Practical advice for workshops
- Maintain a controlled process for ECU programming: stable 12V supply, fully charged battery or battery charger, uninterrupted power to the PC and interface, and a reliable network connection if remote authorization is required.
- Use original or high-quality ACTIA hardware and cables; cheap adapters often cause timing issues.
- Keep a library of firmware and driver versions known to work with particular vehicle vintages to roll back if updates introduce regressions.
