Hiccups are still there with halved KISRM. I am getting mysterious PS_W drop with associated RL_W and fueling going awry per my wideband O2 although ECU things everything is ok, of course. NWS switchover is at 4k and I see associated activity so I don't think this is the culprit, but here is the KFURL as requested.
Please look at my log, row 88 and 89. PS_W drops again and so does RL_W... I will welcome any suggestions.
Edit: I will log pvdkds_w to see if I am not hitting psmx_w (I don't have memory address for psmx_w, but pvdkds_w will suffice) and therefore limit the ps_w.
this is curious |

*FACEPALM*
Mystery solved... my KFMLDMX table was not adjusted from old stock sized intake tract and now with all RS4 or larger stuff my MAF is hitting new heights. I hit and exceeded flow threshold in this table. ECU switched to normalized flow and hence the fueling going off. Obviously I need to massage the tables for MAFless path, at least put them on the rich side so that engine doesn't blow up when maf readings are off.
Curiously enough, I remember getting beeps and check engine light combined with limp mode when I had this happening previously and I am not sure why this time around this didn't happen... maybe there is a certain threshold you need to go over to get that (too lazy to follow FR on this).
This issue is solved then.

Def. work on those throttle maps. When calculated and measured are perfectly parallel, it makes me happy.

psmx_w should be 0x382188 0.0390625 though I understand you'll do without it. Just working on my IDA skills. Might help someone else. |

Does anyone know if the limit for KFLDHBN is 4 bar?
I think I've run into the limit of requested boost pressure ratio again.
The stock setting was 3 bar which I raised to 4, but now I'm requesting 4 bar and the max value it will take in TunerPro is 3.9844, which is FF in hex of course...
So this is a slight problem lol. Can we internally scale KFLDHBN?
And yes I'm really running up to and including 40psi on the street - which seems to be the limit of requested boost I can get lol.

Sure you can, shift pu left once before it gets multiplied by the kfldhbn value, done.

Incorrect the KFLDHBN is still limited to a pressure ratio of 4. So even with a 5 bar requested boost will not go above 4... that's my problem lol. |

I'm fully aware of the 3.9844 limitation imposed by KFLDHBN, I was referring to bische's post about the 10k mod. |

Fair enough lol yeah 5 bar map sensor is enough... |

I figured as much. 58.8psi is not an insignificant figure. I think to cross that threshold reliably we'll be taking about beryillium pistons, F1 inspired rods and a titanium crank. What does setting KFLDHBN to 0 do? |
