FSD hardware upgrade to HW3 or 4?

[markr1653]

I have a 2018 MX with HW2.5 with enhanced autopilot. With the price drop to $2000 for FSD, would I get the HW3 or HW4 upgrade? Also, what MCU would they upgrade to?

Thanks.

2018 MX with HW2.5

You should verify what infotainment / MCU you currently have (Software -> Additional Vehicle Information) as that will significantly impact how soon you might get FSD. Model S/X switched from Nvidia / MCU1 to Intel / MCU2 March 2018, and very few vehicles with MCU1 have gotten FSD Beta 10.69 early last year while those with MCU2 are getting the latest FSD Supervised 12.x.

Purchasing FSD Capability includes the cost of service installing FSD Computer / HW3, and your cameras should be good as you already have HW2.5. If you do have MCU1, I believe a small number of people have gotten the upgrade for free while others are happy to pay for the more responsive / faster touchscreen experience, but if your primary desire is to use FSD Supervised, you could associate it to the whole cost (I believe an additional $1,750).

What vehicle software version are you on? That will also indicate whether you have MCU1 (2022.8.10.x) or MCU2 (2023.x+ or 2024.x+). And it could also affect what version of FSD you can update to in the near term if you do purchase.

Don’t believe there is an HW4 upgrade available for any car

Yeah that's never going to happen. Elon said as much. The boards don't even have the same form factor, have different wiring and different cameras.

I have a 2019 M 3 with FSD purchased at that time. Tesla later replaced my computer with a “ Intel Atom”. ( no charge) In additional information” it does not show “ HW 2.5 or HW 3.0 . Im assuming I have HW3 now?

2019 Model 3s already came with Intel Atom (MCU2) that should be listed for "Infotainment processor" under Additional Vehicle Information. "Autopilot computer" shows "2.5 Computer" or "Full self-driving computer" (currently shown for both HW3 and HW4).
