Hi,

I have purchased a supercharger that came with 2 tunes already loaded in the X3, now I may want to go out and having my car dynotuned but I don't want to loose those original tunes.

How can I copy back those "already installed" tunes back into my PC so I can replace them after with the new ones.

So like that if I'm not happy with the new tunes I can always go back to my original "safe" tunes.

Thanks,

 

You can't pull the tunes off the X3 only load them and save your stock (manufacturer tune).

You have 3 spots for tunes so if you get a dyno tune don't have them overwrite the existing 2 tunes.

 

The problem is that normally I alway have 2 tunes, one 91 and one 93 octane. Because sometimes here you can not find any 93, it's limited toa few gas station I always like to have my 91 in those cases.

Regards,

 

Keep the one safest tune and then load the two new ones.

 

You're right, I should keep my 91 current as my safe and get 2 new ones (91 and 93).

Thanks,
