I have assigned the buttons to buttons on my wheel, and when in game I press those buttong ERS does not change, I tried re-assigning to different buttons but still the same, only way I can change ERS is in the pits before going out in Setup.
More info might be needed to fully help you.
Are you referring to the SF70H?
Are you using the vanilla launcher or Content Manager?
What wheel/input device are you using?
The car from Red Pack DLC, I believe it's the Ferrari SF-15T.
I am using content manager, and have set the drs options to buttons on the wheel correctly.
I am using a Logitech G29.
Pretty much exactly same as my settings, and still does not move ERS, I can change it in settings in the pit with the mouse, but once I set it there, that's what I'm stuck on out on track no matter what I press.
Sorry, I'm not sure what else to try.
Have you tried any other hybrids?
There's the TS040, the 919, and the SF70H by Kunos.
Also the RSS Hybrids if you have any of those.
Might just be a issue with that car for some reason?
Strange.
Could you post a screenshot of your controller settings?
Include both Buttons as well as System if you can.
I'll give your settings a shot and see if I can reproduce it.
