I had a feeling that was the case, beating the FDA dadline, but unfortunately for me, that still leaves me out in the cold since I have no way of tweeking the pre-set values. The only setting that sort of works with a 0.59 ohm SS coil is the "I" setting but that one is like sucking on a volcano even at a setting of 1. I'm going back to my 0.8 ohm kanthal coil and hope the next upgrade will be better.CC does work well but how it works only provape knows for sure. I personally think they had to rush it to beat the FDA deadline and didn't test it with much more than what's on the chart. I've done some testing and their chart is a good base to start from for premade coils.
