    Default WTF....i want a COS5

    12221588 OS in my 02Z06 ETC car....i want to run the COS 5 but it appears only cos3 is available for my car....having a helluva time tuning out the bucking with my 235 243 620 623 111+3 cam in my stock cube 346 with the stock OS
    Any ways around this so I can run the Cos5?

    Your available options:
    - copy all your tables to a 2002 ETC/M6 12212156 file (you have ETC and M6); get your Z06 completely/correctly running on this, and then the transition to COS5 is simple.
    - copy all your tables directly to a COS5 file.

    The first option is more flexible as it lets you troubleshoot any transition problems without having to blame COS5.

    To copy tables, since the OS are different, you would have to open two instances of the tunetool (one on your old file, one on your new file) and use copy-with-labels and paste-with-labels to copy each table (table-by-table)... it is tedious (takes about 2 hours), but at present that's all you have available... spend time and do this carefully.

    Yes, that would be the one.

    Copy your tables over, table-by-table, save to file... do full flash, read it back and save to new file... make sure car runs same as old OS.

    Then follow the COS Update tutorial (located under the folder C:\Program Files\EFILive\V7.5\Doc)...
    also see the COS5 thread, there's a few extra things you have to do (it's a long read, so look at the summary at the end):

    COS5:
    showthread.php?t=2599
    showthread.php?t=2270

    Note: if your EFILive software is at build 84, then you have the COS5 files already, you do not have to get them from the thread.

    From scantool or tunetool do Help->About and see which build it says.

    I don't remember, do you have FlashScan V2 or FlashScan V1...?

    For updating, if you have the build or a newer one than what is listed on the main EFILive.com download page (build 72) then go go into the start menu under the EFILive program folder, click Tools then Check for Updates. Have to do this for both V7.5 and V8 (if you have a FS V2).

    +1 what Erik said.

    If you have older V2 bootblock/firmware you will have to update those...

    but first let us know what scantool/tunetool build version you're currently at.
