MCU upgrade

Hi,

Recently i bought Tesla Model S 2015 year and MCU1 doesn't work properly, my screen becomes frozen after about half an hour use.

Should i replace MCU1 to MCU2 totally or just change the chip from 8G to 64G. The main question is if I do the replacement, it will work properly or the updated part should be programmed somehow to start working with the car hardware/ applications?

I wish we could. It has to be programmed by tesla to my knowledge. Physically changing the mcu is the easy part. I pulled the mcu and upgraded to lte in my old s85. Not too hard. But if y’all figure this out let me know. Tesla cheating mcu1 fsd. I hope someone figures this out!!

I also want to do it for my TMX 18. Tesla has opened its toolbox and you can buy daily or hourly access at Toolbox Isnt it possible to change it via Tesla toolbox, how would Tesla technicians do it?

I’m wondering the same. Was looking up toolbox info myself.
