You need at least a base level of autism to be able to really make a fanfic work. The difference is it needs to be the autism that comes from understanding the source material and yet wanting to do something with it that doesn't quite happen in it. If you try too hard to keep things the same, you end up like those youtube "what if" spammers that give abridged summaries of fanfic ideas that keep trying to get the plot back "on rails." If you try too hard to make things "better" than the source material you end up with shit like Multiverse and all its attempts to "outsmart" Dragon Ball. Not trying to do a little of either can also make for a boring story, though; it's all about the right balance.

When trying to take "good" ideas, you should see how they work with whatever premise you have for your fanfic first. If you have a fanfic idea like, for example, "AU where Goku and Caulifla are siblings" then working in some way to make "back tingles" sound less like Toei bullshit and more like something about martial arts and how Ki is channeled might be fine. But the same fanfic idea probably does not need an in-depth explanation on how Capsules shrink materials without violating known real-world physical laws.
