    Default Cal Comparison on Different OS

    Hi All, I want to compare the cals from two vehicles of the same model except one is 2012 while the other is 2013. I tried to compare them but it returned an error due to different OS. Is there any way to compare cals from two vehicles? Thank you for your input.

    Manually, by hand. V8 Tune tool will have this capability but no ETA on when it will be available.

    Also be aware there are some tables/parameters that havent been mapped yet might be different between the years.

    This will probably be my #1 favorite feature of V8!!!

    If I only had one nitpick about V7 tune tool, its that you cant compare tunes of different OS's.

    Of course, do you understand the level of difficulty of comparing two different OS's (tables are in different locations)...? The complexity approaches order O(N^2).

    Add to that OS's that don't share the same table structures (early E38, late E38), but nobody cares Joe
    I'm actually not sure how Paul plans on doing this, there is a lot of catches to doing it for sure.
    I no longer monitor the forum, please either post your question or create a support ticket.

    Yes, totally understand and can only imagine the complications.

    I was going to add more detail to my original comment...then realized this exact statement and decided to KISS.

    Looking forward to it, know it's going to be a bit of a challenge.
