Hi

Just to compare, here is a log from my cold start with "noise reduction ON" in MHD:




As you can see, my AFR falls into 10 area too then DME decrease STFT in order to keep AFR @14,7 target.

Only difference is that on my car both AFR reach 10 and both STFT are decreasing where in your log only bank2 is concerned.

I don't know why but it's like if the DME was in open loop at the beginning and then it goes into closed loop then lambda value is taken into account and STFT began to adjust fuel to reach AFR target....Then the LTFT takes over and STFT fall into 0 area....
