I received my SCT X4 yesterday and got my tunes emailed to me today from 5 star. I am going through the directions the X4 came with and updated the X4 then put all the drivers etc. onto my laptop and put the custom tunes on the X4. I want to load the custom tunes on my truck tonight but want to make sure I save my stock info in case I have to go back to stock. The directions dont tell you how to save your stock info and tech support is closed. Can anyone help me with this quick or should I wait until tech service opens tomorrow? Thanks

 

When you begin the programming of the email tunes, the device will automatically save the stock tune first, it all comes up on screen.

Ok so just plug it in and go through the process, does it say stock tune with the 3 performance tunes so I can find it later?

I'm being overly concerned because I'm afraid I didn't download the tunes correctly and if I load a corrupt tune on my truck I need to be able to return to stock immediately...

 

Plug it in and look at the screen when you point it to the programming portion, your custom tunes will appear on screen if they are loaded properly, will look something like this.

Which one is your stock tune? Or is it on the next page?

 

Stock tune is held in memory and not shown on screen.

How do you return to Stock?

 

When you plug the programmer in next time it will give you the option, you really should read the manual and FAQ on their website.

I read everything it came with in the box including FAQ, it didn't say anything about saving stock tune or re-installing stock tune. I did not look on their website...

 

Thanks for the help, I appreciate it.
