No, timing cover does not have to come off. Just make sure #1 cylinder is at tdc using the feeler in the #1 spark plug hole method.
Then as shoebox said, install crank hub so arm with raised mark will be at 12 o'clock position. Then put damper on. It will only go on one way.
Because of the way opti drive is designed, when installed correctly, it will fire cylinders in correct order.
In case you don't know which cylinder is #1, its the front cylinder on driver side of car.
Here's a diagram of spark plug wire attachment to opti.
