ForScan is' limited' compared to UCDS.
UCDS = Russian made, as you know.
I am not working with UCDS, a friend does. And he has done the changes to my mondeo
If you want to use FORSCAN , it is 'scan' for errors and in some cases, you can change parameters .
Obviously, with UCDS , you can do all of this, but that program can dig deeper, if you know what I mean.
If you want to add features/options, In 9 out of 10, you must rewrite the modules. This can be done with UCDS.
That's what I know. There will be other advantages, too, I guess
As far as I know, you do not have to access the IDS database and I believe, it is also for the fusion..
