Also car died while turning left from the signal. The log shows RPM dropped to zero.
After couple of logs and because of surging issues, changed idle airflow, changed etc scalar area, trying to dial in MAF. But nothings helping.
Also second and third gear as i start pressing gas it seems like around 2650 rpms car is trying to apply brakes as if trying to limit torque, not sure how to put it in words but unless I change into next gear car runs really weird.
In need of help to understand whats going wrong
