I have a tc40w eleaf and a Herackles plus tank and I ordered new coils but my supplier send me some 0.4 ohm 35-100w coils when I was using 0.2 ohm nicid coils because its all he had in stock . so that means  have to use vw mode instead of tc mode ? Am I right ? or should I just send them back and wait for the 0.2 nicid
