Telsa HW3 to HW4 Upgrade is hard
A facebook post discussing the HW3 to HW4 upgrade and how painful it is explaining why Tesla will never do it officially. No link or background so take it for what its worth.
For you HW3 guys, would you try the upgrade or just trade up to a HW4 car?
The first successful conversion of a Hardware 3 Tesla to Hardware 4 is complete, with a 2022 Model 3 now running FSD Supervised v14 on upgraded hardware. The work was carried out independently by enthusiasts rather than Tesla, and it required considerably more than swapping a computer. Alongside the HW4 unit itself, the project involved ECU modifications, camera adapters, different camera mounts, headliner modifications, and a full windshield replacement. The builder described the process as a nightmare after the early optimism that followed the initial attempt, when it appeared the camera cabling could be reused and the job might prove straightforward. Some refinement work remains outstanding. The achievement is genuine, demonstrating that HW3 vehicles can technically run the newest software stack given enough effort. What it also demonstrates is why Tesla is unlikely to offer this as a paid upgrade. A retrofit requiring windshield replacement and interior disassembly across roughly four million vehicles presents a service burden that would be difficult to justify commercially.
