I did just have a look, you're quite good to go if you don't want to fiddle with that MAF calibration. Your LTFT looks good, don't pay attention to your -13 at idle and your -4,7 is in range (-5/+5) so it's good too. At WOT you are hitting your lambda fuel targets, nothing to worry there.

Cheers.

P. S. I think I didn't miss anything guys. Any advise to give to Dave?

That sounds promising then.do I need to log a wot run

Do a wot run and look at Desired afr v actual and then find the multiplier at each maf volt point.
