Right, I think you need to clear the decks on this one, Plug in your mod, make a note of the battery settings and then select NEW file to reset everything in the profiles to default and then, re-enter your battery settings (or enter them using the Watt Hour calculator) then upload to your device.
Now create a profile for the Crown using 50w pre heat, No Ohms lock, 40w power, 390f. These are settings that have worked for me on similar tanks, if the dont work for you then you need to investigate the tanks or connections...
