Great news! I wanted to compare what it produces to the scaling I have. Thanks for the excellent tool.

hello guys,

You can change this little program for me 3.8.
Have the conversion values ​​for 256, rather than 512?

thanks in advance.

Hello,

thanks for the reply.

I tried in every way but does not work with me3.8.3.
With ME7.5 works perfectly.

I can do some particular task?

New version uploaded! Thanks to you guys I was able to find the bug when used on Hitachi MAF's.
Redownload and use, should work now! Smiley

Also, added a new option for TFSI Maf (PWMMAF)

Usage:
mafadjust.exe 115ab.bin 65 72.8 0x1c50e6
mafadjust.exe 115ab.bin old_inner_diameter new_inner_diameter offset_MSHFMTPH



Very cool, thanks for updating!

If you increase the area why does the value initally decrease then when you use the utility?

MLOFS is non zero.

do the math yourself and you'll see why. shift the whole thing down by MLOFS, scale, then shift it back up. The regions that were negative when shifted will be MORE negative scaled, and less positive when MLOFS is added back in.

alternately, you can leave it in place without shifting, and leave MLOFS zero, and then scaling the MAF is always a single operation

I scored a free 3" MAF housing from an A6 so I had to put it on my car and give this program a try. Worked excellent! Car has never run better!

Thanks a bunch for this utility guys!

Hi,
I used mafadjust on a 7.3.1 Alfa Romeo 147 GTA
the output values appear incorrect:

MLOFS is 200 kg/h (2000 in map), and the program does the calculations as if it was worth about 59..

Example: diameter 70 to 78 mm (+24,16%)

Minimum value in the map is 1385 (138,5 kg/h)
1385-2000 = -615
-615 * 1.2416 = -763.6
-763.6 + 2000 = 1236.416

The program says 1281

Maximum value in the map 14791
14791-2000 = 12791
12791 * 1.2416 = 15881
15881 + 2000 = 17881

The program says 18364

What is wrong?
