Tesla MCU1 to MCU2 Upgrade with FSD

[@HalfIdeas]

A couple follow-up notes. If you upgrade the MCU, please delete all of your settings and logout of Spotify, TuneIn. Unpair your phone and wipe the contacts from the car. The reason for this is that the MCU may get re-sold by Tesla and you don't want your data on the device after the upgrade. Not a huge deal but I did end up having to reset my Spotify password. A couple folks asked and, YES the screen gets replaced. Both the smaller dash screen and the main screen. After a few months, I'm still very happy with the upgrade. Highly recommend and the FSD updates just keep on coming.

[@kamran5]

Only Tesla can install Tesla parts Especially mcu I see some guy here on KZbin complaining that he couldn't do much Still to be on the safe side I will delete whatever I can

[@rahimdiggler6640]

Than you for that. I've been looking for hours for someone to go through the actual experience, thank you.

[@HalfIdeas]

No problem! Thanks for checking it out.

[@henrycruz45cal]

Thanks for the warning about the garage door

[@Chrisb8s]

I do hope that you get this question. My MCU is dying.. so I need to either get the MCU upgrade or replace with same. I am leaning towards MCU2, because I would like the faster graphics as well as better music and ability quickly find music or stations. here is my question. Tesla is telling me that the Screen is not a part of the MCU, so if the screen also needs replacement, mine most likely does not.. it is $3599.. or that is the quote I recieved. did you get a new screen with your update or would you even notice?

[@HalfIdeas]

I did get a new screen as part of the MCU update (March 2020). The technician told me that they had to upgrade both screens, the speedometer screen and the main screen as part of the upgrade. The explanation was that the older screens have computer components that are replaced by the newer MCU. Based on my experience I would think that you only need to upgrade the MCU... maybe you'll also get a new screen included like I did for free? No guarantee there but that was my experience and what my technician told me.

[@efficientfuture]

@@HalfIdeas I have a Tesla model X 2016. Can I upgrade from AP1 to AP2? I bought it used and I'm used to my 2020 Tesla model 3.

[@repoloTUNING]

Next week my model s mcu1 and ap2.0 will install mcu2 and FSD. It is one of the first in Spain. I saw that your screen had yellow edges and when I changed the mcu I no longer had them. Have they changed the screen with the mcu or repaired it?

[@HalfIdeas]

Yes. When the upgrade was done the screens were also replaced as part of the process... I didn't pay extra for the screens.

[@acastro1086]

Did you have ECU with 2.0 hardware or 2.5? 2.0 for cars purchased Oct 2016 to Aug 2017 and 3.0 were cars purchased Aug 2017 to April 2019. I ask because if you had 2.0 you had black and white cameras and i was wondering how sentry mode would work?

[@HalfIdeas]

I had AP2.5. This was a Nov 2017 Model S.

[@noahc6246]

I also heard MCU2 adds a better audio experience as well over MCU 1 is this true?

[@HalfIdeas]

I didn't feel that the audio experience was better/worse. The big difference is that AM/FM radio went away. They now have an add-on that brings AM/FM back with the MCU upgrade so really the audio doesn't feel much different.

[@saudforyou]

Upgraded from AP2.5?

[@chrisashley1550]

Did mcu2 improve the stereo sound any?

[@HalfIdeas]

Not that I noticed. I lost AM/FM radio that was the biggest obvious sound delta. The actual sound quality was pretty good and has stayed pretty good. I'm not an audiophile so perhaps there's a delta but it wasn't obvious to me.

[@stevenrobidas]

Do they replace the screen as well? I thought they didn't but it looked like your yellow border went away. And how seamless is the tunein FM channels? What kind of lag do you get before it starts to play?

[@HalfIdeas]

Yes. they replace both the main screen and also the smaller dash screen according to the tech. TuneIn FM is good but not perfect lag seems to depend but usually just a few seconds. I have found that I either listen to spotify/podcasts so I only use FM for a few things. Haven't missed it so far.

[@FlightStreaming_]

hey I'm not sure if you answered this already but how much was the labor?

[@HalfIdeas]

MCU upgrade was $2500, no additional labor. This was included in that price. The FSD upgrade was something that Tesla previously offered to people who didn't initially purchase and this included the FSD computer, that price also included labor and was around $6-7K.

[@FlightStreaming_]

@@HalfIdeas thanks for the quick response.

[@zackbaldasaro9412]

When you upgraded your MCU2, did it come with the FSD chip, or did you purchase the FSD upgrade separately?

[@HalfIdeas]

FSD was purchased separately. The 2017 Tesla had what was called "Enhanced Autopilot" and this was upgradable to FSD before the MCU upgrade was available.

[@efficientfuture]

So we can upgrade the AP computer 1 to AP computer 2?

[@HalfIdeas]

For certain model year Teslas - yes. If the car has the right cameras it may be able to be upgraded. All very early model 3's can be upgraded and some model S's & X's with VIN's from 2016-2017. You may need to check with your service center.

[@ElMistroFeroz]

Yeah $2,500 for video gaming and movie-watching is a tough sell. The web browsing is great, but you can also get an ipad or android tablet for much less.

[@MalicetheOmega]

Did you get any discount for doing both at once? I just traded in my 2013 model S with MCU2 unit for a 2016 and didn't realize this one didn't have it. Trying to figure out if I want try to save for the upgrade again

[@james5360]

Tesla will do the upgrade for free as the feds ordered the todo as so any were failing.

[@MalicetheOmega]

@@james5360 they will definitely not do it for free. I paid 1600 to get my 13 Model S done less than a year ago. They are trying to charge me 2500 for the 16 Model S

[@ambernadeau4407]

Did you get that updated at Dedham, MA Tesla SC?

[@HalfIdeas]

Good eye! Yes.

[@kamran5]

Did they install new 17" screen too? or used the older screen? What about the cameras? are they new? How is the sentry mode? Can you record now?

[@kamran5]

Greg Raiz, I have 2017 MCU1 and I can't record anything in sentry mode. I contacted Tesla to schedule my hw3 upgrade which I had purchased last year

[@kamran5]

@@HalfIdeas getting it all done June 2nd at Dedham SC Speed alone will be worth it, as my cousin 2020 Tesla loads waze a lot faster, mine takes forever lol

[@nicalinda89]

I have an early 2017 model s built with FSD and 2.0. Will upgrading to MCU2 give me all those features and sentry mode?or I need to upgrade the hardware to HW3?

[@kamran5]

Greg Raiz did you lose FM radio?

[@kamran5]

@@HalfIdeas Have you noticed that connection speed any faster than MCU1, like I do listen to Tunein and sometime it just gets stuck lol, and won't connect to the station, or sometime if you take a long phone call and come back, the wheel keeps spinning again, Thanks for answering all these questions

[@MrDavid949]

Is this a free upgrade for cars that were purchased with full self driving?

[@HalfIdeas]

The FSD computer is a free upgrade if your car was purchased with Full Self Driving. The MCU upgrade is not free.

[@MrDavid949]

@@HalfIdeas Thanks for the quick reply. I thought that the newest FSD computer required MCU2, but from your comment above it sounds like that is not the case...

[@HalfIdeas]

MrDavid949 I have heard that the MCU upgrade was initially required but I don’t think that is true anymore. I’m not 100% on this but I think it’s correct.

[@Enjoy_urLife]

Thanks for this review; My appointment is this Monday. I will head down to my garage and clear out, and/or reset to factory settings this evening. My only question is, Does your Tesla CPU pair with your current garage system?

[@HalfIdeas]

Yes. My old MCU and the new MCU have had no issues pairing with my garage door. The Model S is compatible with HomeLink garage doors and I've been able to pair it with two different garage doors at home and one at work. On a Model3 I believe the HomeLink garage door is an extra charge add-on.

[@catchychazz]

Do you still have free premium connectivity from Tesla even after the MCU upgrade?

[@HalfIdeas]

Yes. No change in my connectivity after the upgrade.

[@VGMusicMagic]

I am waiting for my AP 2.0 Model X upgrade. Did they leave your unlimited premium connectivity as it was after the upgrade?

[@kamran5]

@@HalfIdeas thanks for answering this... Was going to ask this too

[@HalfIdeas]

Yes. Unlimited connectivity is still working.

[@danielonn2002]

how much to upgrade

[@HalfIdeas]

It's $2500 to upgrade the MCU. The invoice is on-screen at 1:28. I also upgraded the car to FSD, the price for that is listed in your app and changes all the time.

[@raysanders6723]

Really great and informative video thanks

[@nogradient]

Great run down

[@bob8606]

I bought my MS in 2016 with FSD. So far no word from Tesla on the upgrade to my AP 2 with a new FSD computer. Any one have any experience on this? Will MCU2 come with the new FSD computer?

[@HalfIdeas]

I had to request the upgrade via the service section of the app. As soon as I did that it kicked off the process.

[@bob8606]

@@HalfIdeas Thanks. I put in a request under Service/Other. I do have an appointment next week. I'm debating on the MCU upgrade. My car is already 4 years old. $2,500 is kind of high.

[@HalfIdeas]

@@bob8606 It's certainly not cheap but I have felt that the MCU upgrade has given the car more features and I'm getting more regular software upgrades for new features than I was before.

[@bob8606]

@@HalfIdeas If I get the MCU upgrade do they replace the screen as well, or is only the brains behind the screen?

[@HalfIdeas]

Leif they replace both the main screen and the dash screen too. AFAIK

[@raroque12]

Do you have to pay if you paid full price for FSD? Paid full price for FSD since I got the MCU1 I did not get the Beta button. Should the upgrade be free if you paid full already for FSD?

[@HalfIdeas]

I believe the upgrade to the FSD computer is free however the new MCU is a paid upgrade. I upgraded both the MCU and the FSD computer in one go however I think that you are allowed to just upgrade the FSD computer (for free if you purchased FSD) without upgrading the MCU. More info from Tesla here: www.tesla.com/support/full-self-driving-computer

[@james5360]

You might want to contact Tesla as the feds ordered Tesla to upgrade to the mcu2 at Teslas cost. You might be able to get reimbursed. Food for thought

[@HalfIdeas]

Great comment. Tesla has issued a recall for old 8Mb MCU Chips. This isn't the same as upgrading the MCU and I wouldn't be eligible but if you upgraded because your MCU died then you may be. Detail from Tesla: www.tesla.com/support/8gb-emmc-recall-frequently-asked-questions

[@robertsemple299]

My old MCU will not get resold because I will be retaining it. It's my property.

[@gregorheinrich]

Thanks - you can increase the speed of a slow mcu 1 also with a factory reset. See kzbin.info/www/bejne/p5u8eoFurryZr9k
