Yup, I started defining the .kp before throwing everything into IDA and making sure about placement of all maps and I understand that the definitions are a mess. I'm very thankful for your time and help

EDIT: I'm also eagerly waiting for support of Volvo ME9 in your logger, it will help a lot!
EDIT2: Looking at it I have just made a mistake with MLDHFMKO and MLDHFMKU in the version that I've sent, rest was carbon copy from Focus RS bin. But will test and report.

@prj, flashed your fix, still the "limp" occured and the error code came back

@cheekano, also tried setting CDEHFM to 0, but then the boost solenoid duty cycle stayed at 0%

Consider this issue on hold, for now I'm waiting for prj logger to properly check what's going on in the ECU. Unfortunately VIDA/Volvo DHA doesn't give any useful information.

Sent you a PM, but if there is any other more comfortable way to communicate with you I would like to switch to it.

Is there security access required for Volvo or Ford ME9?

Issue fixed and the culprit is shown on the screenshots below
