Bimmer Scene - Latest BMW Coding / Retrofits / Maps

Hello everybody, here is my first question, since I am a total beginner as far as coding a car is concerned.

I recently bought a 2017 F31, that is equipped among other things with the option sa 843, causing the car to have 14 HP less than it should.

My question is how do I exactly go about coding it back to standard DDE map instead of the one currently installed in the car.

I have already tried out a few things with ista D but this is a completely different task.

I guess the VO needs to be changed before a DDE update is carried out but how exactly does one do that?

Kind regards.

Won't someone give me hints as to how to do this. I need to update the DDE module but I need to update it with the correct data. I am sure many of you could do it in the blink of an eye. Thx

Esys is the way to modify vo and calculate the flash and coding for dme

Hi Bosch.

To remove $843 you must (hope you know basic of E-Sys)

- Remove $843 from VO and write new VO to car.
- Code DME with new VO (without 843)
- Calculate TAL for update DME;
- When you go to TAL Processing, mark only DME (be sure that option are marked: swDeploy and cdDeploy).
- Update DME.
-Job done.

For safety reason, when you flashing any module, use external power supply (gys, mst). And you need full pszdata, not lite version

There is a procedure on f30.bimmerpost.com if you search for it on there.

Thanks for the excellent answers . I will try to find as much info as I can as I don't want to brick the ECU. I'll tell you how it went. I hope to get it done this week end.

Thanks to all these good advices I managed to successfully flash the DDE to original spec. I only have two modules to go to bring everything to the same I step, but I have to find more info about flashing these:
Acsm.
Nbt2
They where on the prerequisites so I should do them but I am unsure as how to lock acsm once flashed, and the nbt works great, I might not fully understand that prerequisite stuff though.

Anything for g01?
