What it solves

This project provides a toolkit for interacting with a Tesla vehicle's CAN bus to enable or restore specific Autopilot and Full Self-Driving (FSD) features. It allows users to bypass regional restrictions, recover Traffic Light and Stop Sign Control (TLSSC) on vehicles that have been "VIN-banned" by Tesla, and reduce the frequency of "hands-on" steering wheel nags.

How it works

The software runs on either a Flipper Zero (with a CAN bus add-on) or an ESP32 microcontroller. It connects to the car's CAN bus (typically via the X179 port) and performs bit manipulation on specific CAN IDs to spoof configurations or replay healthy bus broadcasts. For example, it can modify UI_autopilotControl to unlock FSD or use a "read-modify-retransmit" approach on CAN ID 0x331 to restore TLSSC on banned cars. It also includes a "Nag Killer" that echoes steering torque signals with organic variation to satisfy the car's hands-on detection system.

Who it’s for

Tesla owners (Model 3, Y, S, and X) across various hardware versions (HW1 through HW4) who want to customize their Autopilot experience, recover lost features on banned vehicles, or access detailed live vehicle diagnostics.

Highlights

• FSD & TLSSC Recovery: Bypasses region-gates and restores stop sign/traffic light control for VIN-banned vehicles.
• Nag Killer: Uses a random-walk PRNG to simulate organic steering torque, reducing the need for manual steering inputs.
• Live Diagnostics: Provides a read-only dashboard for battery management system (BMS) data, energy consumption, and DAS status.
• Hardware Flexibility: Supports Flipper Zero and several low-cost ESP32 boards (starting at $14) with a web-based flasher for easy installation.
• GTW Config Replay: Masks modified gateway frames by replaying learned-healthy broadcasts to other on-bus ECUs.
