AEM EMS V1 vs V2

So maybe someone can lay this out for me. What's the benefit of V2?

Nothing caught my eye in a side by side comparison, so maybe someone else saw something I didn't.

V2 has flex fuel capabilities

So if we just plan on sticking with pump gas then there's not really a point in going V2?
