I've managed to get it working in Dirt4, however how can you change the active car profile ingame? (i can change the profile, but it seems it doesnt get active when im ingame, only when i restart the game with the right profile, it works)
for example, i got a default rpm value of 10, 4000, 5000, 6000, ... but other cars (2000cc) require a profile suited for me like 10,4000,7000,8000, ...
You can only have one game profile active at one time. But you can add multiple car profiles in a game profile. Unless the game only sends 'default' as car name.
