I have the Splinter Z and a Lost Vape Paranormal DNA250C box mod. I used them for about 5 months and have never used anything but wattage mode. I realize having a such a sophisticated mod just to run in wattage mode is probably overkill, but I did not realize at the time I bought how frigging complicated or confusing the TC mode can be, and had no luck with downloading profiles as suggested here. Besides which, I am totally satisfied with the results I get from the Z and Paranormal combination. As for combustion, I believe that is a result of riding the fire button too long, drawing too slow, or both. I can combustion at 38 watts, so unless you are using TC mode, I believe you still have to do some regulating with fire button and draw speed, though not nearly as much as with a Milaana. In fact when I received my Milaana2 back from a repair, I was charring my loads after the second draw because of the unregulated nature of the beast. As for the Splinter Z, the coil resistance is .43 and the average wattage range is 37-39; when using a rimmed top hat screen the wattage is 38-40. I have never gone higher than 40 watts since it requires more attention to keep from charring the load. So good luck to all and a big shout out to Ryan; in my humble opinion the Splinter Z is about as good as a vaporizer can get.
