Fairly common these boards they have X, Y and Z Axis showing in Windows in Game Controller yet they already have the hardware and labeled for W Axis (Clutch) and there is a model they sold with that function but i've not found any, 2 op amps that do 2 Axis each as I recently had the older type version of this and fitted missing op amp as it was only combined pedal setup, with 2nd chip it then worked with separate pedals (already showing)
Assuming the removable chip on right holds the firmware it can only need that updating to turn it into 4 axis showing but is it possible that someone could do this without having an original 3 pedal model
