    Can you copy paste the output_3.obd here? If it's long then 100 lines is enough.

    Usually such problem is caused by Chinese buggy OBD-II chips that do not handle auto-detection correctly. In such cases you'll need to set the protocol from Settings > Export settings > OBD-II protocol

    Unfortunately only ELM327 command set is supported by RaceChrono. Apparently this reader has ELM323 chip that may have different command set than the ELM327. Looks like the reader fails to recognise the initialisation commands send by RaceChrono.
  • So elm323 can not use?

    work elm323 for harry's lap timer but i like racechrono..

    you can make elm323 work?

    Yes, I can probably make it work. Please give me the reader brand and model, also a link where I can purchase it.

    OK. I'm sure any ELM 323 based reader will work the same way. The ELM323 chip is missing the AT SP command that is used by RaceChrono. I will try to make a fix for next version. Seems straightforward fix, but testing is a bit tricky if I cannot find the device.
  • thanks aol

    i'm waiting

  • When will the upgrade?
  • I'm currently finishing ongoing tasks and fixing bugs for the next beta version. Will take some time more to make sure it's top quality.
  • Fixed in v4.8 beta 1 released today, please test
  • do not update file
  • Well it doesn't unless you join the beta group:
    http://www.racechrono.com/forum/#/discussion/832/beta-group

    Please follow the instructions carefully. When successfully joined, you'll receive the new version through the Play Store.
  • it is same... good connect but do not working..

    Which version is it? I think you failed to update. Please confirm and take a screenshot from the main screen. It will say "v4.8.0 beta 1" when updated successfully to the beta. Notice you need to join the Google+ group with same Google account you're using in your phone, AND you need to press the opt-in links.

    Thank you for the screenshots! My fix does not work then, I was sure it would work... I need to figure out why. I will create new beta once I find out the problem.
  • Please, can you make another test with v4.8.0 beta 1, try recording 5 minutes and make sure the OBD-II reader is connected? Then send the whole session (with all channel_* files etc) to me at tracks(at)racechrono.com . I'm really having hard time figuring out why it does not work.
  • thanks aol

  • Thank you for your consideration.

    Thank you for your patience. It's not easy fix as I cannot purchase the OBD-II reader for testing... Let's try couple of iterations like this, I hope you don't mind.

    Unfortunately that session is older an session recorded two weeks ago 2016/10/6 21:38. The date is in the folder name "session_20161006_2138". Please send me a session recorded with v4.8.0 beta 1.
  • session new track(3) file is v4.8.0 beta 1 recorded

  • Can you zip the session folder like the other one please? .rcz does not contain debug output
  • okey

  • The log already looks different, probably much closer to working. Basically the initialisation goes OK, but the channels requested return no data.

    Was your car running when recorded? It needs to be, or no data. Also what have you selected for "Fast channels" and "Slow channels"? Can you try selecting only "RPM" as fast channels, and nothing as slow channels? Then try recording with car running.

    ELM323 v2.2
