Socionics types list 2 valued functions, followed by 2 un-valued ones that oppose the first two, followed by 2 valued function, and another 2 un-valued ones that oppose the second set. This is different from MBTI which lists 4 valued functions and doesn't talk much about the the other four.

Socionics list of functions for any type is like this:

Ego block - 2

valued functions

Super-ego block - 2

un-valued subdued functions

Super-id block - 2

valued needed functions

Id block - 2

un-valued mostly ignored function

MBTI functional listing is as follows:

4 valued functions

So of course for any type the order of listing of the functions is going to be different for MBTI and Socionics.

But which functions are valued does not change. This is important to notice.

Socionics ENFp type values Ne, Fi, Te, and Si, which is same as the valued functions listed for MBTI's ENFP.

It's just that the order in which they are listed is different. This comes from Socionics Model A where Superego block functions are considered to be conscious and in close relation to the Ego block functions.
