Haptic Clutch in gt7?

Hello all,

I try to add some haptic effect on my clutch in gt7 but i don’t find something good.

Haptic work when i active gear shifting but i would like that the clutch vibrate when i push the pedal.

i try a formula in custom effect but it’s not working… 

I set mono, select front right and add this: if([clutch])>75,100,0)

am I missing something?

thanks for your help!
