Yes, I can monitor it in either ForScan or Torque for Android.
In Torque, you'll have to add it as a custom PID.
When you add it, set the min and max values to -1 and 1. You'll use header 2203e8. Name it whatever you like.
Here's the equation:
(Signed (A)*256+B)/-16384
With this configuration, values closer to +1 represent favorable fuel quality. This is how it appears in ForScan.
I've seen others use the equation with +16384 (-1 reading being favorable), but I wanted the measure to match between apps. Feel free to use whatever you want.

I'm not sure if there are differences between the iOS and Android versions of ForScan, and I'm not sure if the EU car's spec is different from the US, but I'm pretty sure that 100% indicates that you're running high octane fuel. I don't think you're doing anything wrong. I wouldn't expect it to deviate much if you fill up with the same fuel every time. If you fill up with a different grade each time you refuel, or if the fuel in your area is inconsistent in quality, it will deviate, but it should adjust fairly quickly.
What type of gas do you use when you fill up? I see you're in Italy, so I would think that if you're filling up with 98 or 96 RON, it would result in a high reading. I fill up with something roughly equivalent to 98 RON, and my car almost always reads 100% in ForScan. If I fill up with a lesser grade, for example an equivlent to 92 or 95 RON, I see the reading start to deviate within about 10 minutes of normal driving, assuming I fill up most of the tank.
