Can I build my own?

Yes, the software is open source and the hardware is commercial and easy to get.

Known issues

  • With K-Pro v2/v3 Hondata data logging (not the HonDash one) should be disabled to run HonDash
  • In K-Pro map sensor would only show up to 1.8 bar
  • Raspberry Pi 4 with old firmware could have WiFi connectivity problems while using the HDMI port, if this is happening to you please update the firmware https://www.youtube.com/watch?v=FZ2Kfg8xnBw
