Its a great effort Swingtan, Thanks there are some great ideas in it.
Just a few suggestions for consideration.

Paul has suggested that the best way to go mafless is not 1, 1 approach, it might be better to reverse the highs and the lows. ie. swap the 13500 and the 10. There have been some mystery problems in some cars that are set with 1s.

I also edit DTC Type P0101 P0102 P0103 from B to C (not reported)

Also a tip for Forced induction people beware of a weird effect of burst knock activation mid acceleration not just at throttle tip in.

Also DFCO delay in M6s is set to 0.1s. This may have been a mistake in the stock calibration.
