    Unable to find pcm with os 12593358 for segment swap

    I have a pcm from 2001 corvette with manual trans. I have the LS1 transplanted into a '68 c10 with a 4L60e. I would like segment swap the 4L60 info to the pcm but unable to locate the OS in the repository. Emailed HPtuners and they did not have one either. Can anyone help with this? Do I have some obscure pcm?
    os 12593358

    Thanks

    That OS is a late release, you can search that OS to find a thread or two about it. It seems that it's likely a M6 file only.
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.

    thanks for the reply. for future reference, is there some master OS list somewhere that helps identify them?

    Looks like the only tunes i have with that OS is 01 M6, 02 Z06 M6, and a 03 Z06 M6.
    I havent done much with Vettes but Can you go to a 2002 (12212156 OS) Vette with a 4L60?

    just change to a different os, one that you can segment swap. if its a swap vehicle, no need to stay tied to an odd os

    Use caution here, depending on your state emissions laws. Some states such as California are particular about operating systems and that whatever is in your PCM matches your Vehicle IN Number (VIN).
