12593555 cal os file needed

[Doc]

As the title states I have a 05 Silverado with a Maggie on it with 2bar raring to go on the dyno. Looked all over tunefiledepot and could not find it. According to the LS1 COS manual it is the only calibration compatible with the 05 COS 3.

Thank you.

Could you use a 12592618 calibration and the matching 05120003 COS; there are a few of them on tunefiledepot?

A little more information, clarification, the truck is actually a 06 5.3 for which there was not a specific COS available to my knowledge. I've tried the12592618 calibration and the matching 05120003 COS; it works but the battery not charging symbol illuminates even though the gage and independent meter checks of the alternator say it is charging. I have tried 2004 combinations and the DIC actually says "battery not charging," and the light is lit as well. Trying to find the last known made calibration the manual says is made for the last known made COS is my last shot before pulling the instrument cluster and removing the battery symbol LED and calling it a day. TIA for anyone who might have a few minutes to see if they have the 12593555 calibration file in their library.
