Custom OS#5

[joecar]

Check to see if you have these files:

02020005:
C:\Program Files\EFILive\V7.5\Calibrations\LS1B\Custom\020200 05.cal
My Documents\EFILive\V7.5\Bins\Custom OS\02020005.tun

01290005:
C:\Program Files\EFILive\V7.5\Calibrations\LS1B\Custom\012900 05.cal
My Documents\EFILive\V7.5\Bins\Custom OS\01290005.tun

If you have a later build of EFILive software, you should already have those files;
If you don't have them, then get them from here: showpost.php?p=50208&postcount=218

Note that the two .tun files above are "empty" (they contain no calibration data);
you have to full flash the COS5 .tun file, and then cal only flash from your running
12212156 (for 02020005) or 12225074 (for 01290005) file;

then read back the tune, fix the out-of-range cells, and save as a new file...
this is now your first working file (i.e. from now on, edit and flash from this or its children).


If you're starting from OS's other than 12212156 or 12225074, then follow these steps first:

If your 1999 F-body .tun file is stock, www.holdencrazy.com has a 1999 F-body->12212156 migration tune file;

If your 2001 F-body .tun file is stock, then no need to copy tables, just go straight to 12212156 (see full flash below);

Otherwise, you must copy each table from old file to new file (use copy-with-labels and paste-with-labels);

Then full flash in the new 12212156/12225074 file, make sure the vehicle runs correctly before flashing in COS5.


COS5 summary notes are attached.

You will have to read the rather long COS5 thread if you want to get the full benefits of COS5.

Thanks.
