@ljc5150 An analogy for TC would be cruise control on a car, with the throttle being the wattage and your speed being the specified temperature. So in essence the amount of wattage you use only changes how quickly you achieve your desired temperature (assuming you use
enough to reach that temperature).
Temperature limiting might be a better description as when the coil reaches the requested temperature, the mod will back off the wattage to maintain that temp.
So set a reasonable wattage that you might use for that coil/s, set the temp to something like 350f and see how you go. You might find that the temperature limiting is coming down too hard, so increase the temperature incrementally until you find a vapor production and heat level that suits.
