Did you find time to look for the strategy on your package?
I haven't had time to go back to the vehicle yet, but does this look like what you found?
"Vehicle Information
Vehicle information shows the make, model, year, VIN, vehicle
interface type, OBD-II type, CAL, and CVN information. If any
enhanced interface options are active, then you may see more module
specific information in the Vehicle Module Information list.
The ECM Information is where you can determine the ECM ID
the ScanTool is communicating with and the CAL and CVN IDs for
it. Only late model vehicles will report CAL and CVN IDs.
The ECM ID will help you determine which control module
your vehicle uses in some cases. For example, Chrysler will use different
ECM IDs for different ECMs. The ScanTool will display this
information if available.
The CAL ID is the Calibration ID of the ECM. Simply put, it’s
the binary fingerprint of the ECM’s current program. Dealers can
use this information to determine what revision of the ECM you are
using for possible reflashing recalls.
The CVN ID is the Calibration Verification ID of the ECM.
This is used to determine who installed the CAL program.
Emissions testing centers and dealers will use this information to determine
if the vehicle’s program was reflashed privately or by a
factory tool."
Interesting that the Smog Guy can see if you have a factory tune or not! Could they fail your smog test for this?

they just do an opacity test when you hit redline 3 times in a row
I wish they would just use the port to see if it was compliant like they do with gassers redline is a pucker maker
