    Default Merging cax files

    What do you do if you have two different .cax files with the same filename...?

    For example: 12202088.cax for transient fuel and 12202088.cax for lean cruise.

    The 'data' portions of the two files will need to be combined by someone if you want both.

    Mines not in that directory, only .calz files :( Been wanting to have a look at one of these for a while

    I merged the transient fuel and the lean cruise patches for 12202088...

    I had to rename lean cruise to B9100.

    I see both transient fuel and lean cruise show up on my 12202088.

    Let me know if this looks incorrect...

    While not wanting to sound like a total geek......

    Can the .cax file be edited with "vi" etc under *nix ? The main issue is if the .cax file needs the <CR><LF> at the end of each line or if it will be fine with just a <CR>.

    Simon,

    You are correct in saying that the file has to have crlf line endings since it is a "DOS" file.

    vi on linux (rhel4.7) seems to treat the file correctly, it seems to use the existing line endings (crlf) on any newlines you type in.

    I find that the .cax files have to be in the folder C:\Program Files\EFILive\V7.5\Calibrations otherwise the tunetool doesn't seem to pick them up.

    Is this only for gas tune files, or would it work for Durmax/Allison files as well?

    Anything, Gas, Diesel, Trans.
    Just match up the .cax OS number with the .calz OS number and you should be all set.
    Joe, I thought the .cax files needed to be in the directory the .calz file was in, I'll ask Paul to clarify that. To me it would make sense to keep them with the .calz file rather than create clutter in the Calibration root directory.

    Cheers,
    Ross

    Cool... I guess the hard part is knowing what to add and how. Problem is I can't imagine how anyone outside of EFILive or otherwise in possesion of intamate knowledge of GM's mappings could possibly do anything with it. I can think of what I'd like to do with it (if it's possible), but there's no way in you-know-where that I would have a chance of figuring it out...
