Hi! the problem appear after i changed the turbo and maf (k03 hybrid with k04 internals and 3 inch maf housting and my stock maf senzor)
the problem is next: when i,m at idle esp light is on and my dtc is maf signal to high,, i transfered the mlhfm values from a bam file in my bin, i transfered the kfmldmx values too, is a bosch maf sensor, mlofs is 200 like in the bam file,i increased the mlmax to 950 , the only maps wich is stock is kfkhfm and fkkvs, and i stil have this dtc, i tried to flat kfkhfm at 1 but still have that fucking error
if i add back the `stock` file (not touched in maf area) and the bigger housting fitted i dont have that dtc at idle
i attached the `stock` bin, the kp and the tuned bin in maf area and a log
Thank you so much!

You're way past the end of your boost sensor. Don't do that

Also, log ps_w

Copying other people's modifications blindly isn't a great idea. Also, some maps in the file are so badly defined that your engine ends up running totally retarded. I'd suggest reading the S4 wiki tuning from scratch and abandoning the mods seen in other people's tunes, especially if you don't understand why those changes were made to begin with.

I have no logs because I have a boost gauge (makes things easier)

Don't go over your MAP limit. DO NOT BLINDLY DISABLE DTCs just because you have no idea what is going on.
