    Default Need stock 2008 TBSS file

    I'm searching for a 2008 tbss file that I can put into an e67 ecm I currently have. OS 12620193 is whats in it at the moment. Is there such a thing available? I have read this setup won't run discrete fans properly, is that true?

    The only 08 TBSS OS I've seen is 12618164 (from GM). I've attached my personal 08 TBSS file, it has the latest GM updates I pulled back in 2013, just checked and no further updates. You can indeed run efans, you either need to use another software platform to update certain parameters or find them via .cax. PCMofNC has made a patched file available in EFILive format that has the efan parameters adjusted to work properly.

    Not sure what that OS is from, you'd have to see if it's compatible with 12618164 otherwise you may brick the E67. I've advise starting with a fresh GM SPS flash to make sure the slave CPU is updated properly.
