I used a fresh install of the mod with the modified Gears.asi for testing. I set up the buttons through the in game menu but they didn't register any inputs or show any telemetry. It added these to the bottom of settings_wheel.cfg

[THROTTLE_BUTTON]
DEVICE = 0
BUTTON = 4

[BRAKE_BUTTON]
DEVICE = 0
BUTTON = 5

[THROTTLE] and [BRAKES] are set up to the default values in the settings_wheel.cfg in the .rar
I noticed clutch works the way id want brakes and throttle to since it activates the blue bar on the mod hud. If I clear the [CLUTCH] values though, it no longer works. So I was wondering if it still needs the correct MIN/MAX/AXLE slider to work.  Hope any of this helps. Thanks again
