Confirmed. I'm almost ready to call this a pattern.
Summary:
It appears likely that at some point in 2019, AWD non-P vehicles started being equipped with MOSFET-LC (1120990) motors, while Performance and Performance-capable vehicles have continued to be equipped with 1120980 motors (which has been referred to in one place on someone's service document as a "MOSFET-HC" motor). So maybe one is high current and one is low current. This is sort of supported by there being two different remanufactured units in the part catalog, an "840" and a "630" (the lower "current" one (no "A" (amps) unit is in the catalog) is no longer listed).
To disprove this pattern, we'd have to find a Performance vehicle with a 1120990 motor. So far, no luck.
Perhaps this is Tesla's sane answer to the "Performance drive units are lot sorted for highest sigma output " situation they had up until that point (x/2019), which most people have doubted in these forums, but perhaps was actually happening (the main reason it was doubted here was that no one does things that way)?
Whatever would
@Knightshade &
@StealthP3D say?
