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 vibe zero magnitude="0.0" // Magnitude of steering vibration at 0mph (reference point).

FFB steer update thresh="0.015" // Amount of change required to update steer force/vibe (0.0 - 1.0). Lower values = steering force updated more frequently = lower frame rate.
FFB steer friction coefficient="0.1" // Coefficient to use for steering friction. Range: -1.0 to 1.0

FFB steer force balance mode="0" // Mode for how to add the steering forces together (lateral, load and diff). Acceptable values: 0 = lat + load + diff, 1 = sqrt(lat^2 + load^2 + diff^2), 2 = sqrt(lat^2 + load^2) + diff, 3 = sqrt(lat^2 + (load + diff)^2), 4 = sqrt((lat + load)^2 + diff^2)
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 rack factor="0.0" // How much of the lateral forces comes from steering rack. Range: 0 - 1.0
FFB steer load change exponent="1.0" // Exponent for the change in load on front tires. Range: 0 - infinity
FFB steer load change breakpoint="1.0" // Breakpoint (value that will not be changed) for the exponent on the change in load on front tires. Range: 0 - infinity
FFB steer spring coefficient="0.1" // Coefficient for steering spring. Range: 0.0 - 1.0
