I have a 2016 X P90D with AP1. Aside from a more responsive screen, is there anything I get from upgrading to MCU2? I guess I could get Netflix and games. But nothing related to visualizations or AP since my AP is 1. And I’d lose FM and XM. Anyone else done this? Thanks.

Hi @elguapo ,

We installed it in my wife's 2015 S 85 D with AP1.
It works great and drives great.
She loves the car.
I did not want her to deal with the probability of a failing MCU or Emmc...

Very Happy,

Shawn

Hi @Merrill ,

We are not sophisticated music consumers...
We knew going in that we would lose the FM radio.
We do not use USB music.
We are happy with the streaming music available in MCU2.
We do not listen to sporting events on any radio.

Thanks Shawn, my Model X needs either the chip or trying to decide if I should pay for the MCU upgrade.

@ShawnA Thanks! Does it actually bring any functionality other than a faster touchscreen response?

got mine done today. Altho it’s prob worth it , IMO it’s overhyped. I heard the phrases “like a whole new car” and no it’s nowhere near that. It’s just simply more responsive. There are a few new toggles avail in the drive options which I’ll look at again later. Just nothing to write home about.
That said I lost some functionality. I can no longer close any doors or trunk from the fob because the car sensors think there’s something obstructing the sides

But it is exactly like getting a whole new car, you have to configure everything again. In all seriousness, though, I think it really depends how much time you spend messing with the MCU.

I just had the upgrade done. I didn't not have to reconfigure anything. All of my previous settings were transferred to my MCU2 update.

I’ve got my upgrade scheduled in 10 days. 2016 P90. Got the email that the parts have arrived.

What I’m most looking forward to is the instrument cluster starting up quickly. My IC takes a while to load up, even after only being away for a few minutes. Of course it seems to always happen when someone is waiting for my spot or something and those moments seem like eternity.

I’ve read that the upgrade will fix this.

I ended up replying to the service text, saying how crazy it was that I have been waiting almost 4 months, and they called me and said they called another service center that had the part in stock, and were getting it from them. ...so maybe suggest that to your service center?

I did not have to configure anything again because they did a back-up of your settings before swapping out the mcu. To me it does feel like a new car because the mcu is what you use all the time, change radio station, navigation, texting, voice control... especially voice control since on mcu1 it was so slow you didn't know when to start to speak so the system would recognize it. Maps loaded so slowly that I drove faster than the map could load.

Outside a bubble
Just wanted to put this out there, as I didn't see anything else posted when I searched. I recently had my 2017 Model X (MCU 1, HW 2) upgraded to MCU 2 and HW 3. After getting my car back, I noticed my audio didn't sound "premium" any more (less bass, not as loud on the same volume setting, etc). I noticed my EQ settings now maxed out at 8 instead of 12. I'm coming up on 50k miles so I decided to have a mobile service appointment scheduled to check it out just in case.

Mobile service was out today and they confirmed my suspicion. After the MCU and HW upgrade, my audio was somehow set back to "Base" instead of Premium. The EQ settings didn't matter (all new cars with MCU 2 have EQ settings that max out at 8, whether its Base or Premium) but the sound in my car was in fact not as good as when I dropped it off. The mobile tech verified my concern and is escalating it to engineering for a solution.

Hope this helps someone out that may have had the same suspicion but never acted on it!
The interface changed with the MCU2 - its part of the Intel Atom processor

Even with AP1? My sense is the changes are far less noticeable with an AP1 car.

Sorry restarting this thread again- does anyone know if the MCU upgrade for $1500 is supposed to include new touch screens or instrument cluster?

2016 MS on AP1/MCU1 - trying to determine if it's worth upgrade to MCU2. Knock on wood so far the MCU1 has been holding up well.

Also does anyone know memory capacity of eMMC flashcard provided in the $1500 upgrade versus the NHTSA recall retrofit of the 8gb mmc?
