Big, laggy turbo, trying to numb positive deviation diagnosis. Other than EDLDRP, what are the preferred methods, specifically for ME7.5?
My file is attached.
I'm leaning towards 1A231

How different is that file's positive deviation process from the 2.7t?

So the address I thought might have been it (directly after DLUL) I now believe to be DPLPLGD
Nye: superficially, very different. DLULS is 8x1, with the addition of DLUL (single byte). Also, on the subject of deviation, anyone know the names of the time constants for overboost and underboost detection?

Bische: That address isn't accurate for the file I posted. That looks like KLDLULS (overboost deviation, which I have at 27F47). I'm not looking to disable overboost diagnosis, but rather underboost. |

Oh, I misread the SW version #. But, im not quite sure I follow here. You have set a target boost that cannot be reached, and then you want to disable the diagnosis throwing a code for underboosting?  |

I'm just having issues with underboost codes periodically on part throttle. I have boost following requested perfectly on WOT runs, I'd just like to numb deviation detection a bit so the code doesn't pop up during casual driving.

I have never had that problem, how big turbo are we talking?
But that would be handled in the map on my screenshot anyway.

Bische: I checked the map posted, my file has different values (Factor 5*x).
Also, is the axis right before it? Factor? I assume it's HPA (the axis) not U/Min like I've seen.
DLUL is deviation detection in general, not just for overboost like KFDLULS?

So I have the underboost sorted by setting LDRXN to something a bit more reasonable for such a laggy turbo. I'm still getting code P0234 (overboost), mainly when letting off after a run. Looks like the N249 being missing may be the issue here, but I need to eliminate it. I have FF'd KLDLUL (or what I believe to be 27F47, 8x1), and DLUL (1 byte), but still getting the code. Thoughts?
