Tesla Owner Successfully Upgrades Model 3 HW3 to HW4
A well-known developer in the Tesla community has independently upgraded a Model 3's hardware from HW3 to HW4. This unofficial upgrade addresses the long wait for official retrofits for older vehicles. The process involves replacing key components of the autonomous driving system, potentially enhancing the vehicle's capabilities without relying on Tesla for installation.
- HW3 to HW4 upgrade performed by an independent developer
- Improvement without official retrofit for an older Model 3
🔎 Why it matters: The HW4 hardware upgrade in a Model 3 originally with HW3 is significant due to the lack of official retrofits for older models.
📈 Upside: Allows owners to improve hardware without waiting for Tesla's official support.
📉 Risk: Unofficial installation may affect warranties or FSD system performance.
