File .stage1 or .stage2

[Alerm]

Hi
A my friend gave me a database of car tuning files, but i don't understand what software they are for. the files are of two types with the .original extension and with the .stage1 extension .
Could you tell me with which software I can try to open or write them?
thank you

With the information you have, I advise you to contact professionals, or start studying. Before the misuse of the database they have given you can give you problems. (this without knowing who these files come from, which can also cause damage if they are not good files):applouse:

is there anyone here on the site who makes good ready-made map files? I also don't really agree with retouching maps without a dyno.
do you agree?
