Discussion about issues encountered whilst converting to M3 Flash and GWS

What do we all think this - It may be time to do a re-learn on the clutches. Im reticent in advising that though. It may have been a contributing factor this whole time. Should we engage a clutch subject matter expert at this point ?
I brought that up a while ago because it seems like the clutches need to be 'relearned' by the EGS module? https://bmw.spoolstreet.com/threads...ng-to-m3-flash-and-gws.3011/page-3#post-35674
Wonder if that's part of the problem, just like you. Seems like the system doesn't know how to interact with the clutches. When I had the GWS installed I did *NOT* try to shift at WOT, only with partial throttle.
Yes i did , 3 4 5 full throttle
one time after continuous pulls donig logs for ken the transmission overheated
Also with regular cruise and acc if they don't work there is a trick / work around that will fix it.
Basically you recode everything with no cruise at all, this will store all the default value needed for it but not be active. After that you and the cruise functions to the vo and and make the adjustments via notodata coding only, this will fix cruise and acc if you have it. I've only seen this on one case buying worked a treat.

The teach- in procedure triggered something for me. This pdf calls put all the reasons for resetting the mdct. Start on page 52.
This is similar to my current scenario. I have an M6 kombi in my 535 so I can get the oil pressure gauge and pretty colors. I got the oil pressure to show correctly, etc but the cruise control has never worked. I get a can error from the DCT if I remember correctly.
Man, this is exactly what I thought needed to be done when I originally performed the GWS swap-over. We were all concerned with premature clutch wear due to adaptation reset. I didn't have ISTA/P installed so I couldn't easily perform the steps. Reverted GWS to be on safe side.
What does the M3 DSC provide at this point? Is it required for MDM or to use MDCT?
I've read this PDF before but didn't think to check those pages. Great to bring this back up! The PDF also mentions torque intervention:
The tech jobs:
I really hope this is just a learning problem... Our fear of prematurely wearing out the clutches has caused us to induce slippage, which has prematurely worn out the clutches.

That’s the hypothesis but it needs to be tested. @dyezak might be able to try. What if it’s not that though ? Aside from final drive could it be anything else ?
Then you will bring your car to me and il do it all while you record
Happy to volunteer my car for experimentation as long as it can be drivable within a day or so but for a permanent install I don’t have the money to get it all done.... not yet anyway
What software do I use to do the relearn procedures, they were all grayed out in ista/rhinegold, what am I doing wrong lol
You need to do a full vehicle test before you can run any of the procedures.
well shit. i feel stupid now lmao.
do i need to do this as a 335is or an m3 or does it matter?
You don't know what you don't know brother.
Nah it should not matter. Ista will use the VO from the CAS for identity not the nfrm, but I think think it will matter. I usually go on 335 since it suits the box.
