MB ML350 BlueTec W166 - EDC17CP46 - EGR Off with DPF on?

Postby pythons » Sun Sep 11, 2022 11:24 pm

Hello,

I am looking for someone that has experience with this ECU, what would be the correct way to turn EGR off without interfering with DPF regeneration, in total I see 8 EGR Hysteresis maps:

During EOM:
AirCtl_qHiEOM_CUR
AirCtl_qHiSlwEOM_CUR
AirCtl_qLoEOM_CUR
AirCtl_qLoSlwEOM_CUR

Normal:
AirCtl_qHiSlw_CUR
AirCtl_qHi_CUR
AirCtl_qLoSlw_CUR
AirCtl_qLo_CUR

Will zeroing EOM maps cause issues with regeneration? should only non-EOM maps be zeroed? is there a cleaner solution?

Any advice is welcome, Thank you in advance.
