Also coded the F80 for the following as my version of ISTEP ( car software )is circa 2017 .It had the GTS coding option in current software on three of the modules. Simple coding and no flashing required.
BMW F82 GTS Steering
BMW F82 GTS diff
BMW F82 GTS MDM
Really like the steering change and has closed the gap between the superb old E46 M3 and F80 running lightest steering option.Its nicely weighted. The deadness has gone on straight ahead its is really nice on twisty roads
Sport mode is heaver still and reminds me of of my old e21 323i which I always enjoyed. Sports plus is heavy to fast steering movements but seems like it would be good at ultra high speed like if your on the autobahn.
Diff coding change has made the front and rear more in sync and turn in seems better.
Still running standard DTC software and Engine software , but like the rawness of the current engine software.
