Sounds like Stark may not even know exactly what will and will not be included. A couple clarifications, a SIM card is only needed in their included phone/gauge if you want it to connect to cellular towers. Otherwise it's via wifi which I'm fine with. And you can have the Varg app on any phone and make adjustments there when you are not around the bike and then load those back to the Varg phone.
From my perspective, I don't need to save 100 configured modes. I can see 10 or so, but even 5 would be good for me since one can only have 5 loaded and available on the bike at any given time. I would want/expect the adjustability to be available to non-paying members (power curve, engine braking curve, Virtual Flywheel Weight Acceleration, Virtual Flywheel Weight Deceleration, and Traction control). While I'd like access to the nav, I really don't need it as I have maps on my phone and don't need to reference them much. Same with the "race" type features such as lap times, speed, G-force, air time, etc. But we'll each have our preferences on what data we value depending on how we plan to use the Varg.
But I think all of the adjustability is core to the bike and so that should be included for free without subscription.
