Karl.. its okay you've done nothing wrong its just jyri setup for his pedals etc. Easiest way is to paste the FFB portion of the text file into YOuR profile.
So paste this block into your current t300 control set:-
FFB Device Name="none"
FFB Device Name Alternative="none"
FFB Rumble Pad="0" // Type of FFB controller: 0=wheel, joystick etc with force feedback, 1 = pad with rumble motor
FFB Gain="0.85" // Strength of Force Feedback effects. Range 0.0 to 1.0.
FFB Throttle FX on steer axis="1" // 0 = Throttle effects on throttle axis, 1 = throttle effects on steering axis.
FFB Brake FX on steer axis="1" // 0 = Brake effects on brake axis, 1 = brake effects on steering axis.
FFB steer vibe freq mult="1.0" // Controls frequency of steering vibration. Recommended: 0.5 to 1.0, 0.0 disables steering vibration.

FFB steer load multiplier="0.7" // Multiplier for vertical load on front tires. Range: 0 - infinity
FFB steer lateral multiplier="0.35" // Multiplier for lateral forces. Range: 0 - infinity

FFB steer load change exponent="1.0" // Exponent for the change in load on front tires. Range: 0 - infinity
