Just an interesting fact I wanted to throw into this discussion. I just upgraded my MCU1 Tesla to 2020.48.37.1 and while I am not crazy abou the new speed indicator, or gear indicator moving to the left (it used to be on the right, and it made sense and the gear stalk is on the right), I must say the MCU1 seems to have gotten a major speed boost. I have replaced me emmc, but latest updates bogged down the MCU1 quiet a bit, while this latest one seems to have lifted the curse! This might be my last update I accept for a long while, as long as it doesn't crash often or kill the touch screen. Crossing my fingers (and refusing any more updates for now).
