My VIN is 7SAYGDEF4PA049XXX and the F in position 8 identifies the motor as "Dual Motor - Performance Model Y."
This is how we in Europe decode the VIN as there is a leaked official VIN decoder in the type certificate.
The US VIN structure is obviously not "up to speed" yet, as you are getting an "F", which is a "Wire Winding Performance Motor".
Although it is certain, that the 4D1 has a Hairpin Winding stator:
Perhaps Austin received some of the new 4D1 Performance motors and decided to just install in the LR and limit via the software?
Yes, most likely. The motor itsself doesnt need to be limited actually, but in the Long Range the Battery Power will be. A long range without boost caps at 970-980 Amps. This power is then split between the two motors. So, although the motor is not able to go to its full potential (with more Amps), we might still get a glimps at its characteristics with Scan My Tesla.
Also, you previously asked about Scan My Tesla" app, what additional details would that provide?
SMT with an Android device can log Power and Torque curves vs. Speed. which would tell us a lot about the characteristics of this Motor. All current generation motors, be it Wire Winding or Hairpin (3D1, 3D5, 3D6, 3D7) go up in power with speed until reaching around 80km/h and then they drop again. The Plaid for example is so powerful, because it holds its power pretty much steady after reaching its maximum power.
The main limiting factor in the Model 3 and Y dual motor is the 3D3 front motor as it drops in power significantly with speed, so a change there would be the biggest deal (as done with the Model S 2021 Refresh!).
Still, the 4D1 is currently the biggest wildcard and most interesting new Tesla motor out there, so any data is much appreciated!
Just to give you an example of power and torque measurements with Scan My Tesla...
This is data from when I measured one of the first MYP out of Giga Berlin (Nr.15 signed by E.M.) with the LG M50 Battery Pack and the (then) newest generation 3D6 Hairpin rear motor:
