Sudden lean running *with logs*
Posted: December 2nd, 2012, 6:14 pm
Have a 2007 3 MPS, Been tuning it with versatuner, its got a corksport intake, autotech hpfp, forge bpv and a test pipe.
Did logs yesterday and AFR Actual was pretty much spot on Commanded.
Today flashed a new map, with no change to afr or maf cal.
And my afr is lean. for the whole WOT run the actual afr was 0.5 -0.6 leaner than commanded afr.
Been using this maf cal for months, the car had done 100 + miles on the map before the logs were taken.
LTFT at idle is < 2
Stft at idle is < 5
Logs attached, any help appreciated
