Hello everybody!
Is it possible to deactivate the virtual speed in the TTS4 software?
I can calibrate the role as I want, the difference is always 5-6 km/h.
Or can you enter the calibration manually in a file?

Virtual speed and calibration are completely different aspects of the software. Most software these days uses virtual speed calculations to display the speed of the rider as accurately as possible for what it would be in the real world, based on the rider's net power output together with the inputted weight of the rider and the bike along with forces on the course like slope and road surfaces (there are others as well).
So, if the difference you are referring to is between a separate speedometer you have on the rear wheel and what the software reports, they will by necessityl always be that way and it should be. If you try to make them the same, you will end up with an inaccurate reported speed in the software.
Calibration is the process by which the software calculates the amount of friction in the particular system being used. Typically, calibration uses some kind of roll-down test. The bike and rider are brought up to a predetermined speed and then allowed to coast to a stop. The amount of friction in the system correlates with the how much time it takes to come to a stop. Various factors affect this, most importantly tire pressure and roller tension, along with mechanical friction, like the chain.
It should be noted that these trainers, particularly the older types like the Fortius, Vortex, Flow, etc., are not in any way laboratory grade instruments. 5-10% accuracy is probably realistic.
