[QUOTE=We87][QUOTE=lordmage]i find ss works best with the preheat off. i use "Temperature (degF)","Electrical Resistivity" -58,0.915064 -0,0.95433 68,1 121,1.15 302,1.2 380,1.25 482,1.30 572,1.35 800,1.40 [/quote] I tried this with the 316L SS wire I have and it wouldnt catch temp control, just stood in power mode. Some profiles I have of DJaquith's worked (v3.25 and v7) Is there something additional I need to do in order to get that particular CSV to work? Or am I just doing something wrong? The coil was used in a Taifun GT2 IIRC it is 5 wraps around a 2.5mm which ohmed out on my reader at about 0.9 ohms for what its worth. [/QUOTE] i found what i have to do is play around with the first column a bit to get better performance my coil is a stock premade in the tfv4 which ohms out at .27 cold resistance. "Temperature (degF)","Electrical Resistivity" -58,0.915064 -0,0.95433 68,1 121,1.15 302,1.2 390,1.25 490,1.30 590,1.35 800,1.40 that's what i am currently running i also did the case analyser which could also play a factor. if one off Dj works for you then i would stick with it find your sweet spot and vape on if your not aware the first set of numbers corresponds to the temp the second beats me but it works for me. i usually run at 35-40 watts with no preheat 1,1,0. i also watch the curve as i vape it goes right up and climbs steady to me point then maintains which is when the curve bounces. i have yet to push temp past 400 and it works smooth for me. to much wattage and its all over the place.
