UPDATE!!! German tuner LEIB Engineering cracked the F-series DME last week!!!

I have been in touch with German tuner LEIB Engineering ( http://www.leib-engineering.de/ ) after their Facebook update last week about finally being able to tune the BMW F-series cars.

They have confirmed via email to me that they last week cracked the DME (or rather "found a way") and are now able to tune any F-series BMW!!!

The first car they managed to tune was a M235i that was tuned to 400hp just by software modifications.

These are some of the things they can do (on ALL F-series):
  • Delete the engine lights (if the car has been decatted)
  • Open the v-max to unlimited
  • Apply a new (bigger) set of turbos to the software
  • "Program the F-series with every wish, that we or a custumer could have"

The tuner is based in Germany, so it might not be available for all the US members on this forum.

EDIT:

This is the latest developments regarding DME software modifications from LEIB Engineering:


They are now able to ship already tuned DME’s to customers. At present time this currently only available for all N55 and S55 engines.

M5/M6 will be the next. It will be finished in the end of September.

Completely opened Vmax, deleted CEL and more is possible.


The first tunes are:
  • M135i & M235i: 390 PS and 525 Nm

  • M3 & M4: 550 PS and 650 Nm

  • All other x35i(s): 360 PS and 500 Nm


The customer can keep his own DME. They can now ship the already tuned DME directly to the customer.

All they need is some basic info of the car, in order to flash the correct base software.


They have also lowered the price AFAIK

I'm not sure that E85 tuning is that big in Germany...

Also, they claim to have opened up this generation DME only last week, so I think we will have to wait a bit for more evidence here...

So far, all I have is their word for it via email (but that might change )

Agree that a bit of healthy sceptisism is in order after all the failed attempts and promises before...

This time there are more rumours/reports than before though. And over on the M5 Board there is one member that is in contact with them about a tune now. Hopefully we will know more soon

Hopefully they aren't just reselling the M5 competition package file, like some companies have been known to do.

Latest info from LEIB Engineering after talking with them:
  • They do NOT use press tunes or any other software from BMW for tuning. This was a point that they stressed as very important to know (they had read the forums... )
  • The current process involves them having to have access to the DME for 1-2 weeks and is very strongly secured and needs a lot of equipment and processing power and time.
  • One of their main goals at this point in time is also to keep the dme protected against other tuning companies, which for sure will try to copy their software. This means that their tunes also are encrypted and nott accessible for other tuners.
  • The other tuners, who also can do the F-series, will be delivered directly by LEIB Engineering.

I will quite possibly meet them later in August and might be able to report more then

Sounds like a bench tune or a drill tune. I mentioned E85 earlier simply because it's very difficult to hide fuel trims / logs / tables w that fuel.

Bench means bench flashed.

Drill tuned means the way the AMg cars are done where there is literally a hole drilled thru the ECU box.

Then what makes this an adverse way to tune a car verse say ODB2, granted you aren't drilling into a part, and or taking your ecu out for days/weeks rendering your vehicle a paperweight.

The DME still has the stock BMW software programmed after they have done their thing. The tune is only installed when the DME is in the car.

They currently have three methods to this:

Quote:
1. The cclient comes to us with the car, we need the time of max. 2 and a half weeks to get the DME( ‘s) programmed.

2. The client ship the DME ( ‘s) to us, and after 1 to max. 2 weeks the DME ( ‘s) returns to the client (not tuned). After that the client has to drive with his car to us, to get the tune done. (This will take approximately 1 – 2 day’s)

3. We buy a new DME, and after 1 to max. 2 weeks the client has to drive with his car to us, to get the tune done. (This will take approximately 1 – 2 day’s)

Lol, all sound terrible. This is why the Cobb AP was revolutionary.

With those 3 options in play, if we arent in europe, then we're screwed! Does this sound accurate?

Probably, at the moment...

Hopefully they will cooperate with a US tuner (or maybe some US tuner also figures out something)

Great idea to pitch to them! That would boost their "product" sales by a very substantial amount!

Wow this comes from a well regarded tuner... Have loved what they've done on prior m3 projects and have extracted a lot of power from their tuned s65s
