XO really doesn't have anything to do with auto targeting...auto targeting is where you point your scope at a target, lock it with space bar, and shoot without any sort of input, i.e., arcade mode. The TDC calculates the necessary shooting solution based on target speed, distance, angle on bow, and the bearing at which your scope is pointing. You can use the XO to input this information by calculating it yourself and telling him the figures, or you can use TDW's UI to manually input these figures using the dials. Turning the TDC off stores whatever information is already in it (speed, distance, angle on bow) without updating the torpedo's gyro angle to match whatever bearing you're looking at through the scope.
I'm guessing that you were instructed to turn off the TDC as part of a Fast 90 attack tutorial, right? Using that technique, disabling the TDC is a necessary step because your torpedoes are going to be fired at a 0 degree angle, straight out of your boat, but you'll be looking at a different bearing when you do your shooting; if the TDC was on, it would adjust the gyro angle of the torpedoes to match your scope wire, ruining the attack.
Edit- I may be mistaken with that last bit. It's been a while since I used a Fast 90, so I may be telling you wrong. But my description of the TDC is accurate.
