I really think it boils down to how much do you like to tinker with things? Fuel management is always a balance between power and fuel economy. Maps give you the ability to precisely target areas where you want to improve performance and where you want to improve mileage. Without maps you get whatever power/mileage philosophy was engineered into the unit...and that may be sufficient for you.
Here's the way I look at it. Not everyone's riding situation is the same. Some people ride in flat areas, some people ride in hilly or mountainous areas. Some people ride predominantly on surface streets at 50 mph or less, some almost always are riding on freeways. So it makes sense that you might want to tailor your performance to your situation. The thing I like about the Cobra design from what I understand is it's adaptive as opposed to other non-map systems in which you have a few settings you can change. However, without maps you can never actually see the adjustments or trims your bike is making. Sometimes that can be useful if you are of a "tinkering" mindset like me.
