New to the crew trying to learn so please excuse my ignorant mistakes

So i took Jasons file which had Tony's and Setzi's file merged and modified a few maps for my car hoping to get some feedback trying to create a very aggressive file to start with as a base for my s4. Looking  for some opinions got stuck at one part maybe someone can help.
Car setup is currently
S4 M-Box: E85 - Franken Turbo- ID 1000cc - 4-bar - 044 - RS4 MAF


I have modified the following in the file attached "DID NOT TEST IT YET HAS CHECKSUM ERRORS DONT NOT USE !"
How do these numbers below look ?

Map           Value
KRKTE   0.03763
MLOFS   200
CLACINS   0
Nmax           7500
CDKAT   0
CWDLSAHK   0
CDHSH Q   0
CDHSHE   0
CDLATV    0
CDLASH   0
CDLSH    0
CDLSHV   0
CLRHK    5
CWKONLS   17
CDSLS   0
CDTES   0
CDLDP    0
FKHABMN   0
CLALSH   0
CLALSH2   0
CLRHKA   1


I am having an issue with MLHFM i have the maf comparison sheet and the volts don't match the ones on the MLHFM maybe this is a dum question how do i go about editing this.

I believe the base file you are using is already scaled for an rs4 (85mm) maf

..........

Paste stock table into excel
Measure stock maf diameter or look it up on s4wiki
Calculate maf area for both stock and whatever maf you're using with Pi*r^2 formula
Calculate multiplier between areas
Multiply all cells of stock maf by that multiplier
Paste back into Tunerpro or whatever you're using.

Cheers.

I thought most people were having the best luck scaling by a ratio of the diameters, not the cross-sectional area (though area makes more sense)?

For me, turns out area was more accurate, but ran me in to the ps_w limit sooner, which was causing problems.

Either way some underscaling (either global, in MLHFM, compensated for by KRKTE, or selective, in KFKHFM, compensated for by KFLF) is required.

Currently, I do a combination of both.

You think he'll hit the ps_w limiter on k04's?

Do you want a log from my RS4? Smiley
But the better answer is, if you have meth injection and you want to really take advantage of it, you certainly will.

On pump gas, you will be barely OK.

I have to check my laptop I think I have a file you can reference to for some help.

 I ran 850cc ev-14s at 4bar and one 044 on f4hs but used a 90mm Maf.
 I also have a 1000cc ev-14 file that I run one 044 w/ 85mm maf and gt28 eliminators with 68mm billet wheels.

Message me and I can try to help you out with one of the two files as a base.
