Are SCT Tunes SN Locked?

Are SCT custom tunes serial number locked to a specific SCT device? When I bought a bunch of stuff from my buddy, he also gave me his customer tunes but I cant load them on my Livewire. It reads SN doesnt match. ABORT!

Thanks

The strategies on your trucks might be different too. I wouldn't take a chance ending up with a dead truck for something as simple as tunes. Deleting them and getting your own would be the best route I think.

Yup any SCT tune with that has .cef on the end is serial number locked.

Any SCT tune written since 2009 is SN locked.

SCT files have two different extensions.

.ll3 and .cef

ll3 is pre 2009 and are not SN locked. Anything with a cef is SN locked

This makes sense because I still have some really old tunes from Spartan and all of those are .ll3. Thanks for the info.
