It could be. I haven’t ran in US spec MDM for awhile. If I shift too hard and chirp 2nd or even 3rd the nanny will kick in. But I usually get a flash.
If people don’t mind the potential warranty void.. ( yes I know. Some dealers now flag you for coding sigh... ) coding in M4GTS EuroMDM is quite possibly the best thing you can do. Really let’s you explore the dynamics of the car with just enough safety room to bring it back if you miss a correction.
