A lot of you probably already figured this out, but for those who haven't:
InputGearShift1 = "JOY2_BUTTON3,JOY1_BUTTON1"
InputGearShift2 = "JOY2_BUTTON4,JOY1_BUTTON2"
InputGearShift3 = "JOY2_BUTTON5"
InputGearShift4 = "JOY2_BUTTON6"
InputGearShiftN = "!JOY2_BUTTON3+!JOY2_BUTTON4+!JOY2_BUTTON5+!JOY2_BUTTON6+!JOY1_BUTTON1+!JOY1_BUTTON2"
InputGearShiftUp = "JOY1_BUTTON1"
InputGearShiftDown = "JOY1_BUTTON2"
JOY2 is my act labs shifter.
JOY1_BUTTON1 & JOY1_BUTTON2 are the shift paddles on my Logitech MOMO that I wanted to use with this game.
When no gear shift buttons are pressed, it will register neutral.
It should work the same with a G25 or G27, provided the correct JOY and BUTTON numbers are substituted.
It's the same neutral fix mentioned here, but I wanted to use my paddle shifters:

EDIT: Also want to mention that InputGearShiftUP works to upshift, but InputGearShiftDown doesn't work to downshift in LeMans24.
However, InputGearShift1 & 2 work fine for upshift and downshift. That's why the paddle shifters are added on to 1st & 2nd gear.
If InputGearShiftDown worked to downshift, they wouldn't have to be.
