Disclaimer
Aces EFI is an Engineering and R&D-driven company focused on continuously adding new features and improving existing ones across our systems. However, not every update we release is a recommendation for all users to apply to their systems. The majority of updates are designed for specific features or systems, and they may not be relevant to your setup. Even updates labeled as improvements or optimizations to parameters and calibrations are often minor and may not have a noticeable impact on most applications.
That said, certain systems or applications can benefit from specific updates. We encourage you to use discretion and reach out to our team for guidance on whether an update would benefit your system.
Important Notes:
- Firmware Updates and Calibration
When you update your Handheld device to the latest firmware, it will include updated calibration files for your system. When you update your handheld, you will also need to upgrade your ECU calibration. Note that this will reset your ECU and it will need to re-learn unless you have saved your tune file first and plan to load it back in after the update is applied. - Backup Recommendations
Before upgrading your Handheld firmware, we strongly recommend backing up your tune using our USB Data Cable (AH2500) and Laptop Tuning Software in order to save your current tune and settings to your laptop.
For any questions or assistance in determining if an update is suitable for your system, feel free to contact our support team.
