I'll never understand the obsession with using a specific software version. 99 percent of the time the tuning you're doing negates any calibration differences.
I have a tuned file from client car. I want to know what changes have been made by someone in a car. To find out why the engine is not working properly. The easiest way is to compare the files and see everything at once than it is to restore by hand. After that, I will make my tuning on the basis of another ori file for example.
