One at a time. It will go through the entire binary and match it to the 730 offsets. Some parameters disappear, change in size, or shift locations.

It would probably be worth blocking out areas where its already found a match.

This is really only useful for research purposes, since the 730 software version isn't up to date and nobody likely has it left on their car. Updated XDFs for newer versions (including MSV80) are next on the list.

A translation mechanism is built in, I just need to build the database of translations. There are too many to do by hand, so I'll probably use Google for it and just fix the ones that are obviously mistranslated. For now, you must read auf Deutch!

BTW, there is a bug in TunerPro that doesn't allow it to use more than 255 categories. MSS70 has almost 900 categories, which breaks TunerPro. Just sort it by "Parameter Type" or "Ordered List". I have something in mind to deal with this but I need to finish building my tools first.

Great work. Does this mean we can tweak the throttle delay? (assuming: we read german, have the same versions, correct tooling etc.)

[hassmaschine]

to be honest I never really noticed any throttle delay on my 330i, but likely yes, you could tweak the throttle settings - if you can figure out what parameters need to be adjusted.

you probably don't have software version 730 though. most 330s will be 9XX. But that is coming next..

I sucessfully generated an MSD80 xdf but i don't have a matching bin... Doh! I have a different version that i can use though.

Why care? Well, msd80 is basically msv80 without valvetronic. In fact, the development name for msd80 is msd70. They're all the same DME family (mss70, msv70, msv80, msd80). I think i can use MSD80 to generate an xdf for all msv80 versions. So the rest of you guys can do what the 330i can already do...

[rjahl]

You are certainly on a roll.

I'm still stuck with the logging. I played with something today that multiplied my data rate with Testo by a factor of three. Looks really promising.

That is really great work! Finally it is getting interesting for me again :P

Really looking forward to this to be finally able to replace my OFT tune with something really sensible

I successfully built a crude search mechanism. I need to improve it quite a bit, and weed out false positives, but it found about 90% of the maps without issue. I haven't included single values at all yet, but I was able to generate an XDF with (mostly) correct offsets from the 730 software to the 921 software.

With some additional tweaks I should be able to search in MSV80 as well.

This is really great work. Where do you see this project going? Your not starting to think VW diesels are you. LOL

[hassmaschine]

Heh no, but i want to expand it to as many modules as i can!

[hassmaschine]

no, I haven't worked on it in a couple weeks. my wife hit a deer, so the 330i has been sitting waiting for a new left eye. She managed to miss 2 out of the 3 deer that ran across the freeway while she was traveling 70mph; it's amazing what little damage it did.

[David0ff]

WOW glad she is OK!

[hassmaschine]

It wasn't so bad - she was more scared than anything. literally, it only broke the headlight and there's a small crease in the hood. when she called me to say she hit a deer I was imagining much worse!

Only just seen this thread. Very eloquent method of tuning by the OP.

Just checking you guys are aware of BMW Intelhex to bin. It's an app to convert BMW 0da / 0pa files into a hex format which can be opened in winols for example.

The beauty of this is that changes can be made in winols and then converted back into 0da / 0pa so that your custom maps can be written via winkfp.

Check it out here: https://github.com/macadam76/BMW-IntelHexToBin

Unfortunately development has stopped. But it works well I find.

I've been there done that, can't get past the DME rejecting the rebuilt ODA file. Even with all of the checksums corrected. We need to get past the RSA signature protection to use ODB. Much easier and faster to use the BDM plus you never crash or "brick" a DME.

RSA can be bypassed. I've seen this exact method for flashing Tri Core protected EDC17 ECU via ODB. However that's a different story.

I agree, BDM is a fine method. I like the OP's built in header. It makes my home made jig and pogo pins seem needlessly over the top.

I used the header method as well. I have a friend that is very good with soldering circuit boards and it was easy for him.

RSA bypass, interesting. Before I hit that wall, I was hoping to share how I upgraded my software to a Z4 3.0SI. Building the Files or patch is fairly easy.

The is a fascinating post and I intend to read all of it when I have time. In the mean time, I have a quick question and I apologize in advance if this has been asked and answered before. Assuming for a minute that I have no diagnostic access and no physical access at all to my car, is there anyway to know which ECU Type/DME Version is installed, MSV70, MSV80, etc.? My car is a 2011 E90 N55 335i.

[hassmaschine]

you don't have any of the above. I think the N55 uses Bosch EDC17 or something - I'm not terribly familiar with the N55, but I know it's not MSD80. you can check by looking at the bottom of the DME.

Google BMW VIN decoder, more than likely you have a MEVD17.2 DME. To verify, list all installed control modules using INPA...E90 -> Select E90 -> Functional Jobs -> <F2> Identification.

[Nicholas Bentley]

I've decoded my VIN several times at different sites but I've never seen the DME number listed. I don't have a cable yet, but I'll be ordering one soon.

All N55 from 2011 - 2016 have the Bosch MEVD17.x DME, and S55 use it as well. Some of the early N55 in 2011 can be tuned via the OBDII port and the only company that has a hand handle plus a tuning app for the end-user is Cobb. From 2012 & up needs to be benched flashed or a spiderboot $$$ can be installed to open access to the OBDII port.

[Nicholas Bentley]

Thanks for the info Bob. Mine is a 10-28-2010 production date 2011 model.
