Hondata FlashPro for 2018-2022 Honda Accord 1.5T & 2.0T

The Hondata FlashPro for the 2018-2022 Honda Accord is the most important performance upgrade you can make for your turbocharged Accord. Whether your car is equipped with the 1.5T or the 2.0T engine, and whether you drive a manual or automatic, FlashPro gives you full control over tuning and datalogging to unlock the hidden power in your engine. While many aftermarket parts like cold air intakes and exhaust systems promise gains, the only way to extract their full potential is with proper ECU tuning—and that’s exactly what FlashPro delivers.


FlashPro includes the Windows-based FlashProManager software, which allows you to read and modify your Accord’s ECU. By connecting the FlashPro to your laptop’s USB port and your car’s OBDII diagnostic port, you gain access to live tuning, 56 starting calibrations, real-time datalogging, and stored data analysis. Best of all, the factory ECU does not need to be modified, making FlashPro a seamless and non-invasive upgrade. This system ensures your Accord can safely handle performance modifications while maximizing horsepower, torque, and drivability.


Built with advanced programming and unmatched reliability, the Hondata FlashPro grows with you as your build evolves. Whether you’re just starting out with basic bolt-ons or pushing for higher horsepower levels with extensive upgrades, FlashPro is designed to adapt. Although it is possible to use FlashPro on your own, Hondata recommends working with a professional tuner to ensure optimal results and safe calibration. FlashPro’s datalogging and live tuning capabilities make it an essential tool for extracting maximum performance from your 2018-2022 Honda Accord.


Key Features:

  • Compatible with 2018-2022 Honda Accord 1.5T and 2.0T engines
  • Works with both automatic and manual transmissions
  • Programmable ECU interface with OBDII connection
  • USB 2.0 connectivity for fast data transfer

The Hondata FlashPro for the Honda Accord is more than just a tuning device—it’s the foundation for every performance build. If you plan to modify your Accord with intakes, exhausts, or forced induction, FlashPro ensures you’ll get maximum gains with precision and reliability. For enthusiasts who want real performance, this is the first modification you should make.

Dyno Information

Accord 1.5 Turbo:
The flash pro comes with a stage 1 tune and a stage 2 tune for the 2018-2020 Accord 1.5 turbo. The tunes are designed to give 10-20% gains, making it have more power than the 2017 Civic Si. Max gains are not made at the top of the rev range but at the low end where it's needed the most. With this your Accord now has quicker acceleration available when you push the throttle pedal. Testing was done with 91 octane. 91 octane is not required but it is highly recommended by Hondata. 


Accord 2.0 Turbo:
The tune is designed to give a conservative yet exhilarating 10% improvement in performance. With this Hondata performance upgrade, your Accord will match the performance of many more expensive luxury cars. Your Accord gains anywhere from 10 to 40 hp everywhere, with the maximum gains not at the top of the rev range, but where you need it most at the low end of the rev range. Rapid acceleration is just a quick flex of the throttle pedal away. 91 or higher octane recommended.
