Clubsport V3 brake calibration setting is fluctuating wildly at rest
As it says in the subject line, my Clubsport V3 brake pedal has started acting very strangely. When I go to the Fanatec Wheel Properties page (where I calibrate the pedals' travel), the vertical calibration bar indicator for the brake pedal is fluctuating between about 20% and 50% of its range. I've noticed that during recent sessions (in rFactor2 in a Radical SR3), the car often appears to be significantly down on power, and my investigation quickly led me to this. It makes sense that the game thinks the brake pedal is depressed up to 50% when I'm not even touching it could create a significant amount of drag on the car's ability to accelerate.
What can I do to troubleshoot, and hopefully quickly resolve, this problem? I'm in a bit of a state of panic, because I have a 3-day real life race school at Atlanta Motorsports Park starting on Thursday 3/18, and was planning on spending a good chunk of the next several days practicing driving AMP on the sim to prepare, so resolving this quickly would be GREATLY appreciated. Thanks.
