The Hardware Interface Requirement

Tip: If you are using a cheap "ELM327" Bluetooth dongle from eBay, version 3.8 is often more stable with these clones than the newest official releases.

- Intellectual property: Firmware, ECU images, and proprietary software components may be copyrighted; unauthorized copying or distribution is unlawful.
- Vehicle safety: Incorrect ECU flashing or improper adaptations can render a vehicle unsafe or inoperable. Always use verified firmware and follow manufacturer procedures.
