Hi! I have an Audi A3 2.0TFSI 200hp (BWA engine) with a stage-1. The car was running great, and vcds showed all great: 0? timming pulls, good boost regulation...
Now, I have bought a new Revo intake, after install: channel 020 shows: (fuel adaptations show: 1% (idle), 6% (partial), and logging with VCDS I can see 5/6? timming pulls (channel 020).
I think intake needs to be adapted, but in the file I can't find "MLHFM" map (Typical 512x1 MAF linealization map from ME7 (20vt engines)).
I could only find "KFKHFM" (14x14).
Which map do I use in order to adapt de intake? How do I do it?
Regards! Thanks in advice!

Fix it with fkkvs or kfkhfm :)

That is why I never buy those "big name" intakes.
When you make it yourself you can adjust the intake diameter to something already calibrated. For stage 1 Audi A4 MAF diameter is more than enough

Hi! Thanks for helping me!
Ok! I will correct the maf with KFKHFM.
How do I modify KFKHFM? Ussing %? (Any picture for example?)
I think, If 032 channel is: Lambda adaptation (partial) 6,3%.
Increase (%) little by little all the map, until get at 6,3% increased at MAX load/rpm value.
It`s right?

yes correct you must fix % in this area you are to lean +6,3% you must have not more than 3% or the flap close

Hi! thanks for helphing me!
I must fix %, using "032 lambda partial adaptation" value: 6,3%, or using "001 lambda regulation" values?
I attach a log

use lambda regulation the ecu give 25% longer injection
