    So I flashed the bm3 ots stage 2 91 tune (I have catless downpipe) and everything went well did a few pulls and I was good! Tonight I went to do a pull on the freeway and got the drivetrain malf message. I turned the car off and in and it went away. I tried doing a small pull after and go it again . This happened 3-4 times. I will log tomorrow and scan the car before I turn it off and on. I read another persons post with a similar issue but his was a custom tune . Any inputs on this ? Thanks in advance

    Damn, I was getting ready to order bm3 for mine. Maybe MHD+ Android tablet is worth?

    Don't just give up. Thousands of people use BM3. I have BM3 Stage 1 OTS on 93. No issues for months. Updated OTS to December release as well.
    I don't have experience with MHD, but Twisted Tuning widely supports it. Can't be bad either.

    What brand Downpipe?

    Yeah it’s probably something simple , I still would go with bm3. Tons of people use it . I’m running a titan catless dp. The support team is working on it for me .

    that wouldn't really cause much of an issue. looks like the typical 11A605 people have been getting

    I got that code on my ots stage 2 91 but when I got drive train malf on the e30 tune that code wasn’t there . I messaged bm3 support and they said
    “Go to My maps and flash the stock tune ( no need to lock DME)

    Delete the map you had on

    Go to OTS screen and get the same fresh map.

    When flashing, press download now flash later.

    Then flash the map.”
    So far so good but we will see

    I was just about to jump into these mods, glad I saw this thread. I think I’ll wait it out! Good luck with finding the issue!
