you can do it with the mini tweaker but the game won't allow less than 1 second on opening the doors so the firing by default must be more than 1 second or you blow yourself up.
you can speed it up a little by setting firing to 1.1 instead of the stock 1.5
this would feel like instant firing when hitting the button. preopening the doors speeds things up a lot as well.
opening closed door = 1 second / firing = 1.1 second > launching torpedo = 2.1 seconds
preopened door = 0 / firing = 1 second > launching torpedo = 1.1 seconds
