GTS coding LSD(GHAS), DSC (MDM), EPS (Steering)

[alexdaoe]

Hello, I have a 2017 LCI M4 and I just did the GTS coding by changing C_Variante_Fahrzeug_e (on DSC ECU), DSS IPM & TASC (on GHAS ECU) and variantencodierung normal (on EPS ECU) to F082GTS with E-sys.

It all went great and now I have GTS coding for LSD, Steering and MDM. Now I want to try this coding on an early F80 M3 2014 (before the GTS was launched) and I'm wondering if this will be possible to do like on mine without fully updating/flashing the ECUS to the latest version (on mine I just had to change the values above mentioned from f082 to f082GTS).

Thanks!

No one knows for sure? What should I look for? If I see the option to change f082 to f082GTS it's for sure not necessary to update ECU's?

Nope, you will have to do an istep update (achieved with the full PSDZData) to be able to flash a pre 2017 car. I'll link a guide to get the istep update going in case you need it, I used it just today to run a istep update and the gts flash

Hi! I ended up trying it and it was no problem no ISTEP needed just the f080 to f082GTS method and it was in an early early 2014 f80.

The method mentioned is described in this post:

Guess I'm *that* person bringing an old thread back to life... but hey, here I am, resurrecting it like a social media zombie! ��*♂️

I read a lot of different information regarding GTS coding.
- Can the GTS coding be done by E-Sys via FDL Coding only (as stated above)? Or do I still have to Edit FA?
Thanks in advance.

FDL coding is enough
