Polestar mode

B-series (mild hybrid): Polestar install is an ECM and TCM software. The mild-hybrids appear to have a newer generation of Aisin transmission and AWD system, where the TCM has (more?) control over the AWD operation. No DEM flash with Polestar install, but the AWD appears to be within the control of the TCM that gets flashed. For these changing config does not appear to have any effect "enabling" any present programming. (Note XC40 seems to be an outlier, uses the "old" style DEM even on B-series)

I flashed 02 Polestar Optimization on my '24 XC60 (B5 mild hybrid) and can confirm that a) Polestar Engineered mode now shows as an option in AAOS driver controls next to offroad mode, and b) it has a noticeable effect on shift points when active. RPM generally stays higher through acceleration and deceleration. Polestar mode also disables auto-engine stop which is nice because I haven't found any other way to disable it.
