got a problem with RS4 cause it does not follow the LDRXN curve. There is something like a wall at rlmax_w 204 but LDRXN is about 215. KFLDIMIX is not the issue Knock is not the issue I think it has to be something like a min restriction an not a factor because I can raise the values in LDRXN up to whatever I want, it stays 204...  ldrlms_w ldrlts_w nmot_w plsol plsolr_w pvdk rl rl_w rlmax_w rlsol_w 126,703 269,578 4599,75 2350 814,063 2340 191,25 209,211 204,11 204,11 |

There is an entire function for this purpose!
Look at LDRLMX
Edit: i see you're on the right track, but those values aren't exactly legible

I can tell you that there's no mystery there.
Have you logged rlmx_w?
Log as much of the function as you can.
Looks like you've narrowed it down to knock (fldrrx_w), coolant temp (frxt), and IAT (frxta_w).

maybe no mystery but I see the unwanted result  no, unfortunately no rlmx_w... but I have absolutely no knock retard (dwkrz_0-5 = 0) in this area and my LDRXNZK is all 100 |

Your problem is most likely KFLDHBN.

That was my first reaction as well, but it looks like ldrlts_w is 269.5 above. |

I thought about this if I make a mistake by understanding the values of KFLDHBN but I can not identify the connection of KFLHBN and LDRXRN in my log seems to be high enough: ldrlts_w nmot_w plsol plsolr_w pvdk rl rl_w rlmax_w rlsol_w rpm mbar mbar mbar 268,406 4348,25 2370 836,484 2050 180,75 181,336 202,898 202,898 257,086 5795,75 990 0 2370 127,5 128,18 204,211 55,2422 (Wped = 0 after acceleration) ldrlts_w falls and rlmax_w is rising and vice versa |

ldrlts_w falls and rlmax_w is rising and vice versa
Just set it to FF and test.... Easy  |

I have no logs because I have a boost gauge (makes things easier)

Stop futzing around and post complete logs (and/or graphs from ecuxplot) and the contents of KFLDHBN

ldrlts_w (from KFLDHBN) is 269.5 which means that KFLDHBN can't be the problem.

I have posted it above. ldrlts_w -------- why you calling it futzing?  I'm trying to solve it step by step. |

So, KFTARX - not the issue - cause 1,01 in temp area KFTARXZK - not the issue cause 0,5 in all areas and no dwkrz_0-5 so no negative frxta_w influence KFFKRXTM - not the issue - cause only active above 116 deg C tmot FKRXTOL - not the issue - cause all values 1 - so not active so no negative frxt influence KFFLLDE and KFFWLLDE and KFFLDEO and KFFSLDE - not the issue cause no dwkrz_0-5 so no negative fldrrx_w or fldrxo_w influence And these values are factors so they would not result in a static rlmax_w value 204. They would influence the curve. Next KFLDHBN - far above LDRXN as you can see in ldrlts_w, so not the issue LDPBN - not the issue cause low under 204 (ldrlms_w) and not active LDORXN - not the issue - if this map hits in it will restrict rlmax_w to 90-114 KFLDRXO - not the issue - cause in RS4 oem all 0 so not active and additional TLDOBAN all zero So what else ?? I think I have to log other values someday |

Perhaps ASR is intervening?
