	KFLF again... « on: June 20, 2013, 12:51:32 PM »

First wiki quote:
"Note that KFLF's description as "lambda" is a misnomer. It is not lambda at all. It is an injector on time scaling table where larger numbers are richer, smaller numbers are leaner."

So if change values from 1.00 to 0.85 I make AFR leaner?

KFLF in ME7 is a scaling factor for the conversion of predicted load to relative fuel mass.

1 would be 100%

0.75 would be 75% (25% less fuel mass required)

1.25 would be 125% (25% more fuel mass required)

And what about KFKHFM?
Small values = rich AFR?
Or like KFLF, small values = lean AFR?

Sorry for maybe stupid question, but its important to know for me...

KFKHFM adjusts how much air the MAF thinks is being ingested.

Higher means the ECU thinks there is more air, so it will add more fuel for a given requested AFR.

Like KFLF, it does NOT change requested AFR.
