The timing and the rotor are independent, you can adjust it the same no matter what rotor you have. You'll notice a notched black plastic ring at the "endbell" end of your motor. Loosen the the 3 screws that hold the cover on the back of the motor and you can turn this ring. This adjusts the timing. Turn it counterclockwise to increase just like a brushed motor. What it does is moves the circuit board that contains the Hall chips that commutate the motor. Moving their postion relative to the rotor adjusts the timing.

Different motors like different timing so there is no set place to put it that is always right. You can't really turn it all that much so don't force it or you'll probably end up like the person who started the thread.
