Cummins Inline vs Nexiq, best CARB smog software

[Btech]

I don't have to worry about carb checks and all that where I am so I can't speak on the software you listed, but since you are asking about that you will probably want to get a nexiq USBlink 3 adapter. It supports all the newest protocols that new trucks are starting to use.
The current Cummins inline adapter, inline 7 is a nexiq USBlink 2 that is made by nexiq for Cummins. Probably in the next 5 years it will not be supported any longer.
Also note some software companies have their own proprietary adapters you must use with their software, so keep that in mind as well. (This is a practice I despise)
