Basically the topic sums it up...why do you need to use a 1.3 ohm coil or higher with the VAMO
Can someone explain why there is a minimum ohm coils need to be at for vamos?

The limit is probably caused by the capabilities of the chip that actually drive the Vamo. Lower than that, and it can't decide if it's seeing a short or a coil so it shuts itself off for safety.
Lower resistance=higher current=higher heat which could=damage if it exceeds the ratings of the equipment.
If i'm not mistaken, most of the regulated mods are the same.
If you want to go lower, you'll need a mech mod.
Not trying to sound patronizing, but if you choose to do this, have you read the safety threads? Fer instance; http://www.e-cigarette-forum.com/fo...-discussion-safety-battery-info-warnings.html

It's simply because the vamo's board wasn't meant for super high current loads, so they placed an arbitrary cutoff of 1.3ohms. The vast, vast majority of vapers are using commercially available resistance levels that don't go below 1.5ohm. The 1.3ohm limit was probably to take into account the slight variance is resistance that you get with devices with a labeled resistance. A 1.5ohm carto might actually be 1.4 or 1.6, if the cutoff was right at 1.5 some might not work. That's my guess at least.
It's a bit of a bummer though, as the vamo has a 5 amp limit. That means it should be perfectly capable of firing slightly sub ohm coils at a down-regulated voltage. It would be cool if someone could figure out a way to reprogram the boards or something to accept coils down to .8 or .9 ohms. The vamo automatically down-regulates voltage if you are too high anyway.

It is for safety and so you do not inadvertently blow yourself up. A battery blowing up in your face or a meltdown would be hazardous to your health and appearance. I would also venture that when the devices were designed that there was not a lot of sub ohm vaping going on.
Baditude has a very well written and clear explanation regarding batteries and safety and types recommended for use on the different devices. I suggest you go read his blogs. There is also something here called battery university that will introduce you to the use and safety of the various batteries.

As most said, the cutoff is set at a given level to prevent damage to the electronics and overstressing of the batteries used. Vamo has no way of knowing what brand or quality level of batteries that will be used, so they set cutoff at a reasonable point that will protect us and the device from harm and damage.
Thanks for all the information! I'm not planning on doing sub-ohm any time soon. It just annoys me when I put the time into building a nice coil, and it ends up .1 ohms below the cutoff.
I'm sure I'll end up with a mech mod eventually, but for now I just need to keep practicing

Practice makes perfect. Or in my case, I just make mistakes less often, lol.
the power regulation chip is the determining factor in wattage capacities, plus the designers have to build in a safety factor to protect the chip from failure ( cant have 60% of your product failing and being returned, not good for profits) give it time, eventually someone will make a tiny chip that is capable of 40W capacity ( altho the mod will have some kind of heat sinking fins on it 
) and you will have to use the same batteries the the Mech guys/gals use.
