Does anyone know if the autosplitter works in coop?

To setup the timer with 0x skulls do the following: select everything through the menu normally, including the timer, but stop when you get to the skull select part. Once here, select the skulls you wish to use, but then, press up on the d pad to go back to the bar on the top of the screen: DO NOT PRESS RIGHT BUMPER. Press right on the d pad now to go to start game and press A. Now you should be able to start your game with the timer.
