    Hello people, i am a fairly new vaper and user of this forum which i have been using as a guide and help since i started vaping. Now i am not a complete noob in vaping, do a fairly good reaserch and try to figure things myself before bothering anyone with already answered questions. I have tried to find as much info online and in vendors ( there are no local vendors here i have to travel at least 60km/40miles to find a semi-decent store) but i hit a dead end so i now need your help.

    First of all my mod is the Innokin Itaste Kroma a 75W mod that works in TC and my tank is a Veco plus tank with the EUC coils. Even with the original tank which was the slipstream tank i found vaping in TC far more enjoyable than wattage mode which i never got to like as much as TC. With the sliptream tank which used the straight ss360L 0.5 coils, TC was straightforward vaping at around 220-230C/430-450F but i had some issues with those coils and i decided to buy the Veco tank and try the ceramic ones.

    Now i have been trying to work with these 0.5 and 0.3 ceramic SS coils from vaporesso but TC is acting a bit strange. through trial and error i found that they have some break in time (about 4ml) and thats ok. next is my first problem which is the temperature. During break in i use it at 160C/320F then slowly ramp up but not by much. I can vape at 175 to 180C/350F max before things start to get wonky. if i put the temp at say 200C/390F the coil vapes at 165-170C/330F for a second with an okay-ish taste and then it jumps to my selected temp instantly and the taste goes really bad with a ceramic/burnt feel.
    I asked a couple of stores about these coils, one vendor told me that i can only use these coils in either TC or Wattage mode but one coil can only be used in one mode and i cannot switch between them even when coil is cooled down which i found weird, the second store told me that these coils are not useable in TC at all which i found weirder than the first advice.

    So my question is how can i use these coils to get the best experience? Is this behaviour normal?Am i doing anything wrong?

    Side info: I moslty use homemade 50/50 3-6 nic juices with light flavours like strawberry coconuts apples chocolates and vanilas(~10% flavor total), i have set the wattage in TC mode at 45-50W if i set it to the max 75W i get the ceramic/burnt taste as soon as i fire the mod no matter the temp i set it to.

    Any help or insight is much appreciated, i know it was a bit of a long read and sorry for that, but i think i had to describe all the factors in order to pass on all the variables (which when it comes to vaping there are a LOT)

    The problem you describe is often caused by setting the wattage too high in tc mode. A good start is to vape the coil in vw mode and get the wattage about where you are comfortable. Then let it cool down change to tc mode and set the wattage the same or just below where you had the best vape in vw mode. Also don't forget to lock you resistance in tc mode while everything is cold. If that does not produce good results you probably have to go to your tcr settings to adjust for your wire.

    I have the same ss EUC coils running in my supertank mini. I use them in wattage model at 30.5W and tried temp control 400F 19.5W but very muted flavour.

    Maybe I should ramp up wattage to 30W levels but would that really help given temp is controlled at 400F?

    Or maybe I should up the temperature? Will experiment and revert here!

    I only made a brief attempt at tc with my euc coils. It didn't work at all for me. I tried some very respected mods and got totally inconsistent results. TC requires excellent conductivity to work properly. I own 2 different Vaporesso tanks and neither will do tc. I still like the euc coils a lot but only use them in vw mode.

    Success!!!! TC on a DNA75 using the 0.5 ohm coil. Sweet spot hit at 28.5W and 440F. resistance locked at 0.65 ohms (thats what the dna reads), using 80% vg juice. Consistent sharp clean flavour, nice saturated vape.

    Thanks, I was worried about cranking up the temp and wattage!
