Car is having bad O2 sensors and no matter what can be adjusted the STFT adds 25-30% , tried to disable the LTFT but the STFT still adding fuel.

Anyone had the chance to disable them ? Maybe messing with B1515 , B1516 or B1517 .

I'm seeing some missing tables comparing to HPT which can be run in open loop .

Stock tune is attached .

Disconnect the O2 sensors while tuning.

Did you get the .calz? Pretty sure the tables you asked about got added for testing.
