I think you misdefined a bunch of shit and then went over it with a sledgehammer...
I fixed the MAF part, I didn't look at anything else.

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 Smiley

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.

And if you do that, then if your MAF fails or a hose pops off you will most likely be stuck with a non-startable car in the middle of nowhere...
That is weird. My car still starts and runs (but on limp mode) even with MAF disconnected with CDEHFM on 0. I turned it off as I keep getting a MAF error on VIDA (no check engine light) but you can definitely leave it on.

@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.

You can log memory of P1 ME9 with this tool https://github.com/prometey1982/VolvoTools
So you can find the reason why the error is set.

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

I released the Volvo ME9 logging in my tool. Both D2 and UDS.
Ford ME9 has been supported for a while already as well.

Is there security access required for Volvo or Ford ME9?

Ford yes.
Volvo no, it's open. You only need to pass security if you want to read from the flash.

Ford comms stack is completely different.
