I have a Ford Fusion with a gearshift module (GSM) that has an older software calibration, but the hardware part number is the same as the GSM on a slightly newer Fusion. So basically two identical GSM's but one has an older software version. When I try to update it in IDS or FJDS, it refuses to update saying it is already the latest calibration.
Is there any way to force a newer calibration/strategy onto that module? I heard something about blank path programming but I wanted to hear if there's any other ways before I dig into the guts to get to the module.
