Thanks for the info.
I have a  problem which i dont understand.
My AWM maf Reads right now 188 g/s and sensor voltage 4.6 - 4.7 and never went above. So i upgraded to TT maf.
What combination should I use ?  3" Maf with AWM sensor or with BAM sensor ? I have already changed  MLHFM ,MLMAX from BAM.
I ask this because at start i tried 3" housing and awm sensor. Result was 152 g/s and 4.1V . It seemed strange too, should it not be greater than 188 g/s ? Anyway car drove good and fuel maps were good.
After that i switched to TT sensor and the result is : 163 g/s ~4.2V . Fuel maps were not so good.
The reason i was switching sensors was that my logic told me that the readings should be greater than 188g /s as from logs it seemed maf was limiting factor.

Well you are maxed out out MAF then. Either upgrade housing or the whole MAF. you will need to rescale maps , like said above.

I rushed for the exe rescaling file too soon. After just using mafadjust, log file seems still a little bit strange. I started to read wiki and found out that i need MLOFS also for rescaling.

No you dont need to change that map, you read it wrong. Only change it if changing from a hitachi to bosch maf.

Thank You for the info. So i need to use only mafadjust.exe ? I will check if i made some mistakes and try it again. Seemed wrong as, after scaling maf was reading 166 g/s. Old one went to 180-190 g/s.
Sorry for dumb questions, as Maf was not limiting me before and now it is, i am starting to learn it  Grin

Well i guess i messed something up with ID numbers.

Did you measure MAF iner diametar? Schloud BAM have 2.75", and standard 1.8T 2.25"

Second, you have 0.7 bar boost at 6000 RPM with K04, how you think that will result in higher flow than 160 g/s?
Give him boost, than you will have more airflow
