You shouldn't be running any TFV8 coil in TC mode. Unless something has changed, as far as I know they are all made out of Kanthal and they are power mode only coils. If I remember correctly that particular coil is rated from 50 to 240 watts with a best range of 100 to 150 watts but it is a power mode only coil.Hi. So I bought a Cool fire Ultra and a Cloud Beast TFV8. I accidentally switched it to the temperature control setting and messed up what the temperature was. Can someone tell me what temperature I should set it to for a V8-T6 coil?
