My MVP will fire as low as one ohm. It seems like there is some variance, some MVPs only fire down to 1.3, some folks have claimed to have devices that will fire slightly sub-ohm.
I started building RDAs on an MVP so I know where you're coming from. You probably want to start trying to build good single coils. It'll be much easier to hit a resistance you need. Once you've mastered that try doubles. If you have an Android phone download the Vapers Toolbox app, it'll help you make coils. There are also plenty of online calculators for the same thing.
I'd try starting around 1.8 or two ohms. That should be pretty easy with single coils. If you use 28 gauge wire and a coil diameter of about a quarter inch you're looking at a 4/3 or 5/4 wrap.
