Need help with Disable EGR usin Hysteresis Maps 2015 outback 2.0D

[DMY]

Hi, friends
I have a 2015 outback 2.0d euro6. I want to disable the EGR to reduce soot accumulation. I found 6 EGR Hysteresis Maps in 2015 by wols based on a 2013 file, but the 2013 file only had 4 EGR Hysteresis Maps.
Could someone help me identify what the other two maps are or some clues?
I tried to turn off all 6 maps. Are the values I set correct?
After writing the turn off file into the car, the EGR valve remains at 0, but after running for a while I receive Code P0401.
Is it an issue with my tuning, or I need to disable the DTC?

the ori and tuning file

thank you all

For off you set normally all to 0
