The BMW part number read by Ediabas is 7591972, but Realoem doesn't find anything under that. It shows part number 24007590129 for my VIN which is a GA6HP26Z.
Very strange. More research is needed.

FWIW my 2010 (09/09 build) shows the same HW number. I would guess that HW number refers to the tcu rather than the trans as a whole.

Today, I successfully flashed the ZB 7595728 with cal 7595729 with WinKFP . There were a bunch of DTCs afterwards but cleared fine. However, the driving experience wasn't that much different. If it all, the shift points are now later (around 2400 rpms). I took some data today which I'll post soon but intend to let the cleared adaptions settle down a bit and then take more data.

Interesting. When I flashed to the 7606274 software a couple months ago I noticed a definite difference in the tc lockup for gears 2 and 3, but nothing else seemed to be different. I have to wonder if the A7609647 file would work even though it's shown as an n57 file. Was the n57 ever available with a 6 speed? It doesn't seem possible for the hw version to be the same between 6 and 8 speed transmissions

In Ediabas, select SGBD GS19D and double click job "steuern_adaptionswerte_ruecksetzen".

What SW/ZB did you have before? My original ZB is 7606274. Would you mind looking up and posting your UIF (user info field)? Mine looks like this now.

That is in fact interesting. What car was the N57 in?

I guess you're right. I didn't notice that the BMW part number matches the HW number. That's definitely the Bosch EGS only.

Not sure why, but in EDIABAS my uif doesn't show jack. It's all words and no numbers. I'm sure I'm doing something wrong but I can't imagine what, I'm running the gs19d program and then the job you posted earlier. I'm not near the car right now so I can't post the exact output.

In the US other than the f10 535d I'm not sure what the n57 came in. Probably the x5d starting in 2012. In Europe I think it's in the 330d and 335d in different variations after 2011.

I don't think we can read the UIF in Ediabas, just the AIF. I read the UIF with WinKFP after the flash under Special. Not sure if that can be read without flashing.

[Mik325tds]

Here is the first data comparison between the original SW and the 7595729 calibration. This shows how difficult it is to even get two similar runs with defined input. I think we need a hack that simulates a skinny pedal and can give exactly 30% throttle for 7 seconds or so.
I wonder how someone can state that the tranny seems to behave different in any way just using the butt dyno.

Yes, yes, yes! First critical milestone achieved!

Mik, I think I can set 30% throttle with some external electronic intervention.
Have a trick or two up my sleeve to sync the data between two datalogs. And on another front, Pheno may have found a method to speed up the datalogs in TestO. I'll be testing that out tomorrow.

Many things are coming together quickly, wow.
Hooper, thanks for contributing. We can use all the help we can get

[Yozh]

This is awesome. Thanks for having the courage to even try it out.

[Len_Beach]

The N57 came in the 330d LCI. This showed quite a leap in performance and economy over the pre-LCI 330d with the M57.

Some info here;
http://www.bmwheaven.com/database/show.php?id=952

Realoem shows that my car also has the GA6HP26Z gearbox.

Let me know if there's anything I can do to help the cause

Interesting stuff. Was wondering if Pheno has the ability to write something to send the dde a command through Testo for throttle input. Would probably be highly dangerous ☺ but good for testing what you guys are after.

[Hoooper]

Im going to send the string off to a couple groups I know are pretty good with coding, hopefully they can give some thoughts on the code and how we should be looking at it. Im not doing anything myself as far as code editing goes, I think this is well beyond my beginners C++ knowledge . It sounds like we have a couple guys pretty experienced with code in here but I figure the more eyes the better, hopefully we can get a little helpful feedback.

Here is a document that I think explains the progression of these transmissions:

[Hoooper]

So Im looking in the GKE195 folder again and I noticed the file "7591972A" which happens to be the same number as the HW number indicated for my tcu. I opened up the file and this is the first few lines:

;============================================
;Austausch-Datei Programm
;============================================
;
;;ZL_System: GS19.11.0
;;ZL_Projekt: FM
;;ZL_Referenz: 0479S90T641Z
;
;============================================
;Freigabe: BMW
;============================================
;
;;K_Stand: 22.04.2008
;;K_File-Name: 7591972A.0pa
;
;;Fahrzeugidentifikation
;;K_F1 Grundprogramm fuer GS19.11
;;K_F2 6HP26TÜ/32TÜ

Grundprogramm translates to basic program, so basic program for GS19.11. Any significance to this? The rest of the file after all the description lines is the same hex code nonsense that the other files have. The general consensus im finding is that all that hex code is basically just reference chart data which would be pretty tough to make use of without having a whole lot of data for comparison. If anyone could find the program that provides the structure for all this data it could be a lot more useful.

[Mik325tds]

I came close to calling one of the phone numbers in these files... I find it amazing that they do list them.
So the 7591972A.0pa holds the program (algorithms) for our transmission while the SW files hold the calibrations - very strange. Why not call it the way it is (SW = SW, Cal=Cal, HW = HW instead of HW=SW, SW=CAL)?
Driving the 7595728,0000000,7591972,A,7595729DA,0FFFFFFFFFD,00 0,1 B - combination didn't reveal anything new. Very little difference in shift behavior. DWR confirmed this morning that comparing the two files didn't show much changes within the potential 150 maps.
I guess I'm on the next combination. Any preferences?

[Hoooper]

Not sure which one to try next. Based on Len Beach's response above I wouldnt try the ones for the N57. Which daten pack are you getting the files from? The latest is V55 but I wonder if there was a previous version which included a file that has since been removed from the pack.

Funny you say that, I was looking at them yesterday and thinking what we should really be doing is hiring this Sergiy Pogrebnoy character to do a little side job for us

[Hoooper]

Just downloaded the most recent daten and it has a "new" file in it under the GKE195 folder and it says its for M57 Maybe worth a try, I did not have this file before this update, but its not even as new as the 7606274 so not sure what the deal is. Maybe what you should be doing is comparing it to a file you know is different like the file for the B3 or any file for the 335i (GKE215 I think?)

Oh man, if we could get our hands on a calibration template to know what is what. Even in German would be great - right Mik? OK Hoooper, you're in charge of donations for the consultant, ha! I'm laughing now, but that could change...

Thanks Hooper for supporting the cause like that!
Would be glad to try it. Would you mind zipping the .ats, .dat, .his and .hwh files and posting or sending them to me?
