Research and development takes time and money. Since it is my goal to keep this project opensource, if you find this project useful, please consider donating.

Software

Windows

HondaECU for Windows requires the libusbK driver. Download Zadig and use it to install the libusbK driver. There is a usage guide on the Zadig website if you need help using it. Once libusbK is installed for your FTDI device, download the latest release of HondaECU.exe.

Hardware

The easiest way to talk to the ECU via the k-line is a USB to serial (TTL) converter, and a serial to k-line converter. This code assumes you are using a FTDI based USB to serial converter. For the serial to k-line converter, I recommend the schematic below that uses optocouplers to keep the bike power isolated from your electronics.

Bench Harness

If you make a bench harness to work with your ECU you will need a 2.5 amp power supply. The ECU will power-up with a 2.0 amp power supply but transfer rates will be slow and you will get CRC errors.
