I got really strange problem which I have never experienced on any other ECU then BFB/BEX.
Problem exist whenever i want to run only on LAMFA map, values are not taken to the specified lambda.
Of course my KFFDLBTS is = 0 and KFLBTS = 1, in that situation fueling should be based only on LAMFA map, but in practise i still got lean lambda.
Is there any different map which is used for calculating lambda on this ecu?
i would like to turn of egt protection, bts and only run on well prepared lamfa.

I got ZKLAMFAW stock, but as far as i know ZKLAMFAW is delaying the onset of LAMFA not determine specified lambda.

What is stock?
ZKLAMFAW is the alpha constant for the low pass filter and controls the rate of change. Enrichment will occur linearly towards the specified value using the rate of change set by ZKLAMFAW and may never even reach the target if the rate of change is low enough.
Do you have LAMFA defined correctly including the axis'?
There isn't a whole lot that can go wrong.

I'm having the same problem on an 1.8t 032LP
ZKLAMFAW set to ffff
lamfa doesn't seem to kick in until BTS is triggered.

My lamfa is defined correctly, i performed a lot of tests to check what is wrong but no success  i found KFZKLAMFA's maps at: KFZKLAMFAW_0_A at 26D88 8x6 16-bit KFZKLAMFAW_1_A at 26DE8 8x6 16-bit  Should i set those maps to 65535 ? are maps look ok? |

TLAFA?
B_lamfas?
What variables can you log from the function? lamfaw_w? lamfaws_w?

ME7L fails to detect a LOT of variables needed to debug this :/ |

Setting ZKLAMFAW 8x6 maps to FF solved the problem. Thanks! |

You can set them to something a bit lower than ffff to make it look a bit smoother... instead of a cliff...
