FAQs

What is the difference between Hondata FlashPro and S300?

FlashPro is designed for late-model Civics, Accords, and related platforms still running the factory OBD2 ECU. It allows tuning through the stock ECU without replacing it, which makes it one of the more accessible options for modern Honda owners. The S300 is a more comprehensive engine management upgrade that replaces or works in conjunction with the factory ECU and is more commonly used on older platform builds where more extensive tuning flexibility is needed. Your chassis and engine will determine which option applies.

Do I need a tuner to use Hondata products?

Yes, in almost all cases. Hondata products allow ECU tuning, but the tune itself needs to be done by someone who knows the platform and the specific modifications on the car. Running an off-the-shelf base map is a starting point, but a proper custom tune is what makes Hondata products worthwhile. We recommend finding a tuner familiar with your platform before purchasing.
