Default MHD flash problem - 12-02-2020, 03:33 PM

Hi, today I flashed my 335i 08 n54 stage 1 map, the idle was really bad, staying around 500rpm and vibrating, I reverted back to stock ecu. same problem. then driving I got engine malfunction, checked codes and cylinders 1,2,3 misfiring. also other codes like 2c77 oxygen sensor after *** converter, 2fa3 no coding. any help is appreciated.

Mofsets in the dme may have went because of it's misfiring on entire first bank.
