OK then....
It's going into CL, that's good.
LTFT's are positive, but STFT's are -ve, this is why we need some log data. It may be nothing, but who knows.....
It might just be the final ratio change that's causing issues though. If you have gone from 2.77:1 to 3.39:1 and not updated the transmission calibration to suit, then it'll be shifting at the wrong places. It may be locking the TCC too early and making the car labor a lot more, causing it use more fuel.
