Title: ARMD - antirukelfunktion and timing oscillations Post by: nyet on April 12, 2012, 01:07:14 PM 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 :( wkrdy and zaldy are both solid zero. miist is well below misol etazws shows A LOT of activity (http://nyet.org/cars/logs/typical_20120412_124024-timing-oscillations.png) Title: ARMD - antirukelfunktion and timing oscillations Post by: nyet on April 12, 2012, 02:28:13 PM 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 :) (http://nyet.org/cars/logs/typical_20120412_124024-misol-etazws.png) Title: ARMD - antirukelfunktion and timing oscillations Post by: Rick on April 12, 2012, 02:31:16 PM 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? Rick Title: ARMD - antirukelfunktion and timing oscillations Post by: nyet on April 12, 2012, 05:03:45 PM yes, n75, slightly underscaled maf
Title: ARMD - antirukelfunktion and timing oscillations Post by: nyet on April 12, 2012, 05:08:25 PM 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? Title: ARMD - antirukelfunktion and timing oscillations Post by: nyet on April 12, 2012, 05:27:33 PM disregard. misol has NO effect on this, nor does playing with IOP.
IOP does not appear to be the source of these oscillations Title: ARMD - antirukelfunktion and timing oscillations Post by: nyet on April 12, 2012, 05:39:15 PM Ok i made two files
one with IOP maxed (99) for 3000rpm+ and 191load+ the other with stock iop with ONLY shifted axis (http://nyet.org/cars/logs/iop-99_vs_iop-stock.png) as you can see, both misol and miist shifted, but the timing oscillations still persist. Title: ARMD - antirukelfunktion and timing oscillations Post by: nyet on April 12, 2012, 10:37:29 PM looks like the next things I need to log are
mizsol mizwmn dmaufr redist etazaist anybody have locations for them :) Title: ARMD - antirukelfunktion and timing oscillations Post by: phila_dot on April 13, 2012, 12:12:16 AM I'm 99% on these.

Title: ARMD - antirukelfunktion and timing oscillations Post by: phila_dot on April 13, 2012, 07:22:26 AM 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. Title: ARMD - antirukelfunktion and timing oscillations Post by: nyet on April 13, 2012, 08:57:04 AM 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... Title: ARMD - antirukelfunktion and timing oscillations Post by: nyet on April 26, 2012, 03:25:58 PM 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? Title: ARMD - antirukelfunktion and timing oscillations Post by: Gonzo on April 26, 2012, 04:40:02 PM 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?Title: ARMD - antirukelfunktion and timing oscillations Post by: nyet on April 29, 2012, 06:16:27 PM 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: Code: dzws , {} , 0x380D95, 1, 0x0000, {°KW} , 1, 0, 0.75, 0, {}Title: ARMD - antirukelfunktion and timing oscillations Post by: phila_dot on April 29, 2012, 07:26:38 PM dmaufr_w 0x382E7A

Title: ARMD - antirukelfunktion and timing oscillations Post by: nyet on April 29, 2012, 09:38:06 PM 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. Title: ARMD - antirukelfunktion and timing oscillations Post by: phila_dot on April 29, 2012, 10:28:51 PM 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. Title: ARMD - antirukelfunktion and timing oscillations Post by: nyet on April 29, 2012, 10:46:24 PM 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? Title: ARMD - antirukelfunktion and timing oscillations Post by: nyet on May 02, 2012, 06:06:02 PM 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. Title: ARMD - antirukelfunktion and timing oscillations Post by: nyet on May 02, 2012, 06:26:58 PM AHA. no wonder i'm seeing it on the dyno.. not enough load.

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.

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. Title: ARMD - antirukelfunktion and timing oscillations Post by: nyet on May 04, 2012, 09:01:26 AM to which maps are you referring? 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 Title: Re: ARMD - antirukelfunktion and timing oscillations Post by: nyet on May 04, 2012, 10:03:28 AM I have split this thread from here

Nice work dude! Title: Re: ARMD - antirukelfunktion and timing oscillations Post by: nyet on May 05, 2012, 04:42:13 PM actually, maybe not. im still seeing some AR for some reason and i dont know why
stay tuned Title: Re: ARMD - antirukelfunktion and timing oscillations Post by: nyet on May 05, 2012, 05:09:07 PM Yea. I had to disable it completely by maxing KFDMDADP and KFDMDARO
It will have to stay that way until i can log the other ARMD variables (mkar and nmod in particular) Title: Re: ARMD - antirukelfunktion and timing oscillations Post by: nyet on May 05, 2012, 07:34:37 PM Just broke 400whp on 91 oct, 85F IATs
ARMD is totally disabled. I can't figure out how to properly tune it out, so it stays off (for now) I'm happy where the car is for now; need to drive it around and clean up FTs anyway (just went to EV14 @ 3bar) Title: Re: ARMD - antirukelfunktion and timing oscillations Post by: Snow Trooper on May 05, 2012, 08:02:19 PM Summary on steps to do a basic kill for the adventurers here?

KFDMDARO 0x1de7c 8x6 16 bit all FF's in KFDMDARO for the cheesy fix. I have KFDMDADP also ff'd out but probably shouldn't I expect the REAL fix will be in KIFZGHG, but i won't be able to tell for sure until i get a few ram locations and log (PLEASE tony/setzi/phila help me out!) i'll have an updated xdf/kp soon. Title: Re: ARMD - antirukelfunktion and timing oscillations Post by: Rick on May 06, 2012, 07:31:48 AM Was zwout following zwbas or zwsol with ARMD intervention?
Title: Re: ARMD - antirukelfunktion and timing oscillations Post by: nyet on May 06, 2012, 09:55:24 AM mostly zwsol (except when zwbas < zwsol, which is only occasionally)
are you saying i should try to get zwsol up? ARMD is causing zwsol to fall far below zwbas Title: Re: ARMD - antirukelfunktion and timing oscillations Post by: nyet on May 06, 2012, 10:02:12 AM I'm thinking if i bring nmod up high enough with KIFZGHG it should send zwsol over zwbas
Title: Re: ARMD - antirukelfunktion and timing oscillations Post by: s5fourdoor on May 06, 2012, 03:40:45 PM I'm thinking if i bring nmod up high enough with KIFZGHG it should send zwsol over zwbas word. its nice to see this being solved. could you possibly post tunerpro screenshots of everything necessary to add this to the XDF. there's a good bit of stuff I've added to one of your old XDF's that I should probably send you for the sake of merging. Title: Re: ARMD - antirukelfunktion and timing oscillations Post by: nyet on May 06, 2012, 04:44:53 PM i will once i actually have information that i know is right. most of what I have so far is pure speculation
Title: Re: ARMD - antirukelfunktion and timing oscillations Post by: Snow Trooper on May 06, 2012, 04:57:30 PM Thanks nye, I will do this tonight and post screen shots of everything for the basic kill. Had a successful night out last night with logging and all that.
Title: Re: ARMD - antirukelfunktion and timing oscillations Post by: nyet on May 06, 2012, 05:47:54 PM I think setting KFDMDADP to all ff's is probably unecessary. i think you want to preserve dashpot judder damping.
i THINK this is whats CWARMD does: bit 0 determines if the clutch state should be allowed to halt AR and re-initialize the rpm model. Stock is enabled bit 1 determines if the clutch state should be filtered for this re-initialization. If 0, it is unfiltered. If 1, the rpm state has to go from not increasing to increasing (B_tpnmot), or increasing to not increasing (B_thpmot) for a certain amount of time before the clutch counts as "not pressed" after being "not pressed". Stock is disabled. bit 3 allows B_dash to allow B_in to turn on B_tvars for TVARS time. Setting bit 2 to zero is probably equivalent to setting KFDMDARO to all ff Setting bit 3 to zero is probably equivalent to setting KFDMDADP to all ff bit 2 allows B_lsd to extend AR by TVARS after B_in goes inactive. Stock is enabled in the g-box i have. I do not know the m-box location. bit 3 allows B_dash to extend AR by TVARS after B_in goes inactive. Stock is enabled in the g-box i have. I do not know the m-box location. Title: Re: ARMD - antirukelfunktion and timing oscillations Post by: nyet on May 06, 2012, 06:21:03 PM The simplest total kill is probably to set TMAR to something really, really big - AR only enabled if engine temp is higher
RPM based kill can be done via: raising NARLLA (based on gear) - AR only enabled if RPM is higher or raising NARASTG and/or lowering NARAO - AR only enabled for RPMs between this range however, this also kills dashpot AR, which you probably dont want to do. I think the best quick and dirty kill (until i figure out otherwise) is to ff KFDMDARO the question remains though, should ARMD be disabled? I got more power when I did, but what is the tradeoff? Title: Re: ARMD - antirukelfunktion and timing oscillations Post by: Snow Trooper on May 06, 2012, 09:42:29 PM I am hesitant to try it on crap fuel.
Title: Re: ARMD - antirukelfunktion and timing oscillations Post by: nyet on May 06, 2012, 10:01:15 PM I don't think there is any real danger
Title: Re: ARMD - antirukelfunktion and timing oscillations Post by: Snow Trooper on May 06, 2012, 10:44:05 PM What in your opinion is the best method for killing it. If I understand correctly we are killing numerous other things also.
I will admit I feel foggy on this subject. I do indeed experience the bouncing timing at times. Title: Re: ARMD - antirukelfunktion and timing oscillations Post by: silentbob on May 06, 2012, 10:55:13 PM The simplest total kill is probably to set TMAR to something really, really big - AR only enabled if engine temp is higher RPM based kill can be done via: raising NARLLA (based on gear) - AR only enabled if RPM is higher or raising NARASTG and/or lowering NARAO - AR only enabled for RPMs between this range however, this also kills dashpot AR, which you probably dont want to do. I think the best quick and dirty kill (until i figure out otherwise) is to ff KFDMDARO the question remains though, should ARMD be disabled? I got more power when I did, but what is the tradeoff? The tradeoff is that the car will drive very bumpy if you turn off all the driveability functions. It's really anoying especially in city traffic. Calibrated right it will not influence power in any way. Even "minor changes" like different engine/drivetrain mounts can have the effect that this has to be changed. That's also the main reason why the RS4 values are so different ;) Title: Re: ARMD - antirukelfunktion and timing oscillations Post by: Snow Trooper on May 06, 2012, 11:06:56 PM Thanks bob! So in essence you agree that the only real draw backs are drivability and such? For a kill/drag file people can do without?
Title: Re: ARMD - antirukelfunktion and timing oscillations Post by: silentbob on May 06, 2012, 11:24:03 PM ARMD, SAWE, DASHPOD and LSD are the factors to influence the driveability/responsiveness/smoothness of the car.
If you need it only for drag racing you can turn them all off. Just try what works better for you. Title: Re: ARMD - antirukelfunktion and timing oscillations Post by: nyet on May 06, 2012, 11:27:36 PM What in your opinion is the best method for killing it. For now, just 0xFFFF all of KFDMDARO That will leave dashpot ARMD intact. Title: Re: ARMD - antirukelfunktion and timing oscillations Post by: nyet on May 07, 2012, 10:00:10 AM For now, just 0xFFFF all of KFDMDARO That will leave dashpot ARMD intact. In theory, MAYBE only the last row in KFMDMDARO, but i haven't tested it. need to log mkar_w Title: Re: ARMD - antirukelfunktion and timing oscillations Post by: Vitruvian Engineering on May 07, 2012, 07:33:40 PM Just thinking out loud here, but do you think that this ARMD might possibly cause timing oscillations even at low load/RPM? For example, trying to track down a different issue, I made a file where the only things I switched from stock were my MAF/Fuel injector stuff, and though my parking lot behavior is by no means terrible, there is still some slight juttering (even with stock KFMIRL/IOP, etc). I've got harder stern mounts all around, do you think it's possible that ARMD oscillations affect that low range at all?
EDIT: Sorry, this is jibberjive. I forgot to sign out of this account. Title: Re: ARMD - antirukelfunktion and timing oscillations Post by: nyet on May 07, 2012, 08:06:25 PM ARMD is supposed to smooth out those felt vibrations at low rpm, so yes, it absolutely could be active. In fact, it is designed to ALWAYS be active; there are very few situations where it is disabled.
However, if not properly calibrated, I could see that ARMD might make felt vibration worse. In my case, I cannot feel the vibrations; they only show up in logs and rob the car of HP at wot. Title: Re: ARMD - antirukelfunktion and timing oscillations Post by: Snow Trooper on May 08, 2012, 01:40:47 PM Same as you nye.

If you need it only for drag racing you can turn them all off. Just try what works better for you. silentbob, what are these functions SAWE, LSD, DASHPOD? I couldn't find these functions in my funktiosnrahmen file.... ARMD I have disabled, but want to turn off all these other functions... P.S> Those are all "comfort" functions? Are there any more that could intervene with torque limited by kfmirl (ldrxn) and kfmiop? I'm looking for a way to simulate drive by cable behaviour... Title: Re: ARMD - antirukelfunktion and timing oscillations Post by: nyet on May 08, 2012, 03:56:56 PM Ok; mkar is what i thought it was (% torque at transmission), so to disable ARMD on wot, you only have to modify the last line of KFDMDARO... 0xffff is for sure kill, but i'm betting 0x8000 (50.00) is fine, since I believe thats how the RS4 disables ARMD at high torque/low gear.
So my DARO currently looks like this (rs4 and 50.00 on last row) Code: 1 2 3 4 5 6 I haven't tested it on the dyno yet (low load) but that should work. Also, have copied the RS4 KIFZGHG Code: 0 1 2 3 4 5 6 7 Title: Re: ARMD - antirukelfunktion and timing oscillations Post by: Snow Trooper on May 08, 2012, 04:43:42 PM What factor are you using? It doesn't really matter cause I just ffed the thing but it was annoying looking at it with weird values.
Did you notice most stuff around it is undefined and ffed? Wonder what is there ... Title: Re: ARMD - antirukelfunktion and timing oscillations Post by: nyet on May 08, 2012, 05:38:59 PM What factor are you using? hmm? not sure what you are referring to, sir.Title: Re: ARMD - antirukelfunktion and timing oscillations Post by: s5fourdoor on May 08, 2012, 06:28:30 PM what formulas are you using for these tables? i'm not seeing the values you posted at all... any idea what these axis represent?
Title: Re: ARMD - antirukelfunktion and timing oscillations Post by: nyet on May 08, 2012, 06:53:20 PM I didn't put in the mkar axis, only the gear axis.
I'm assuming you can figure out the axis data properly on your own (until i post a mappack) I use the f-box rs4 as a reference for the values, and the g-box s4 damos for a map reference. Title: Re: ARMD - antirukelfunktion and timing oscillations Post by: silentbob on May 08, 2012, 10:47:16 PM silentbob, what are these functions SAWE, LSD, DASHPOD?

Are there any more that could intervene with torque limited by kfmirl (ldrxn) and kfmiop? I'm looking for a way to simulate drive by cable behaviour... These functions all influence how torque is delivered in different dynamic stituations. It's all in MDFAW (page 605). SAWE = torque ramping when going into pull with fuel cutoff and when injection is enabled again LSD = torque ramping with positive load jump DASHPOD = torque ramping with negative load jump Theres also MDBG to limit the max torque gradient.

Thank you! So I'm trying to disable them all it this way: LSD: VLSD -> FF SAWE: NGFSAWE -> FF (not sure if this engine speed threshold should be 00 or FF though) DASHPOD: VDASH -> FF MDBGRG seems to be already disabled by default (VMIBGR -> FF) Title: Re: ARMD - antirukelfunktion and timing oscillations Post by: NOTORIOUS VR on May 10, 2012, 06:22:44 AM This is exciting! :)
Title: Re: ARMD - antirukelfunktion and timing oscillations Post by: julex on May 10, 2012, 07:15:34 AM Definitely. Maybe finally we can figure out to have really snappy engine instead of slow ramp up moderated by these functions.

Maybe finally we can figure out to have really snappy engine instead of slow ramp up moderated by these functions. IMO that is the biggest issue with running ME7 on more wild setups.

Even on pump 1-3 can be held back. Along these same lines we also need a real edl turn off, esp and so on. Obviously only for occasional fun.

As far as i can tell, there is no way to disable it in the ECU (only the fuse 42 trick). We have to get into the ABS controller.

it used for reporting the actual torque on the CAN bus (i think). in the gbox damos i have, its 101A3. i believe mbox is the same, but that is just a guess. Title: Re: ARMD - antirukelfunktion and timing oscillations Post by: berTTos on July 15, 2012, 03:48:09 PM Ok; mkar is what i thought it was (% torque at transmission), so to disable ARMD on wot, you only have to modify the last line of KFDMDARO... 0xffff is for sure kill, but i'm betting 0x8000 (50.00) is fine, since I believe thats how the RS4 disables ARMD at high torque/low gear. So my DARO currently looks like this (rs4 and 50.00 on last row) Code: 1 2 3 4 5 6 I haven't tested it on the dyno yet (low load) but that should work. Also, have copied the RS4 KIFZGHG Code: 0 1 2 3 4 5 6 7 Nye - thanks for this. these settings work wonderfully on a STG3 car with upgraded driveline mounts. i was experiencing some driveline vibration on decreasing loads, from time to time - and your suggested values have eliminated this occurance.

Being Volvo the function is a little different, but does follow the FR, although tans is in there too. This is what I'm seeing in my logs, not sure if it's ARMD or not at this stage. (http://i716.photobucket.com/albums/ww161/jpcurrie/v18.png) From looking at the FR and code it looks like if dmar_w > 0 then it will set the b_ar bit. I'll have to do some logging to verify.

Title: Re: ARMD - antirukelfunktion and timing oscillations Post by: julex on January 21, 2014, 06:46:35 AM I would call it normal timing oscillations...

I have problems with bad performance and timing going up and down especially on 2nd gear, this has also made for two burnt exhaust valve. I assume that the exhaust gas can be quite hot with timing around 0 on high revs and load. Problem is that I cannot seem to locate the KFDMDARO, NARAO, NARASTG or NARLLGA in the bin I´m using. If anybody has any suggestions on where to look I would very much appreciate the help. Car is Audi A4, 1.8t, Wideband, ME 7.5, 8E0909518AA 0004.Bin Also the rev limiter is bothering me, on locations 172A4, 172A6, 172AA and 172AC I have raised the limiter but still it does not have the desired affect.

Title: Re: ARMD - antirukelfunktion and timing oscillations Post by: Blazius on September 05, 2019, 10:32:14 AM Anyway disabling ARMD is not half a bad idea... many european tuners and big companies do this, since not even Audi/VW/VAG technicians bothered to set it up right, in some cases the maps are copy pasted from one version to another , as far as I heard.

Looking forward to logging these variables and deducing the data. Title: Re: ARMD - antirukelfunktion and timing oscillations Post by: kruftindustries on February 21, 2022, 04:00:36 AM In my car, setting the last row of KFDMDAROS to 50 and leaving KFDMDARO alone caused dmar_w to stay at 0 across the load range. I have double checked the disassembly and it doesn't appear I mapped them incorrectly. Did I in fact label them incorrectly, is this expected behavior and the wiki needs an update, is it different for some ecu's?
Title: Re: ARMD - antirukelfunktion and timing oscillations Post by: prj on February 21, 2022, 04:11:39 AM Just editing the last row is usually fine.
Turning it off completely I don't recommend, there is noticeable bucking behavior at low load that completely disappears with this function being active.

Turning it off completely I don't recommend, there is noticeable bucking behavior at low load that completely disappears with this function being active. 2nd. Do not fully disable ARMD unless you really like the race car experience. Note that the A4/S4 does not have a race car transmission/flywheel/gearing/suspension/steering etc. so you'll probably regret it even for a "race care" experience. Title: Re: ARMD - antirukelfunktion and timing oscillations Post by: kruftindustries on February 22, 2022, 06:49:43 AM By "across the load range" I meant mkar_w > 43, it works as expected but I modified the "stationary" map KFDMDAROS. Increasing last column of KFDMDARO didn't reduce the timing intervention. Just reporting results from the field and making sure I didn't label the maps backwards.

Maybe someone has an idea, it could be ARMD intervention?

Added B_ar to my log, and =1 all the way during pull. If i understand corectly, armd active? But DARO last rows set to 100 in this log. Need to mention, that may car VW Sharan with S3 ecu (extra 600-700kg, absolutely diverent drivetrain, and finally stroked engine). Maybe i shoult disable armd completely via TMAR?Title: Re: ARMD - antirukelfunktion and timing oscillations Post by: TeknoFi on October 09, 2022, 04:38:00 PM What kind of value your TMAR have as stock? Looking for confirmation for that address ...
Although in the meantime I think I will use and maybe also permanently NARAO 1600rpm, it works fine for me to get rid of most timing retards. I can recommend it, as pulling feels really smooth. The standard upper limit was 7200rpm. |
