By way of background, my 2015 F4 has been mapped with ECUStudio (can't recommend it enough - so much smoother) and downshifts with blipper enabled.
But I have an intermittent issue with gear changes which I am guessing is an issue with the QS.
When I go for a ride, up and down shifts always start off well and (clutchless) gear changes are initiated with minimal pressure applied to the lever. But after a time (no set time or number of changes) the pedal seems stiff and sometimes will not change without the clutch. If I pull the clutch lever, gear changes are always smooth and easy suggesting that my problem is not with gear box?
And sometimes it will work fine again after a few clutched changes ... or maybe not?
