Hello, first off, I really appreciate all the hard work you have put into this! Looking forward to being able to tune from Linux.

10 years ago I used a Windows laptop and ECUFlash to read the ROM from my ECU. There were no definitions available at the time, so it didn't progress further.

I've tried multiple protocols and multiple scenarios of turning off the ignition, testing different protocols, and so far not able to read from the OBD2 port.

What info or tests can I supply to assist getting this working?

Details:
  • 2014 Subaru Forester Premium 2.5i CVT
    Linux Mint Kernel: 5.15.0-143-generic x86_64 bits
    Tactrix 2.0 connector
    FastECU 0.1.0-beta.4
    Error: Serial Port unavailable
ROM Details:
  • Memory Model: SH72531
    Internal ID String: EA1M500BFM5
    ECU ID: 22765AE220
    H4NA PZEV CVT
    Copr.DENSO2012
    BSW_12CYH4N Ver.1.30r1

Some clarification. I should have proof read my message.
  • I previously read the ECU ROM using ECU Flash and the ROM definition was recently posted.
  • I am trying to re-read the ECU ROM using Fast ECU as a test and it has not worked yet.
  • I tested with and without the SD card inserted for Tactrix OP logging, as some mentioned connectivity issues with SD card inserted.
