Narrative:
Approximately 29 mi east of lax on runway 25L approach. During approach (pdz 4 arrival, runway 25L), socal switched our runway to runway 25R, with a request to advise approach when we had that 'set up.' while tuning the new ILS frequency and verifying the identify/setup in the FMS, we noticed our position to the south of desired track, with aircraft heading approximately 220 degrees. We corrected back to runway 25R localizer after again verifying proper tuning. Correction heading was 260 degrees. Remainder of approach/landing uneventful.

Title: WDB CREW SETTING UP FMS FOR A RWY CHANGE, FOUND THEIR POS S OF DESIRED TRACK.
Narrative: APPROX 29 MI E OF LAX ON RWY 25L APCH. DURING APCH (PDZ 4 ARR, RWY 25L), SOCAL SWITCHED OUR RWY TO RWY 25R, WITH A REQUEST TO ADVISE APCH WHEN WE HAD THAT 'SET UP.' WHILE TUNING THE NEW ILS FREQ AND VERIFYING THE IDENT/SETUP IN THE FMS, WE NOTICED OUR POS TO THE S OF DESIRED TRACK, WITH ACFT HDG APPROX 220 DEGS. WE CORRECTED BACK TO RWY 25R LOC AFTER AGAIN VERIFYING PROPER TUNING. CORRECTION HDG WAS 260 DEGS. REMAINDER OF APCH/LNDG UNEVENTFUL.
