optimize G31 LCI. May help you too. You can use this as reference for G/F series.

Please pin this post, it my help others with G maybe F series. I use Ista+ and BimmerUtility but E-Sys may be better for you. 
If you are a pro at E-Sys please make a tutorial and let it pin the post so that everyone can see there. Thank you.
Lets start with what I did and fix many issues that I found on internet.

The steps to add programing for Ista+ is fallowing:

1.Install Ista+ (in my case ISTA_Standalone_4.39.20) standalone without programming files
2.Unpack PSdZData (in my case v4.46.41_PSdZData.7z) to C:\EC-APPS\ISTA\PSdZ\data_swi....in case you don't finde data_swi create a folder.
3.Go back to the Ista+ installation folder and go to "files_only_for_manual_install"
4.Run the fallowing files in order: - ISTA_firewall_rules.bat (run as Administrator) - ISTA_Reg_Fix_min_x64.reg - AppCheckDisable_to_use_different_DBs.reg
5.In the same folder you have regfiles_full_sdp_blp there you will finde ISTA_Reg_Fix_x64.reg...edit it and change the version of the PSdZData ex. "SWIData"="4.46.41"

(optional to program with ENET cable(is not recommended) see this: https://mhhauto.com/Thread-Programming-w...D-and-ENET

SAS3
in the search bar write segeln and choose Nr001 and at topologie you choose what type you have dcc or acc or both if you have. (acc=assistant cruse control....dcc=dynamic cruse control)

I may update it with the time

[HarryMidnight]

Really great work! Wish I had this as a starting point when I was getting into coding my G12.

Just a couple of questions:
1. Have you had a look at the options in SAS3? Quite a few DAP features depend on it - interested if there's anything worth messing with. At first glance, there are some intriguing ones like "c_acc_verlaegertes_wiederfahren," "c_acc_reaktion_kreuzungen," or "c_ueberholhilfe_beidseiting."
2. What's the "gesetzesrelevanz" parameter for? By default, mine was empty.

Thanks for the detailed guide!

[Silent1990]

I'm not really a pro but still testing, this is second time when my HU brick now and I need to try to repair...for whatever reason it bricks but till now i never hear someone saying because of coding you can burn your HU.
Yes i know about those 3 and i have them activated but they are not really doing themself what in description says...
gesetzesrelevanz I'm assuming that is for how should solve the problem to prevent collisions and preventive measurements....gesetzes=rules relevanz.

I think....this maybe is different meaning.

[SimR]

Note that in my case I broke my HU by setting wrong parameters in "COMMUNICATION_PARKMASTER". So I think it is possible... Be caution!
