OK, I'm a little confused on Temp Control. On my sigelei, I am using a Ni coil in my Herakles and get a great vape at 400° and 35w. I also have an eVic VT with an eGo 1 topper. I have a Ti coil in the eGo 1 and in order to get a halfway decent vape I have to have it set to 500°. Is this typical to have to have the temp set 100° higher for Ti to give a good vape? But again if I have the eGo 1 set to Ni with a Ti coil I get a good vape at 400°. I'm confused.
As long as you have the right coil and mode set (TI or NI) on your EVIC or NI on your Sig whatever setting you end up with to be happy is normal. Sure you can have all kinds of swings like that.
Specifically though if you use and NI coil in Ti mode or vice versa things are more thrown off, but again you can usually manually adjust to satisfaction. Personally, I'd stick with the proper matched settings and crank it up until you are happy.
