I already have a tune from bama saved to my computer. My question is, if I buy a used SCT2, can I clear the old tunes and upload my tune on my own or do I need to have SCT do that?

 

As long as the file is the same format as the version of the xcal2, you should be able to do it yourself

 

Even if it is a newer version, I can just update the firmware and software right?

 

I believe the new files are LLF3 or something like that. If thats the file you have saved, your good. But I don't think you can go backwards with the firmware on the xcal. I may be wrong, but thats what I think.

 

Yeah it's an LL3 file. I'll just keep my fingers crossed and hope it works

 

if the file is an ll3 and your firmware is the newest. It will work just fine
