Greetings and Salam.
I just got a MG HS 2021 94K odo CBU unit, in Pearl White, I swapped my daily driver with my brother, a few days ago and wanted to share some information that might be helpful to everyone here.
If anyone wants to turn AEB off on CBU units, just go to Engineering mode, page_7 and switch AEB to No.
And if anyone wants to reduce the jerks of the DCT transmission, you can change the way ECU/TCU handles shifting by changing AT to AMT on page_2 and then hit back button, and hit exit, it will reboot, saving these changes.
AMT (automated manual transmission) mode is less sporty but it's way better for city driving and I have observed a significant increase in fuel economy, I just finished one full tank with 13kpl average with 94K mileage on the odo.
