http://www.vems.hu/files/AnttiKo/ ---- 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: * in knock sampling settings, change realtime data option to: adc/individual power * take the wideband sensor out of the exhaust in free air * start a vemslog * than start the wideband calibration from tools -> wideband calibration * leave the log running for a few minutes until the wideband has fully heated up and pump control is active. * stop the log and publish it in your FileArea (linking here) for review. * you can change back knock sampling settings, realtime data option to previous setting. I will review and get back to you with my findings Best regards, Dave
