I edited my post above a min ago as well. Basically showing that PS4 by licensing the CSL wheel, in effect support load cells for Fanatec as this is a function within the wheel and where calibration is controlled. Here’s the thing though. You don’t always press the same the first time. It’s track dependent if the first few corners are lighter on the brakes. That would cause a issue if us Fanatec users needed to calibrate like others. The lack of any issues ever points to it not being an issue with Fanatec. Correct it’s not a on/off BUT it’s very simple to apply full pedal travel as there is very little resistance relative to a load cell. With AC it was for PS4. I have AC/PCars/GT and never have to calibrate any of them.
