I don't use the Logitech pedals but a 3 pedal Advantage1 set that connect to the PC separately - so the Logitech pedals aren't connected to the wheel.
Maybe for LFS I need to connect the pedals to set the paddles for shifting. I'll try that out. With rFactor for example that hasn't been necessary. I wonder if once it's set I can disconnect the pedals. Soon see!
Thanks!
