Hondata

4.7.3 (4 July 2026)

• Firmware updated to version 284
• [FL5] Added support for 2026 FL5 66V-A11
• [DE5] Added support for Mexico Integra Type S 6PV-X03

The US 2026 FL5 with A11 ECU uses a different CAN gateway than the US 2023-2025 FL5. The ECU, CAN gateway and vehicle have to be matched, otherwise there are errors. eg you cannot use a 2024 ECU in a 2026. You do not need the Hondata CAN Bridge on any of the the US FLK5 including the 2026.
