Bucking while accelerating - DCT?

[M3SQRD]

Install the GTS DCT flash and the bucking is minimized/eliminated. I drive in S3 only and have zero driveability issues.

Do you know if it applies to the CS model? I know the GTS and CS share some features and I have wondered about the transmission setting/mapping.

I’m unsure. I believe kubex86 has stated the EPS is the same between GTS and CS, not sure about DCT. I’ve been driving an e92 M3 DCT with e92 M3 GTS DCT software in S5 (S6 with DSC off) since 2009 so perhaps I’m just used to driving M DCTs on aggressive throttle and DCT settings? I’ve had no bucking issues with the ‘16 M4 and GTS DCT software. I definitely did have some bucking issues with non-GTS DCT software but added GTS software ~1 month after purchasing the car. I always drive with most aggressive throttle and DCT settings.
