FlashPro takes the top spot as the most crucial modification you can make. While many aftermarket parts promise instant horsepower and torque gains, realizing their full potential demands precise tuning. If you're considering other performance upgrades like a cold air intake or exhaust, FlashPro is essential to extract maximum performance from your new parts.

Hondata FlashPro allows you to tune and data log your 2017-2021 or 2022+ Civic. It includes a Windows-based software called FlashPro Manager that enables you to read and make changes to the ECU. By connecting FlashPro to your laptop's USB and the vehicle's diagnostic port, you gain access to live tuning, various calibrations, and extensive real-time and stored data logging capabilities. The factory ECU does not require modification for FlashPro to work with the 2017-2021 Civic or 2022+ Civic.

While it is possible for individuals to use this device, we recommend consulting with a professional tuner to ensure proper and safe implementation. Inexpert use can negatively impact your vehicle's performance.
