Just a question regarding a resale of an Osiris reflash. The one I purchased was originally from a G (but didn't work on my early Sedan). Can this be used for a Z? Unit might be relicensed anyway so can the one free base tune be the Z one vs the G? As long as it's made clear at the time of relicense?

Or can the reflash for the G be only used for the G (and Z for a Z) etc. ?

 

The license can be applied to Z or G. The rom (flash file) will be vehicle specific, even more than just Z or G. For example, and 04 Z flash won't work on an 06 Z.
