I no longer have the tuner I sold it and the buyer is saying he has to buy a new license BC he says it is still married to my truck I just didn't think it would even get to that screen if it was still married to my truck.

Was told by guy that it would sit on that screen for over an hour and not do anything else so he believes it is still married to my truck

So it getting to this screen means it isn't married to another vehicle right? Image is in attachment.

Ok if it's still married it won't even begin to try and read the pcm for a new backup on another vehicle correct?

How do I unmarry tuner so I can use it on my other truck?

The diablo flex tune? Sorry new to this didn't know if that is the right one BC it says it's for e85 to 91 octane

Is there any reason why I can't install the 93 octane tune

Just bought my i2 was going to tune but only ones that show up are the mpg booster and 87 octane. I can see the 91 and 93 octane tunes but they are not highlighted and can't be touched. Was wondering what the problem may be
