Hello everyone!

I'm new to coding here, but I have been reading quite a lot lately about this topic. 

The problem is this, I just started coding yesterday and wanted to add SPORT+ to my F10 520d.

The thing is, I read that I just have to slightly modify my FA - to remove 205 and add 2TB. I did just that, but the problem is I applied it to all the ECU's, not only the ones that I had to (EGS, ICM, & KOMBI). Unfortunately, I didn't save a copy of the original FA (with the 205, without the 2TB), so I was wondering, are there gonna be any issues since I applied 2TB to every ECU?

And while we're at it, if I modify the FA again by removing 2TB and adding 205, will my FA be the same as the original or will there be issues of some kind?
2TB only applies to EGS, ICM, KOMBI so other modules the coding would remain the same. If you edit back 205 and remove 2TB you would have original FA.
