First time I took my car into SC the guy said that I had way too many previous navigation searches and trip data stored and it bogs down the cpu like crazy. He said you have no idea how much data the MCU is really storing for every mile it records in a trip, so when you have a lot saved, it's having to process a TON of info. To be honest mine wasn't even acting that badly (MCU1) at the time, but he cleared it all and it's been great since!

So I was indeed surprised that all my destinations since day one were still there. Were: indeed as I patiently deleted them all.
Don’t see directly a jump in speed but maybe you can elaborate on what in the mcu1 has gained in speed. Is it an overall feeling, the navigation map moves are smoother, Spotify connect faster,... ?
Thanks
I was experiencing white blocks in the navigation map would take seconds for it to load correctly. Sluggishness with screen window popups too.
I saw this. He has the new mcu2 and said it’s a rare occasion Tesla did it

Mine was lagging so much that the browser had completely stopped functioning all together and the trip and energy meters would only work for a few miles and then freeze up. After the reset everything work’s perfectly.
How is that possible? Do you have solid mobile coverage in your area? Maybe that is my issue. I can't tell you how many times I have had people in my car and tried "drive to..." or 'play..." only to get a look of "yeah, your car is not ready for prime time."
I doubt it. If the car has LTE, the owner is mistaken that MCU1.1 is newest. LTE upgrades are not that rare and could be bought at any service center.
MCU2 actually has lower resolution at 1080 pixels wide. Or they are referring to the IC screen that was updated years ago.
Right. It's possible his whole MCU was replaced with a newer MCU1. That would have given the car a higher res screen (compared to what would have been in the 2013) as well as the LTE modem I believe.

That’s what I was thinking. It’s highly unlikely that Tesla just randomly upgraded his MCU when people are begging Tesla to take their money to do the same thing.

Am I correct in understanding that when you get the Full Self Driving upgrade the MCU chip will also get updated to MCU2?

Is there a route to upgrade the MCU or was Elon making a false promise?

There isn't an MCU upgrade route yet, but Tesla claims it is coming in the future. However, in either case, the MCU upgrade has nothing to do with the FSD upgrade.
Ah. 13 pages for this thread just to get to the true question. You won't find the answer in all 13 pages. This remains one of the universe's greatest mysteries.
It will likely come. Just a matter when and how much. I can tell you for sure an upstage is available right now, it will just cost you like $60k and require a car swap.
