I have quickly scanned through this so if i missed this sorry, but once you set up your profile, you lock the ohm's in, best to use an external ohm meter with a room temp coil, also the you are talking F or C ? I use steam engine for my TI build and works with no problem. Now coltcannon you said you made a new coil the same way so it should have been the same, maybe ohms might have changed a small bit but you should have been able to use that same profile with no problem.
