THOR_Flasher, I'm very glad that you bring this TCU flash to F8X.

There is a consensus in the M3/M4 community that OEM GTS works brilliantly with S55 engine. It clamps better, shifts faster and removes all the jerkiness at lower gears.

The same cannot be said to F87 M2 N55, with which throttle and shifting cannot be separately configured. The DCT seems not to be fully compatible with OEM GTS transmission software. The "symptom" after you flash through, is that however you toggle between C/S/S+, the shifting gets always stuck in GTS comfort, throttle response adjusts accordingly though. Also, you have C1/C2...C7 gear display on dash, instead of D1..D7 prior to flash.

I was the early trier of GTS gearbox in early 2017 and flashed back to stock in a few weeks.

If your software just codes GTS/CS file to F87 M2 N55, the symptom said above could happen.

Please double confirm that your software is not only flashable with F87 M2 N55, but also "properly working" with it.

I'm 100% in, if THOR software works as intended.
