I have MPVI Pro and HPT Version 2.22 for my own personal use on 2 vehicles. Many of my older tunes were lost when a laptop died. I have found one of my older tunes on a desktop at my work that l want to use to make changes in transmission because the more recent tunes extracted from this vehicle are missing some information that l want to modify.
The tunes that were saved on my desktop at work are in HPT version 2.23 Beta, If l bring the desktop home to use one of the original tunes in the car will my MPVI Pro still work with my laptop afterward, after using version 2.23 Beta with my desktop or will it become updated somehow to version 2.23 Beta only and no longer compatible with my laptop and version 2.22 ?
Also can l use a longer USB extension cable (say 5 or 10 metres) or would that cause problems.
