dmaufr_w 0x382E7A
etazwb     0x380CB4
dmllr_w    0x3827F0
dmar_w    0x382898

I'll look into the others later.

actually, im missing zwbas... i only have zwbasar_x

so zwbas and dzwb

ETA: miopt would be handy too, just to make sure i'm not hitting some weird miist that is too high for mifa.

zwbas     0x00F9F9
dzwb      0x380CAD
miopt_w 0x38296C

Fyi...ETADZW is not read as a table. If dzwb <= 0 then the first member of ETADZW is used, if dzwb >= 48.75 (#41h) then the last member is used, else etazwb = the first member of ETADZW - dzwb.

Awesome.

I can't wait to get my car back now.. I am sure I can figure this out.

Also just as a sanity check - B_mibeg is 0, which leaves:
 
B_LSD
B_MDEIN

any other torque intervention state bits I should be looking at?

Update:

I'm seeing a lot of B_zwvs activity, but not B_zwvz (B_zwget and B_zwnget are both inactive)

Which leaves dmar_w and B_llrein

UH. why is B_llrein on??? isn't that idle regulation? and isnt dmar_w anti-judder?

ETA: I'm seeing the swings in mizsolv. mibas is solid. i can't log etazwb.

im pretty sure the culprit is dmar_w then :/

ETA: just logged dmar. its definitely activating. a lot.

Ok. Looks like the next step is to log:

mkar_w
dmarv_w
ndar_w
mdbes_w
mdverl_w
mlast_w
fdar
nmod_w
ndiff_w
B_ar
B_dashv
B_in
B_tvars
B_lsd
B_fgr
B_wk

UPDATE: information i received from a tuner who was kind enough to help me out

mkar_w, Berechnetes Kupplungsmoment fr Antiruckelfunktion, 38289E
dmar_w, Delta Drehmoment antiruckel, 382898
ndar_w, Differenzdrehzahl fr Momenteneingriff, 3828A2
mdbes_w, Beschleunigungsmoment, 38289C
mdverl_w, Motor-Verlustmoment, 382984
miistoar_w, Istmoment ohne Antiruckel-Anteil, 382A18
mlast_w, gesch,,tztes Lastmoment, 3828A0
fdar, Verst,,rkungsfaktor des AR-Eingriffs, 380CA0
nmod_w, Motordrehzahl aus Modell, 3828AE
ndiff_w, Differenzdrehzahl fr LFR-HS-Verst,,rkungen, 3828AA
B_ar, Antiruckeleingriff aktiv, FD9C
B_dashv,Bedingung Dashpot verz"gert, FDA0

unfortunately as you can see i'm still missing bit positions and scaling (in particular, dmar might be tricky, its a signed load, and ndiff is a signed rpm)

Update:

The RS4 maps are very different.

KIFZGHG is much stronger (rpm model) and KFDMDARO/DADP are much looser (allowing more leeway before AR kicks in)

I may start by just copying those maps over.

to which maps are you referring?  i've been on the kfmirl/kfmiop/ all pid maps for a while now...
i can share my maps, because they need to be interpolated correctly to work so its not just a matrix copy.

Uh.

KIFZGHG and KFDMDARO/DADP

ETA: also possibly FLRHG, which is the scalar for feedback of error back into the rpm model. There are three in the RS4 f-box, two of which are significantly higher than s4
ETA: nvm, FLRHG isn't that different

Success. I copied KIFZGHG, KFDMDADP, and KFDMDARO from F-box rs4.

No more ARMD intervention
