I am using a wired xbox 360 controller and i just switched to xbcd 360 0.25 and it seems fine and well, but i am not able to use the clutch when i get into any version of lfs... It displays fine in the control setting menu. this is my setup:
left shoulder button- shift down
right shoulder button- shift up
right trigger- throttle
left trigger- brake
X- ebrake
Y- horn
b- flash
b- look back
d-pad up- zoom in
d-pad down- zoom out
d-pad left- look left
d-pad right- look right
start- ignition
select- reset car
Left analog stick- steering
right analog stick- clutch

i use semi auto but restrained to auto when i use XBCD can anyone help me?

Your main problem with this is that you are using an analogue stick for your clutch, which auto centres. Meaning the clutch is always half way through it's travel.

If there is a way to get the centre point of the stick to represent the extreme positive of the axis so that half of the travel of the vertical axis on that stick (centred - down) relates to the full travel of the clutch then it might be possible.

Maybe try calibrating the stick you want to use as clutch half way (centre - down) and do not press it upwards at all. But I'm not sure this would work.

Alternatively why not use a button for clutch?

no, i am actually fine with pulling the clutch all the way down to deactivate, it's just that after i installed xbcd i can NOT control my clutch
