I've read a book of Freud, regarding the personality parts. Although the book was really hard to read, I noticed some clear distinctions with socionics definitions. I've made a simplified comparison (feel free to correct it), with the differences marked in bold.
...Freud's Ego: Counscious. The self. Negotiater between the outerworld, id and superego.
Socionics Ego: Counscious. The self. Negotiater between the outerworld and self.
...Freud's Id: Subcounscious. Natural drifts and needs of the body.
Socionics Id: Subcounscious. Developed but useless part of psyche.
...Freud's Superego: Subcounscious. Repressor of the id. Houses moral values and ideal self.
Socionics Superego: Counscious. Rejected alternative of the ego.
...Freud's SuperId: -doesn't exist-.
Socionics SuperId: Subcounscious. Needs of the psyche.
My question: why the differences, has Socionics used Freud's personality parts in a wrong way?
