I’ve tried all of the different DCT tcu software and IMO the GTS version is by far the best version. The DCT is a MT and, therefore, you have complete control over the gear selected and engine rpm you want. IMO to get the best experience and the most performance from the e9x M s65 you must use the DCT manual (S) mode in all driving conditions, even during the engine warn-up cycle where you don’t want the rpm to exceed 3000 rpm. BPM sets the cold limit to start at 4500 rpm and I wait at least an additional 15 min after the red lights go out on cold days before I come close to hitting the raised 8600 rpm redline. I prefer to drive DCT-equipped cars like they have a MT because they do have a MT. I have three DCT-equipped cars (four if you include the SMG with CSL tcu software and a lightweight flywheel) and I’ve never once driven any of them in auto (D) mode. The DCT IMO is not used in the g8x because too many people drove a DCT in auto (D) mode and complained to BMW that it’s a terrible automatic transmission so BMW gave them what they wanted a rear 8AT. The 8AT is one of the main reasons I won’t buy a g82 ending my streak of buying all of the M3/M4 generations.
