E_lm is not the bit you need to modify.
As for the rest, I don't care how you are doing the alpha-n solution. Alpha-n is for losers, like running the ECU permanently in limp mode.

There are public A2Ls for the "MAP sensor only" ME7 ECUs, so you can disassemble those and figure out the "factory" way to running a secondary (or, in fact, now primary) MAP. Search for "SY_DSS=1" in A2L tags. I was planning on researching this, but didn't get to it yet. It's also a good idea to search for the magic "DSS" abbreviation in the FR to get an idea of how it is supposed to work. ME9 FR shows some more detail.
Although hacking GGHFM, DHFM, etc seem like an easier way - but that's still a lot of work.

The only thing you use GGHFM and DHFM for is diagnosis, unless you want to roll your own.
I don't see the point when everything is already there. Simply make MLHFM linear and fill KFMLDMX and LDMN with sane pressure values, so that if sensor is screwed it will switch to the pre-throttle one.
The MAP signal into load calculation has to be done differently of course, that's all custom code - you will have to rewrite BGSRM.

I'm in the same situation, i'm running mafless well, the car is perfect, run faster... but the ecu is in limp mode,esp light on and not working, 50/50 brake etc... I think i need the patch to apply for a ME7.5 . Is there anyone here willing help me to understand what to do to interrupt the can signal, or this E_lm thing? Thank you very much |

No. Just no. Please stop spreading this idea that MAFless is somehow magical.IT IS NOT. As for the rest, I don't care how you are doing the alpha-n solution. Alpha-n is for losers, like running the ECU permanently in limp mode.

It's not magical but i'm running mafless and i need to correct this limp mode without esp and brake fully working  |

This is not an answer and solution. I have intake filter and turbo of 101mm (4") ... i don't wanna use pipe reduction to mount a little maf moreover scaled. All the great street cars with world record on drag race or 100-200 , 100-250 are running mafless... so... it's not as bad as you are saying. My car have 701,4 HP, 666 WHP and 723 N of torque.  I don't think is going bad |

You'll never solve all of the other problems without a proper MAP sensor.
Or, if all you care about is trap speed and dyno queen numbers, then thats that.
IMO that isn't what proper tuning is about.
If it was, we'd all run standalone, drag radials, and solid rear axles.
