2021.24.28 Rolling out to MCU1/FSD MS/X

2017 MS with MCU1/FSD

First significant firmware update in over a year!

Old firmware 2020.48.37.8 (0.6% of TeslaFi Fleet AWT upgrade)
New firmware 2021.24.28 (0.4% of TeslaFi Fleet running this version)

Guessing no FSD Beta access but I'm 6 months closer than 2020.48. Lol.

Damn this is the one time I envy MCU1 folks. You get updates on V10 and I have to deal with V11 which is worse in every way.

I will cherish this win, with all my heart. Seeing that it took over a year to get this I think we'll be on V10 for a loooong time

Last I saw mine it was downloading at 66%, then it's gone.. Now the MCU is showing up to date with 2020.48.37.8. Screw this.

I saw my car (2017 MS 75) download circa 8GB of something (observed on router) on 8th Feb - so I was hoping it’d be an update. The car hasn’t reported an available update yet. Still sat on 2020.48.37.8. Ironic timing since it’s booked in for MCU2 upgrade next week!

Mine will be installed this week. lol

Maybe they rolled out this update:

Older Tesla vehicles to get UI performance boost thanks to famed video game engineer

Tesla is working with famed video game engineer John Carmack to improve the interface performance in older vehicles. Carmack is...

electrek.co

If this guy is so good and he came through with a working version, maybe all of us with MCU1 will see better performance.
It is a 1.5GB download my car just got so there must be something in it.

Just installed on my '14 P85D with MCU1. Didn't see any major feature changes but to me it's WAY faster. Web browser actually opens, owners manual opens, UI seems much quicker. Plotted a 600 mile nav trip in less than 10 seconds. Huge improvement for a legacy system (at least so far).

Your heated seat buttons still on the bottom of the main screen?

 

[Solar40]

Makes a lot of sense. I’ve flirted with the idea or wanting to upgrade it myself but I don’t want to spend that money. We shall see

Same here

Well I hope he then also takes a look at the MCU2 code, as it's becoming already laggy on the reverse camera, even on plain AP1 car like mine
And for those of you who don't read each and every threads & posts (good for you by the way, I sometimes feel I should get detox cure from TMC), the browser with Tesla Waze is also still having issues. Only the new 2022 S/X with the new "MCU3" Razen processor are doing fine with the browser.

That is what I am seeing as well.

I mean, if you really believe they'll get FSD with MCU2 + HW3... then well, okay then. lol.

Pretty sure it'll be MCU4 and AP6 before they actually accomplish FSD.

Any chance you had a look at this code yet in 2021.24.28 ? Have they streamlined it/simplified it in order to get the browser to actually work now?

I've glanced at it and looked at the bulk of files changed, but haven't examined in depth.

At first glance it doesn't seem like anything major has been changed/improved.

 

[gaswalla]

Just installed in my legacy 2012 S with the MCU1. Was hoping for charge stats. Will take snappy UI though

 

[basilray]

First drive with the update. Didn't really notice any difference or improvement in performance, but based on the release notes, there is/was no reason to expect one.

Same with my 2017 MS 100D FSD...been a long time since I received a software update

 

[BrownOuttaSpec]

Although I have upgraded to MCU2 in my MS90D I am still very curious of everyone's experience with this update since it was been over a year since the last one. Please keep posting your impressions of this update

 

[ayavner]

Just pulled the trigger, wish me luck!

I refuse to believe. Too good to be true! Anyone else confirm this wasn't just due to a temporary restart?

 

[TespaceX]

I don't think there's a definitive word on the matter but I've long voiced the opinion that while Tesla hasn't publicly nixed FSD and MCU1 the reality is that once they roll out FSD/MCU2 widely they'll find it makes more economic sense to upgrade the few remaining MCU1/FSD-paid vehicles to MCU2 rather than fork the codebase and maintain FSD code on MCU1 on an ongoing basis. Tesla sees MCU1 as 'beyond legacy'.

Personally I think Tesla will wait as long as possible before saying MCI1/FSD vehicles will be upgraded to MCU2 because every month they wait more of those vehicles either exit service or are upgraded to MCU2 by their owners, saving Tesla the expense of doing it themselves.

But I suppose we'll see.

No doubt.

Tesla still won’t replace my faulty eMMC. They acknowledge that I have a problem (as I have to reset screen occasionally due to glitches), but have been telling me they don’t have the part available—since the recall began. They say don’t worry about it since I can still drive the car.

It suppose to fix some bugs. We’ll see if they stop crashing

Not true for me. MCU1 is same as always on my 2015 S.
