I personally disable it and control everything with LDRXN  i have been running kfldhbn disabled...and so far so good, but lately i have been thinking of tweaking it |

I really takes almost no time or effort to preserve this function and not have any intervention during normal operation.

I agree. It is not a terribly complex map. If you have to 0xFF it, I shudder to ponder your understanding of more ... subtle.. maps |

So this is what I've been experimenting with (KFLDHBN based on the RS4 one with the RPM axis changed).

nyet, i originally was trying to make use it, but ended up disabling it to see if it was the cause of my issues, and it was, at the time i had very poor datalogging capabilities, but now that i actually can log, i will be making use of it......

Set whole table to 3.09 |

So as far as I understood LDRXN has higher priority than KFLDHBN, yes? |

There is no such thing as "priority"

If you have KFLDHBN FF'd, god help you when you venture into a higher elevation. At 10,000 feet your car will be requesting 30psi to try to hit requested load.

It's unreal sealevel for me, I don't live in mountains  But any case I've understood you, thanks! Guys please clarify: if LDRXN=160 and KFLDHN=2.9 - result boost will be limited by LDRXN or by KFLDHN? |

ME7 works on requested load. At altitude it takes more boost to produce the same load. At sealevel 19psi might produce 170 load, whereas at 5000ft it may take 25psi. KFLDHBN limits requested load to prevent excessive turbine shaft speeds.
In short, requested boost is limited by both LDRXN and KFLDHBN.

But also look at a compressor map for your turbo, find the 2.9 compressor ratio and see if its even on the map or any where you want to run a turbo! Especially at sea level! I can almost certainly say if you run a 2.9 you will either be surging or so far outside the compressor efficiency range it will have probably over speed its self already long before 2.9 is reached. At sea level surge will almost occur before over speeding exists of the shaft. If you encounter changing the compressor wheel is an option. If you maxed your table then ldrxn and surging is the limit but you'll hear that . |

I plan to run KFLDHBN as a sole load limiter map in my tune, this is with tial 770s, 4bar map and 5120 hack naturally. This way I should always run at the psi I want, instead at what car wants.
