Just posting to make sure my calculations are correct and that the values spit out by excel look accurate.
I scaled MLHFM by taking the area of the old MAF ID (pi*(2.340*2.340)) and area of the new MAF ID (pi*(2.850*2.850))
then divided them.
(pi*(2.340*2.340))/(pi*(2.850*2.850))
17.202/25.518=.6741
Does this look right?
Then i subtracted 200 from each of the 512 rows (my map pack actually doesn't have an address for MLOFS, anyone know it? I believe its a HS box 1.8t. I do know that the MAF is Bosch so I calculated under the assumption that MLOFS is 200).
Then I multiplied those numbers by .6741. Then I re-added 200 to those numbers.
Sound about right? This is what i got:
First column is original OEM MLHFM, second is post all calculations.

Does this look about right? Also, I'm a bit confused regarding cleaning up KFKHFM and FKKVS. I'm trying to install and calibrate components one at a time so If i'm just scaling the MAF, I will only need to touch KFKHFM? or will i need to tweak both?
So, the procedure would be, drive 10-20 minutes idle, part throttle, logging STFT.
Then you tweak KFKHFM cross comparing where the STFT is not 0, find what rpm and load corresponds to that point and decrease/increase the value of that cell gradually. Relog and repeat until STFT at idle/Part throttle is close to/exactly 0?
Does that sound correct?
Also, could someone remind me the logging variable for STFT?
