FSD & MCU1 (HW2.0) on old 2016/17 models?

Out of curiosity, what is Tesla planning to do in this situation? I'm going to plunk down 3700 today to upgrade my EAP to FSD. I'm currently rocking HW2 and MCU1. I know I get free HW3 install. Tesla mentioned before if HW3 isn't sufficient it will upgrade paid HW3 users (obviously might be while!). How they going to do that on a late 2016/early 2017 model S? Also if FSD is actually approved in Europe, will my car be eligible? The MCU1 unit is slow as hell. I know it only does visualisations not the actual work, but even so, it must be a struggle right? Keeping this Telsa forever btw. I do 1300kwh a month of free charging due to living next to a tesla station so will just replace bit after bit!

You’d be in the same boat as anyone else with HW3. If you believe Tesla actually plans to do any sort of upgrade, there is no reason to believe that would exclude your car. I personally will believe it when I see it. I don’t think your MCU version has any impact on this. I think you can still upgrade to MCU2, but I don’t think that helps with anything here except for a sluggish screen.

Can you still update EAP to FSD? I thought that had to be purchased before February 14? I have a 2017 S with HW3 & paid FSD. I'm wondering what the future is for HW3.l? I'm toyng with a $60,000 Cybertruck & transfer my FSD to it.

Following this also to find out if you were able to upgrade EAP to FSD (after Feb 14 2026)? If so, that is very interesting for my used car search.

I am in Europe so I think different timing to you guys.
