I think this is not for Thrustmaster T150 settings, It’s for T150 Pro Model (w/ T3PA)
Because Default Thrustmaster T150 Key settings is wrong.
You can see, Gas Pedal is Axis 4, and Clutch Axis 3 (If you play FH3 or FM7, T150 doesn’t have Clutch says “None”)
When you active custom settings and check, We’re Gas Pedal is Axis 3.
So we have to wait until it is solved.
