Hi.
in any mod/super mod before you enter data into TDC, at TDC station (default F6) you have to "unlock" TDC by pressing a switch (1/0) or by using combination ctrl+t.
After you enter data you lock the TDC back on. So when you move your scope, gyro angle moves accordingly. Did you do that?

Also when you enter data on scope view (F3) it is good to press a tick mark (v) on a notepad at lest two times. First click "approves" data you collected, and the second click updates the TDC.

When you have above steps done, you should aim the scope into a spot on the ship that you want to hit and TDC neddles should move accordingly.

When you set salvo spread, remember that torpedoes disperse radially from the spot you aimed.

So if you set 2 degrees, and fired two torps, they will hit 1 deg to the left and 1 deg to the right from chosen spot.

Also remember that at 1800 meters, 2 degrees mean arround 60 meters of dispersion and your target has only 150 meters. If you didnt' aim at the center, one of torpedoes may miss.

Remember about torpedo depth too.

And BTW install some mod which gives you TDC on attack scope and preferably some mod which offers U-jagd watch to measure speed by chronometer only.
