I have the kanger ssocc ni200 coils and am using the in the Koopor plus. I have the settings on temp mode, coil ss, sc, set at the default .00105. The coils are .15 ohm. The problem I am having is that it will not fire when it reads the ohms at .15 or close to it. However, it will fire when it reads the ohms above .3. Should I have the settings to ni or ss? The coils come in a black box with SSOCC in blue lettering and ni200 in the bottom corner of the box.
