It's just the software logic and hence use of parameters/sensor input that seems to be the target of the homologation. Which gives them ability to control what type of sensors are allowed to be used, and what they control. This is the central part of article 5.1.e, and makes perfect logical sense. It's the only way they can enforce those rules.
In such case the rpm limit and boost should be fixed parameters. And the software logic should not permit those to be exceeded. However that doesn't mean though that you can't have other parameters/settings that can be tuned. It doesn't make sense as it would be too technically limiting, and nothing either indicates such to be the case. So to me it looks clear that every car can be set up differently.
