We prove the effectiveness of the log litaka fibration in Kodaira codimension two for varieties of dimension ≤ 4. In particular, we finish the proof of effective log litaka fibration in dimension two. Also, we show that for the log litaka fibration, if the fiber is of dimension two, the denominator of the moduli part is bounded.
