Narrative:

Before our taxi; we had been given runway 31R. Before beginning our taxi; we asked for runway 36 and was granted that runway by ground control. During taxi; we changed the departure to runway 36 in the FMS. Upon switching to tower; they stated we would need to turn to 310 degrees before the airport boundary. We could not comply; so we took runway 31R instead. Unfortunately we did not change the runway in the FMS. During the climb; we hit the nav mode at about 900 ft; and the aircraft made the turn toward 360 as it would on the runway 36 departure. We were in the middle of correcting when tower advised us to turn back to 310 and contact departure. The break from our briefed departure and last minute runway change lead to the deviation. We should have made another complete brief following that change to review the departure with the aircraft stationary.
