Keep in mind, I've only had a little while with the imp, so this is subject to change. But i have found some settings that are producing beautiful vapor, and the temp control is working very well. 360 barely pushing clouds but insane flavor, 430 very dark avb. The temp feels close to other vapes i have used at the same temps. I am using a vtc dual using the tubo firmware, with the longer bead filled cooling stem.
Coil is locked at .227 ohms (this may vary per device a bit) power set to 30 watts. TCR set it tubo mode is a bit odd, i just set all three to the same value to be safe.TCR (tubo set) 180. All three. Temp 380 to 430. That should be enough to get some of ya started with temp control.
Eco mode works too, as well as cruise. I will keep at my testing, and hopefully make a video tomorrow of a sesh and walk thru my settings.
