Interesting Stats for DCT

[aboulfad]

This car logs so much info it is insane Though not sure how it classifies "smokie burnouts", I have never done nor know how, and it reports my car did 8! Race Start is LaunchControl and I did only one. Those smart german engineers even added a log for wear data erasure...

PS: check post #15 for seat stats :-)

Really cool info.

Another observation: it's cute when piggyback owners state BMW can't determine if the car had a tune on it when the device is removed.

post some more data

The amount of data logging that this car logs and is sent to BMW upon hooking up ISTA/D is dizzying (FASTA)... I've counted around 925 jobs for just DME, that queries just about everything! Edit: There is a DME Tamper Fault that is raised http://f80.bimmerpost.com/forums/sho...4&postcount=40

I've found some mysterious data blocks (TripRecorder) that have no or little explanation... yes, big brother is watching us and logs even the key presses in our cars! (why would they log how many times I pressed the M1/M2 button )

Like what? There is so much technical parameters that I have no clue what they do... suggest it and I'll try to locate it. To give an idea, check the attached text file which are the results template for one argument DKG_ISTWERTE... (actual values of DCT gearbox )

Smokie burnout...lol.. That is subjective. Very interesting. We always knew really that they logged everything, people just didn't want to believe it.

Sub'd as this is awesome.

Its so funny that even in Deutsch its called "smokie burnouts". Though still don't understand the parameters to consider you have done a smokie burnout.

My tires on few occasions did spin but with DSC on, the car didn't move... I wonder if it considers tire rotation but no vehicle motion as smokie burnout, but with DSC on, it's just an "embarrassing burnout"

Thanks Cary ! although this is it, unless someone is looking for some other stats or data that I can dig up.

I think smokie burnout mode is when you floor it in S3 with DSC off from a stop and it revs up slightly and does a clutch drop.

I think you described how to do a smokie burnout. I never drive in S3/DSC Off and the only time I used that combo was my failed attempts for LC where car/tires didn't spin or move so it is still unclear what conditions count as "smokie burnout" as reported by the stats.

Haha. Well if you mash the gas with DSC on, does it still rev up a little and do a clutch drop? My thought is that rev-up+clutch drop action is the smokey burnout "launch" vs a launch control "launch".

In this article, they say you do what I am describing in conjunction with the brakes to do a smokey burnout?

Fascinating stuff for what they are trying to log and track.

Do they log how many times one is adjusting their seat positions too?

Interesting read , but its confusing, as they indicate its an optional feature !!! So it may be possible when I unsuccessfully did LC, that it somewhat logged as smokie burnout but the car/tire not moving, weird...

When DSC is on and I am in S2, the few times I mash the pedal aggressively but not all the way, my PSS just studder in place. (I obviously learned Aggressive pedal movement and DSC dont play nice)

I'll check and report back ! My passenger likes their a$$ toasty Driver SLV is high as I have easy entry/exit !
The stats are not pulled automatically in my FASTA session, i executed the jobs manually. Maybe BMW doesnt care about seats

have you figured out a way to erase/reset this FASTA data?

[TurboSid]

Wow really cool info. Subd

Oh ! Now we are getting serious there are tool32 jobs to erase some, but there are routines to log that you erased stats like the above DCT wear data. To erase the latter probably requires some good investigative work and I don't have any tools to explore further.

FASTA data is data from many ECUs...The location of the various ECUs stat data and other "interesting" data is unknown to me, wether it resides in each ECU uC/Flash or rather collected in a central embedded FLASH storage so it survives flashes/erasure and then retrieved via FASTA service... I know that the FASTA routines queries almost every ECU for lots of data but it's too easy to assume that every ECU stores it's non volatile info, or maybe it does and then it becomes more difficult to erase data on dozens of ECUs...

I can devise few experiments to find out more, but my current goal is information search only !
PS: the guy that speaks base64 probably knows this stuff

There is Fart detection sensor in the seat and data send in real time to NSA

[dzvero]

Its cool , do you have steps to retrieve these data? I want to know what previous owner did to my car

The sensor on mine is probably crooked by now if there is one

Folk seem surprised but it seems fairly obvious as to why a lot of the data capture routines are in there. These data are invaluable real world feedback on wear and tear items in respect actual use and all sorts of biometric insight into what functions are used vs hardly used and as it applies again to design, layout and functionality in a car - so whilst it may appear obtuse to some as to why certain data are collected, I have no doubt just about every aspect of engineering and user interaction is being tabulated and analyzed to effect future design.
