Apologies if this has already been covered, I am sure it has, but likely a long time ago (I've been out of the game for 2 years) and despite efforts to find the answers I was not able.
I am considering trading in my MPVI-1 for the MPVI-3.
I have about 260 credits on my old MPVI-1, mostly for vehicles I no longer tune, but I still have a couple I use. My understanding is that access to advanced features on the MPVI-3 requires a tuning class. While this class may be basic, I'm short on time and prefer not to take a class just to continue modifying vehicles I already own and have invested in.
-Are there exceptions for needing to take a class for vehicles you already had complete advanced access to prior to upgrading?
-What abilities will I lose concerning the new emissions compliance if I upgrade?
My vehicles are a 2016 Cadillac CTS-V, a 2018 Corvette, and a 2017 Ford F-150.
Thanks in advance!
