    Default Can cax alter the parameters without changing anything?

    I downloaded a cax file the other day and now when I just open a tun file that's been running good I get several parameters that are out of range. And on top of that there are several values that just don't look right now even though I changed nothing.

    So is it possible the cax file can alter values on it's own?

    When I rename the cax file the errors go away and the values look normal, so I have to question which one is correct..with or without the cax file.

    I got an Email stating there was a reply yet I don't see one!

    Anyway, what do I trust, with or without the cax file?

    Attached is the cax file renamed with .txt to upload and the tun file.

    You'd have to discuss the "out of range" parameters with the author of the cax file.
    There will be problems with existing cals if the cax file defines calibrations in duplicate memory locations as those existing cals.

    Lee, that was my bad. Rename this to your OS.
    (Your OS only shared some similarities to 12212156) The fuel transient tables were a slightly different address causing the out of range values to show.
    Efilive would have shown these values as out of range but would not have altered the values. As long as you didnt try to bring these values back into range there will be no issues. If you did go back to your previous tune .
