Welcome to VT yiton!
My guess is that it's the eleaf 60W TC with the melo 2 kit. If you left in the stock coil, it's a 0.3 ohm coil I would start in wattage mode around 25 watts bumping it up a little at a time until it tastes good to start then go a little past until it doesn't, then back it down a bit and you'll have found it's sweet tasting spot. The other coil in the kit is for temp control, that's a whole different process.
Here's a good youtube review that will explain the mod controls better :
