Hello, do you play with the original GP4 (2001) or with the CMS / TSM ??? I use the keys V = speed, B = brake, <turn left,> turn right and F / G these are due to the configuration, my gear is automatic. In the mods, some do not allow the use of the V key, so I use A and S. Start the game go to Options / Controls / Keyboard and check if the Changedrivekeys option changes its tone, if so; define the keys to your liking, if not; go to Advanced / LoadControlSet / OK / KeyboardSetup and see if the Changedrivekeys option changes its tone if so; proceed as above. Sou brasileiro. (google translate)
