I already know how to wrap regular dual 24 gauge coils but I would love to know how much resistance and wraps would work for a parallel coil. I use steam engine most of the time already. I have only had 1 experience with a parallel coil and that was a single coil, blindly wraped it cause I got a sigelei 100 watt.
How do parallel coils work?

A parallel coil in theory increases your coil surface area, theoretically resulting in more vapor production. It also halves the overall resistance (ohms). It is essentially a dual coil masking as a single coil.
For example, two single coils of 1.2 ohms on a RDA gives an overall resistance of 0.6 ohms. Wrap those two 1.2 ohm wires together (parallel) and you should still get 0.6 ohms.
Two 0.6 ohm parallel coils should give an overall resistance of 0.3 ohms; essentially what four 1.2 ohm single coils would be (a quad coil build). Get my drift?
Just remember that varying diameters yield coils with widely varying resistance. 30 gauge will let you wind more turns than 28 gauge for a given length. Also note that with more vapor production, there will be more e-liquid consumption. Along with this, you'll be able to drop your nic concentration.
You probably already know, but always use an ohm reader or digital multimeter to measure your overall atomizer resistance prior to actually firing the coil. Insure that that coil will not draw more amps than the battery has to give. When using an Ohm's law calculator, always use 4.2 volts as the voltage (a fully charged battery).

Basically if using Steam Engine, a parallel wrapped single coil would be entered in as dual coil, and a parallel wrapped dual coil set up would be entered in as quad coil to output the correct resistance. Turns and wire gauge are dependent on what overall you are going for.
I'm just getting in to coil building, I can't wait to try a bunch of different styles of coils! After the info on here, I'm adding a parallel coil to my bucket list.
