Did you change your control layout? I put accel. on R2 and brake/reverse on L2. I also put shift up on X and shift down on square.
I use the X an [] for Acc and Brake => standard.
I have this since GT2 and I can´t do the R2/L2 thing which Burnout/NFS has as standard.
Maybe I´m too accustomed to the X and []![]()
