    CASE Relearn?

    When I navigate to do a CASE relearn, the tab for the relearn is blank with the exception of the relearn button (screenshot attached). I don't have any of the fields that the video shows (RPM, IAC counts, etc.). I'm not sure if this is due to the video being from an earlier version of Scanner or what? When I click the button, it says "Gradually rev to fuel cutoff and release. You must then cycle the ignition for the function to complete", but nothing happens when I click OK (even revving it beyond 4K there's no fuel cutoff). Am I missing something obvious? Thanks.

    The screenshot is from a different ECU, not the one in my car, but it odes the same thing with the one in my car. Options don't change whether car is running, scan going/not going, etc.

    for the most part only GM has VCM Controls that you speak of, I can only assume you are not connected to a GM vehicle.
    It doesn't have to be perfect, it just needs to be done in two weeks...

    A wise man once said "google it"

    It's a 1999 Pontiac Trans Am, so I should be good there.

    should be there, make sure to repoll for the supported parameters and try again.

    I have a 2009 Chevrolet Express, 5.3 LMF motor and I have the same issue. Same screenshots as above, and I have no indication if you are supposed to start the relearn process before or after you hit OK on the second window. I've tried it both ways, and have no idea if I'm doing it wrong or right.

    I've got a '98 Z28, and my tab with the Crank Relearn button on it looks the same as the OP. Seems less intuitive than the version on 2.24. When I click the button, it behaves nothing like the GT500 video posted in another thread. It worked correctly in v2.24 on the same vehicle as I'm trying to use it on now.
