Narrative:
Departing lax runway 25R via the holtz 9 departure at approximately 620 feet the flight director gave guidance to make a left turn. I proceeded to follow the command bars and the captain noticed that the turn did not match the map display. I then disregarded the command bars and followed the map display direct to dockr. ATC shortly after gave us clearance direct to pevee. I loaded the runway and departure at the gate and the captain and I both verified that the runway and departure were correct. I'm not sure why the command bars were not in sync with the map display.
