I'll take another stab: if KFMIRL is modified, but KFMIOP is not set up properly to reflect those changes, is the result timing oscillations?
I think u are on the right track... I've been browsing the fs but I need to do a little more digging before I test out some changes. |

misol seems well about miist, and zwbas STILL shows the same occilations. IRL/IOP are near stock.  |

If zwbas is already osscillating simply log all the inputs in zwbas to identify which one causes it.

I'm here.... timing seems to be coming from kfzwop, as kfzw is only set to 36 max at full load while i'm getting 42* which is what i have in kfzwop... first time i've seen this. I'll report back when i get it all smoothed out and figure out the cause. this is e85 +meth rs6 turboed s4... 42 is too much.  |

I have seen in my logs sometimes zwout will exceed zwbas and sometimes even appear to follow zwopt. This doesn't make sense though. zwsol is capped by zwbas. As far as I can tell, zwout should only exceed zwbas with the influence of wphg and zwdllprt. |

I'm considering changing phase response, wphn.

i made adjustments to wphn (phase response), waiting for logs tomorrow morning. I first tried scaling back both kfzw(2) kfzwop(2) yeilding the same results, just slower.
wphn map changes right where oscillations get bad in rpm range and is an input to zwbas.

Are you logging zwist? zwbas? zwgru? You need to trace it back from the output to the cause. wphn is added to zwbas before zwist and it only adds a little timing as RPMs rise. Does zwgru oscillate? If not kfzw2 has nothing to do with it. Are you logging fnwue? I think this problem comes from rapid switching between zwsol and zwbas. Also, KR is only active if zwist == zwbas. What do your CF's look like? |

cf's are 0 so not KR... i'm thinking the answer is inside of MDZW somewhere.
i think whpn is part of my issue, i want 36* and i'm getting 42*.
i have not logged these yet, as i don't have the car on hand. i will see if we can get the me7logger going.
MDZW has a lot of talk about torque influence on timing angle... recovery of angle, which outputs to zwsol.
i'm gonna do some more staring at this.

You can disable zwsol by setting CWMDAPP = 1. If that fixes it then you know MDZW is the source of your problem.
wphn won't fluctuate like that. It follows NMOT.

yeah, you are right.
I'm waiting to see how underscaling the maf works, then i will try turning off zwsol

mdzw suspicions confirmed. When i narrow down exactly which map(s) to change i will post it up.
uderscaling did nothing.

Have you done any rescaling/changing of IOP?
Seems strange that the timing is just soo agressive

i have made changes to iop for the tune, but none in diagnosing the oscillations. like i mentioned earlier, timing was being increased to greater than my kfzw values through whpn and possibly something else. i disabled mdzw entirely and no more oscillations. I've narrowed down the specific map which i'm testing tonight... i'll post up my findings.

while i'm not sure this is the best way to fix the oscillations yet dzweta has fixed them... you must tune the map, you can't just zero it or you will have other issues. it is a percentage map for timing shift under zwsol. after making progressive changes to only dzweta this is what happened to timing  |
