It will always say 'CAL' after running a firmware update - this is to recalibrate the wheel centre. The way you do this is described on page 31 of the V2.5 manual. The required button combination depends on which steering wheel you have connected - in your case it would be the two sticks.I updated the wheelbase.
When reconnected the display on my clubsport f1 wheel is flashing, and it says CAL, which I can read means lack of calibrating. what can I do from here?
