So from what I understand I can convert a tune from one O/S to mine by creating a script. I have found a step by step tutorial on this.

I have followed the steps and when I attempt to load the alternate calibration a warning pops up that basically says that the two operating systems do not match and No comparison will be attempted... Any help would be appreciated.

P.S. The two tunes I'm working with are both for an LLY just a differant O/S
