Upgrading MCU

Upgrading MCU

Last Spring, Elon said that it would be possible to retrofit the new MCU in older cars. I have a 2017 Model S. I inquired about upgrading the MCU at my local Service Center but was told that it could not be done. Does anyone have any insight into this?

I spoke to my local service center this week and asked the same question. I was told that Tesla is "working on it". Hopefully that's true.

Oops, sorry. I was referring to the upgrade from HW 2.0 to 2.5, not the MCU.

@mike the upgrade they are working on is HW2.X to HW3 IF you pre-paid for FSD. There will not really be a 2.0 to 2.5 upgrade

~6 months before it is in all new production cars. No change to sensors. This is simple replacement of the Autopilot computer. Will be done free of charge for those who ordered full self-driving.

if we are talking about the central console MCU (nVidia Tegra 3 -> AMD) I called SC couple days ago - they said there is currently a shortage of them and recommended to call later, but did not say this is impossible.
