For the lazy:
v500
-All Fiesta ST maps are now v500 and have the new naming convention for Staged maps.
-"Enable Gear Shift Hang" toggle unchecked.
-Realtime capable tables (assortment varies)
-All of these maps are now "Simple SD" capable.
-New Traction Control default values. (feature is still disabled on OTS, can be enabled using the Accessport)
Not sure if any of this implies the maps themselves have changed. Seems like mostly updating features to be consistent with their other tunes.
