[RESOLVED] CSW 2.5 calibration not working with PC2 / AMS2

I hope this is just a novice mistake (CSW 2.5 under a week), but I have issues calibrating CSW 2.5 + F1 wheel in PC2/AMS2.

• Initially setup worked, angle/calibration is correct.
• One day wheel doesn't react (but buttons are fine). Calibration is at 0.
• Followed online advice to remove the controller setting file
• Now calibration works, but incorrectly calibrates - wheel moves ~25% slower than it should be
• Followed the Fanatec AMS/PC2 setup guide
• Reinstalled the drivers (official driver and latest beta driver)
• In the USB Input Controller setting everything looks good
• Switched SEN from auto to 900, and the same issue. It calibrates with Steering Range 97 and Steer Lock 296. Wondering if the lock is too low? I have seen 900 online.

Any thoughts? Given that the Fanatec software is showing everything correctly, and it is identical between PC2 and AMS 2.0, I assume I must be overlooking something obvious.
