Will this flash be applicable for the 335i? I have a 12/2006 E90 that won't accept the Alpina B3 flash but I would like to change the characteristics if possible without spending £££ on a tuner flash if possible.

3lli0t - you're awesome!
It works!
I changed this line from
:1001300000000000000000000000000000000000BF
to
:10013000000000000000000FF000000000000000BF
Old checksum was
$CHECKSUMME 571E U

Used NCS dummy to read the file. It said that the checksum doesn't match and if I'd like to update it. YESSSS!!!
:10013000000000000000000FF000000000000000C0
$CHECKSUMME B1C8 X
How much more convenient can it be?

We are now ready to flash updated cal files to our EGS!

Yes, please. I'd like to hear your opinion on it.

Do you know which transmission and SW you have?

Hi,

here are the details:

EGS: ZB7606259

VIN:WBAVB72090KM95483

When attempting to Flash with B3 ZB number:

Error 201:

Check hardware number

Wrong ECU hardware number: 7566894 (BSU not possible)

I don't know the transmission part number but I can find out.

Exciting stuff guys. Just outstanding.

Sorry mate. Doesn't look like it is compatible. You got the GKE215 family while we are working on the GKE195 family. However, you may apply the same strategy of finding the maps and modifying them yourself.
You should try flashing some updated and older cal files first to see if you find some obvious differences. Your compatible ZBnumbers are:
7574812
7606261
7606257
7606255

I just made sure that 3lliOt has the highest ratio of rep points to posts on this forum!

Another milestone down

Although, he will have some work to do to keep up with you, MIK325tds!

Thanks for the reply.

Can I use any of those ZB numbers on my transmission and is the current number the latest version?

Thanks

Is there anything i can provide to determine whether UK trannys are the same as US ones?

Mik325tds, there are 10 shift maps in the same section of the cal file. There may be others elsewhere, I just have not been able to confirm that. Out of the 10, 4 look promising. See image below. Please excuse the x-axis scale. The cal file data must be convertered to get the scaling and there is slight differences between maps - doing that for every map is a pain in the rump.

Going to get some logging going for the converter lockup versus gear & throttle pedal%. I think I found the maps but the numbers look strange. Also, the Fords seem to use multiple columns per gear within a map. If that holds true for our cal file the start and end of columns will be hard to identify. I have seen maps in the Fords where sometimes the converter is locked full time in an upper gear. That means zeros in the whole column. That makes it easy to find and determine map column height. It does not look like we are going to get that lucky.

That was not my intention . It's a pitty I've got the GKE211 in my e92, perhaps I'm able to understand the way of remapping and do it for the 211. Which tools are neccessary?

Yes they do look promising! Don't worry about the x axis. It's close enough to imagine a 0-100% throttle input. Or are you sure it goes to 11?
I'll try to confirm the shift points with some logs but unfortunately I'm back to 12 hour days at work. Not much energy left for fun stuff.

Can you post some of the lock up clutch tables? Why would they be different in size?

Actually, yes I am relatively sure they go past 100%. First reason has to do with sensors, throttle position in this case, may go beyond the defined millivolt level of 100%. Second reason has to do with some Ford maps also showing over 100%. Strangely enough, this seems to be a more common practice with aftermarket tuners than OEMs.

I can do the same.

I can post the infield data. But without being sure of the column height, I'd just be guessing at the tables. I do not have any idea why they would be different, however, the inventory of probable maps says there are not enough maps with 13 y-axis cells to account for the shift maps and the TCC maps. The y-axis is the same in the Ford maps. So, we either need to find a method to discern additional 13 cell y-axis maps or look for them elsewhere. I am investigating both possibilities.

So far only a text editor, excel, NCSdummy and the Toolset32 (Ediabas, WinKFP,...). Since you already found out which family you have, I assume you're familiar with reading the AIF through Ediabas and have the daten files?

Yes, you can use any of the numbers I posted to go with your transmission. They should flash with no problem. There is one newer file for you transmission:
7606261. They seem to be ordered in consecutive numbers.
Look at the attached file: Your HW number is 7566894. All lines that include that HW number are flashable with WinKFP in comfort mode.

I'd like to do a little test: Make the downshift lines absolutely flat (same values per downshift). That way, the tranny should lock in one gear once it has shifted into it unless you slow down. You could then roll in the fuel without the tranny downshifting.
Very little risk and easy to verify if we tampered with the right map.

I'm in the midst of upgrading my map finding tool and have it inoperable right now. But you and the forum will have it shortly after I do . In the meanwhile, this is what I can tell you. After the first block of zeros, use the data value "534C" as the starting point, row1 and column1. The infield data for the shift maps is at row 7839, column 6, starting with value "0122". The maps do not follow Bosch format (that's why I could not find them at first), but rather run infield data consecutively, 10 columns, row 1 to 13, 10 maps, in that sequence.

I'd like to do a little test: Make the downshift lines absolutely flat (same values per downshift). That way, the tranny should lock in one gear once it has shifted into it unless you slow down. You could then roll in the fuel without the tranny downshifting. Very little risk and easy to verify if we tampered with the right map.

I'm assuming the purpose of your test is to verify maps. Because map switching is likely to be an integral part of the shifting strategies. The most efficent method is to modify the maps so that there are differences between them that is measurable through data logging. In such a senario, for a pairing of gear and throttle%, the OSS value would be unique to 1 map. So, I agree your technique would be effective and should be extended to ensure uniqueness between maps. The 4 maps I shared are the only ones out of the 10 that could be associated with D mode. The other 6 have flat OSS values with repect to throttle% in 1 or more gears. We have more than enough bandwidth in OSS to be able to make discernable changes 4 different maps. So that really simplifies things - unless there are other maps we haven't found yet. That could make me do this , ha.

Alternative experiment: Lower the full throttle shift point of second gear. Make it different for each map. Do the same for very low throttle (maybe raise the shift point). Do we get a different map, or the same map? One more hint is the "SA" parameter data I shared of few post ago. Note that those values denote upshift, downshifts and steady state by gear (and more). It makes filtering the datalogs to find shifts easier.

Because you are working 12 hour days and I am not, maybe I could give this tranny flashing a try. I may need a little coaching.

... I hope nobody reads that last paragraph out of context

Yes, I have the daten-files and know how to read the AIF. Btw I was wrong: I've got the 215, not the 211. For the 6-zylinder diesel there is only one mapping available in the data, so where to start? Thanks in advance!

Edit: There is also another question: A lot of people like to see the curent gear in D and DS (like alpina). Do you see a possibility to combine the "stock"-mapping with this feature like a kind of a mixture between alpina and stock?

[DWR]

I'd like to see that too. Sounds like a coding question. Any coding experts in the house?

Unhappily it's not a coding question . It must be in the Daten-file for the Alpina.

Yes, that'll probably a single value in the cal file different from the standard cal file. Probably impossible to find unless it is in a field of same values.
What do you mean, with "only one mapping available in the data"?
