I know the US TDC's did, and assume the KM's did as well, but as Hitman suggested, they were imperfect machines. O'Kane mentions in one of his books that they checked and calibrated the TDC between patrols and it would calculate the correct angle to 1/4 degree. He considered that sufficient, because the torpedoes were said to be able to hold course to within 1/2 degree.
