The O 2 sensor does seem to be disactivated but there is no option in the control flags to activate this. The car runs pretty good at full operating temps cruise is about 14.0 :1 and at idle its about 13-14:1 so im pretty sure i have the K in more or less ball park and the MAF scale more or less i have it scaled in the mid 30% HPXN1 TP stays on scale at idle and at full throttle but does hit the last column at full throttle. It does hit 25% fts when you first start the car and drive it then for some reason it goes to 0% and its perfectly fine . I noticed it was going from 25-28% to 0% all at one big step no in between.
Thanks.

Yes the O2 flags descriptions for Z31/VLT were removed. One which was previously labeled would then result in 25% and step down if deactivated

Ignore the O2 STFT/LTFT values outside of cruise as the ECU only seems to use them in closed loop. File looks okay otherwise
