Hmm. In my case, it can't be zwsol, since my zwbas displays the crazy oscillations.

back to the drawing board. zwsol shows the same oscillations as zwist Sad

wkrdy and zaldy are both solid zero.

miist is well below misol

etazws shows A LOT of activity

another graph showing etzws interfering with zwsol, whch is often lower than zwbas.

i think i need to log mibas?

or is this a just a matter of me fixing IOP now

I'm **really** busy at the moment but would like to find some time to look into this. They are some serious oscillations!

You are using N75 still yes? Can you paste up your IRL, IOP and LDRMXN please?

yes, n75, slightly underscaled maf

Does misol come from IOP?

If so, my underscaled load might be resulting in a misol that is too low?

In which case, the advice to LOWER IOP is actually wrong, and i should increase it?

disregard. misol has NO effect on this, nor does playing with IOP.

IOP does not appear to be the source of these oscillations

Ok i made two files

one with IOP maxed (99) for 3000rpm+ and 191load+
the other with stock iop with ONLY shifted axis

as you can see, both misol and miist shifted, but the timing oscillations still persist.

looks like the next things I need to log are

mizsol
mizwmn
dmaufr
redist
etazaist

anybody have locations for them

I'm 99% on these. I would post these formatted for ME7L but it's late and I'm done for the night. I have the rest of %MDKOG if you see anything you need.

mizsol_w 0x382952
mibas_w 0x382968
misolv_w 0x38294E
misol_w 0x00F9BC
miszul_w 0x3829EC
mizsolv_w 0x382950
dmzms_w 0x382944
B_zwnget 0x00FDA4 0x0008
B_zwvzvb 0x00FDA4 0x0040
B_zwvz 0x00FDA4 0x0020
B_zwget 0x00FDA4 0x0004

awesome thanks, i will log those time permitting.

could use units and scaling though

doesn't have to be ME7L format, I can take care of that part.

I can post the scaling info when I get home tonight. All of the torque variables are the same though, so you can just copy from one of the ones output by ME7Info (i.e. mifa_w).

Log what I posted above as well as:

B_mibeg
miszul_w
mifa_w
misol_w
migs_w

This should cover everything that can trigger ignition angle intervention from torque and we can work back from there to find the source.

The intervention is triggered in %MDKOG and released in %MDZW.

Its starting to look like my MAF is reading too high. My actual load is too high for these boost levels.

I will have to scale back the MAF a bit...

Question:

Is KFMIRL pre-LDRXN used anywhere?

In other words, does changing KFMIRL values such that they are higher than LDRXN limits have an effect on torque monitoring?

If you can't get to it (because of LDRXN), how would it have an effect on torque monitoring?

Scaled back MAF does nothing.

Issue is definitely dmaufr/mizsol related...

so i need locations for

dmaufr
mizsol (got it)
mizul

dmaufr comes from:
misol (got it)
mibas (got it)
mizsol (got it)

mizsol comes from:
min(mizsolv, miszul) (got them)

mizsolv comes from:
etazwb (from ETADZW, which gets zopt-zwbas)
mibas (got it)
dmllr (idle regulation, probably not it)
dmar (anti judder) **** ETA THIS IS IT ****

miszul (got it, not it) comes from:
mizufil, mizuofil

mizulfil comes from:
mizufil, mdverbzu

anybody have the rest of those locations?

I'm assuming all of the mizu variables are 99% (looking at the maps, at >60% throttle position, they are all maxed), which probably means dmaufr or mizsolv is the culprit) ETA: i have miszul logged, and it is solid 99 as expected.

my car is busted so I haven't been able to log, so I'm just gathering info for when my car gets put back together

here is what I have on deck:
