Tesla infotainment system upgradeable from MCU1 to MCU2

[JACMS3]

Anyone who already upgraded from mcu1 and ap2 to mcu2 and ap3.

2017 ms100d.

Is regen the same?
Also when you are off accelerator does the car stop and go on Hold?

Or you still have to press brake pedal to Hold.

Thanks.

just curious-
do you need to prepay this upgrade for them to get parts moving? Or do you post pay like any other normal service?

Post pay

Post pay

Thanks- nothing like tying up a few grand for a Tesla “coming soon”. I’d rather get in line now and pray my MCU survives the wait.

My MX 90D went from MCU1+AP2.0 to MCU2+HW3.0/FSD. I haven’t noticed anything different regarding regen. I think the stronger regen and the “regen to brake hold stop” requires Raven upgraded front motor; I believe the permanent magnet motor in Raven cars and M3/MY doesn’t suffer efficiency loss as regen goes to 0 mph while the older induction motors lose efficiency on the final low speed regen.

Correct. Only the Raven permanent magnet motors can lock things with just the motor.

Ok I understand now.
It won't have it like model 3.

Thanks.

Thanks. Understood now.

Almost outrageous.
In Europe HW2 fellows like me (who have paid for FSD long ago) are stuck (MCU2 upgrade not available, HW3 upgrade only coming from HW2.5) and are praying that the eMMC doesn't die before (if ever) the upgrade becomes available... while in the US cars are getting AP-upgraded even without buying the FSD option.

I generally don't like to complain but it takes a lot to accept this non-sense.

I put my request in last night for my 2015 AP1 MS, received a text asking which MCU2 I wanted (with or without screen). I opted for a new screen. I haven’t had any yellowing (less concerned about that) or leaking (mostly concerned that this could develop).

Here’s hoping my current MCU can hold out for a month or 2!

Someone commented the new screen looks and feels different. More details??

I know this is a small group of people, but if anyone gets an MCU1->MCU2 upgrade who already has the Light Harmonic amp installed, please post if you are getting the loud "pop" sound on power-up as mentioned in one of the LH Amp threads. I'm just curious if it's a widespread problem with MCU2+LH, or maybe more of an isolated incident. Thanks.

@HankLloydRight Do you have MCU2 and LH amp without the pop?

And piggybacking on this question, can you provide a video showing what the pop sounds like?

interested in this as well. been waiting 6 weeks now for my parts to come in but SC said if I choose to keep my old screen they can do the upgrade now. Tying to weigh pros and cons

 

[JACMS3]

I emailed SC to-day checking warranty.

My mcu1 has 4 years warranty less month. Just took delivery in June.
I inquire about MCU2 warranty.
4 years or 2.

Make it difficult to do it if 2 years only.

 

[JACMS3]

SC got back to me.

Mcu1 I have warranty till June 2024.

Mcu2 is only 2 years from date of install.

What you guys think?
Tough decision.

Your post is a little confusing. Did you purchase a cpo?

Yes bought used. (no cpo now)
Took delivery last month June.

So I have 4 years confirmed by SC on the MCU1.
If I upgrade to MCU2 I will have only 2 years warranty.

Keep the MCU1. Let tesla keep replacing if it fails. By year 4 of the warranty there is a chance Tesla might be done with MCU1 and replace with mcu2 for free or have lost the NHTSA case and forced to redesign MCU1 with a reliable Emmc

For me, my car warranty has fewer than 9 months left, but the MCU was my biggest worry. With it replaced, I am more confident keeping my car well past 100,000 miles until the battery warranty is up.
