Cummins Inline vs Nexiq, best CARB smog software

[montrose818]

Hello. Two questions.

1. Is Cummins Inline same device basically as Nexiq?

2. Just passed the test for the CARB heavy duty inspection and maintenance tester, looking for the best softeare to use, options are

Silver Snap-Tool
DAWN OBD Inspector
Truck Check Up
DPA Inspect

Not sure if anyone has any experience with this, but since its not required in CA, no rea way to avoid it

Another question would be, will a demanded engine be an issue? I have never ran the software.
