By the way 'aus' means off AFAIK.

Alright as promised...

SDS hooked up to my car:



Now let's take a look at the current stored adaptations.. last time I reset my adaptations was about a month ago.

1 - 2 Shift



2 - 3 Shift



3 - 4 Shift



4 - 5 Shift

Oxygen

Okay now let's reset all of the adaptations and see what the values look like..





Everything is squared out to ZERO for the most part..

Oxygen

So my thinking was as follows.. if you think you found the magical option to stop the ETC from adapting to your driving, and you enable it and reset your adaptations, after driving the car for sometime the adaptation values should remain at 0 correct?

Well, next step was to go into Developer Mode and access the variant coding in the ECU.

On my car the option was #251 and worded slightly different, but I am running the M275 motor, so that's expected...

I noticed the drop down has two options:

Motor-Code E/A 2, AAD (Adaptive Antriebsdynamik) aus
Motor-Code E/A 2, AAD (Adaptive Antriebsdynamik) ein

My rudimentary knowledge of German tells me that "aus" means out or off and ein means enabled or on.

By default, the setting was on aus so that Adaptive blahblah is turned off by default, so it's not what you think it was...

Myth busted.. tune in next week!

Jeez smart guys SUK! J/K great info keep it coming!

Awsome contribution Oxygen.
Ladies and gentlemen, that is forum sharing done RIGHT!!!

Hope this helps find the key to adaptation deletion.

Oxygen, that was a very well put together and well-organized post with very nice pictures and great information; thanks for sharing

However, now that we know that this setting has nothing to do with tranny adaptations, the question still remains: what the heck is drive dynamics adaptations? What does it affect and to what extent?

zoink

Hold on... pardon my slow brain.

So what you're saying is.... by default the adaptive blah blah blah is turned off ("aus"), yet, the car still applies adaptation to our driving?

Hmmmm..... could you try the following?
Set to "ein", reset adaptation, drive the car and check adaptation value again as well as the adaptive blah blah blah value (whether it stays "ein" or goes back to "aus").

The reason is.... if our cars have adaptation feature on by default, it should be reflected somewhere. Our guess is this adaptive blah blah blah... and it's set to "aus" by default. If our guess is correct, we just need to change to the other value. If this is the case, it may be the MB software engineers drank too much beer so they flipped the value

May be I oversimplify things, but this adaptation feature should be a big chunk of codes in the entire software.... why haven't any tuners been able to identify and figure out how to "skip" this part of codes?

Well just got out to mess with it and literally ALL of my boxes showed up blank. Must be the aftermarket tune.

HOWEVER when I clicked on the boxes, it did give me the option of shutting it off or on so I gave it a shot and we'll see what happens. Claims it wrote the info back to the ECU and car does start so we'll see.

I have another ECU with a different tune, gonna try that as well.

Maybe this will only work with stockers?

Still gonna keep trying. Myth on my end still listed as plausible.

Oxygen

The ECU and TCU in my car are both very far from being "stockers".. If you have blank fields/data missing that's not a good thing or a sing of a tune.. Either your ECU is not coded right or your SDS is no good.

Jakpro1

Maybe my Star is having trouble, but my tune is a custom dyno'd LET and she works like a charm. Best tune I have ever had hands down.

Will right up more on it when I get time.

I have 3 ECU's and 2 TCU's now so I'll have some fun messing around with them and see what she does.

Interesting read

Oxygen

Yes, exactly what I said above but the short version. The option is set to "aus" by default. Clearing adaptations and driving again changes the values.

I appreciate you setting my rocket ship up to be the test vehicle or "werkswagon" as our frands int Stuttgart call it.

Thanks to Jakpro and Oxygen for pushing the envelope and telling us about it.

Dogshine

can you drive it, then check values, then do sneaky ecu reset and then check values again and see what happens?!!?!

Jakpro1

Oxygen my brotha, when you're right you're right and you called it.

After tinkering with this ECU for quite awhile I swapped it out for another one and it pulled up the menu just fine.

This ECU that was malfuctioning was the one that "the Devil with a tuning kit" last touched. (not VRP and for sure not LET...you guys know who). Let's call him "The Tuner Whose Name Shall Not Be Mentioned" in our Mercedes Village. She never worked right but seemed to be back to normal after the LET flash.

Just amazing that the LET tune took on that ECU. Actually works great but maybe she was just damaged by Lucifer more than I thought.

Anyway, got the menu to pull up but she would not write the settings to ECU. Gonna keep messing but unless Mr TT can shed some insight , not sure how much more I can do.

+ 1 hate adaptations

Figure it out guys! You know the new E63's(and all SL63) w/ the 7sp dual clutch have whats called sport sharp "S+" which doesn't take adaptations. But not us

Link to sneaky ECU reset again please.

Oxygen

Yes... reset adaptations with SDS, make sure the values are zero'd out, drive it for about 30 minutes, check the values again, they should start accumulating, then do the "sneaky ECU reset" with the key and gas pedal and see if that actually clears out the adaptations the same way that SDS does... good idea I'll give that a shot.

MB_Forever

That is very interesting........ this will prove 100% whether it works or not. I'd love to see this tested on a 63 as well

Oxygen

Alright I'll test it on a 63 also.

MB_Forever

That's be awesome I used to feel a noticeable difference when I tried it on my C32, but I was never able to duplicate that same difference on a 63, so I always thought that it either didn't work or they changed the codes.

Thank you, I really appreciate you taking the time and trying that

intellilogic

I like my comfort mod all nice and adapted (I think, I don't remember how it was when I first got the car, I went every in sports mode, on it all the time hahaha)

I just wish sport wasn't adaptive, they fixed it in all the new cars with the S+ - but I don't have one of those cars... =[

Dsmed

Hey Oxygen, screen shots that you have up are not for the adaptive shift of the trans. Those values are for tcu adaptations to compensate for clutch wear, solenoid actuation speed etc.

High fill and response times indicate worn trans components, but has nothing to do with driving adaptations.
