I was wondering how dual coil attys are actually built and what OHMS I'm actually running at. Are they wired in series or parallel? So if i'm running what is stated to be a dual coil 1.8 Ohm what am i actually running? Are the Ohms already calculated and I'm nuking this.....
Question about dual coils...

A 1.8ohm dual coil will read at 1.8ohms, it's already calculated for you 
If you want to know how they're built, though, it's two coils in parallel, in the case of your example it's two 3.6ohm coils sharing common positive/negative connections to the battery, yielding an effective resistance of 1.8ohms as well as doubling the surface area of the coil in contact with the wick/polyfill/juice.

Since there is already a variable example available here, a 1.8 Ohm dual coil will read 1.8 as the resistance. Since they're typically parallel connections, you can essentially double the resistance with a dual coil to find the individual coil resistance. Parallel Resistance= 1/(1/3.6+1/3.6)...1/(2/3.6)...1/(1/1.8)...Resistance=1.8.
The overall resistance is 1.8, but you can use a higher Power/Watt or Energy/Volt output due to the larger amount of surface area there is to heat up. My mod allows me to choose between a setting that allows full power output immediately or gradual build up to the full power output. Since I always use it on the immediate setting, I typically don't raise it that much higher than if it was a single coil. If I used a gradual build up, I would put it up a little higher. Just use the typical method to decide what output you should be using. Gradually increase the power until you get a moderately burnt taste, and decrease it accordingly. You will more than likely be in the red area of the Power charts able to be found in this forum.

Mine seems to be vaping allright on an eGo 1300mAh that runs at about 4.2 at full battery. I tried one juice in it that was simply horrible through dual coils that was fine at 2.4 single. Didn't taste burnt though, just didn't produce vape at all or very little compared to previous
