I know that you can go up it without stopping accelerating, but no matter how much I try, I either turn right into the right side chicane or I go straight out of the track on the left side when the hill ends. For reference, I'm arcing on a R8 LMS Ultra.
Yes, I did. That's how I found out that you can do it in the first place. Before, I just gave a quick break and shift down right before the uphill starts.
