Narrative:
Departed reno airport in VFR conditions with standard instrument departure mustang 8; as filed.wind changed 3 times within a 45-minute time frame; hence changed the runway take off direction three times during that time. Captain and first officer double-checked textual description of SID: outbound on the 164 degree heading to (3) DME to rijtu fix; then a 'left' continued climbing turn direct to fmg VOR.after normal take off and climb to the the rijtu fix; the programmed FMS software and flight director V bars logic; sought out shortest turn to fmg VOR and falsely turned the flight director V bars to the right.initially we followed this flight path and very quickly; both myself and the captain realized this turn was in the wrong direction towards rising terrain; we quickly corrected the flight path and initiated a turn with the aircraft - to the left - in the opposite direction. As we started to initiate the 'left' turn - corrective action - we were queried by ATC at that time.
