mcu1 replacement

    Can all data/setting be saved by service during MCU replacement?

    A technical question for you technical geeks: To fix my ongoing CPU1 issues, local Tesla service just replaced my existing MCU1 with a new (i.e. recon) MCU1.

Since these two are so closely married and I have...
