Mactavish,
Don't make to big a deal out of all the settings you'll drive yourself nuts.
If I was you I would leave the pre-heat temperature and the pre-heat wattage alone. The Evolv Factory settings of "5' and 200 Watts are just fine and that is where mine have been from day one
The item that you call pre-heat Temperature is called Pre-heat Punch and that is the only thing that will change the temperature of the pre-heat. The 200 watts is used as needed to take the coil temperature to within 100 degrees F of you TP setpoint or the time you have set (default 1 second) whichever comes first.
I also wouldn't mess with the time setting and leave it at the default 1 second.
Unless you are out Duck Hunting in northern New York you will never ever need or use all the defaults the Pre-Heat can deliver. Also a lot of folks turn down the pre-heat. They read the 200 watts and freak out but as I said the Evolv chip is smart and doesn't ever just dump the 200 watts to the coil it only applies what it thinks is necessary and you would be hard put to find anyone claim they have seen it fire much about 75 watts during preheat. Now this is the time that a guy that works as a Butcher in a freezing meat locker shows up and claims he sees his hit a 100 watts all the time.
Anyway until your usage proves me wrong just come up with a few simple curves for different metals and let it go with that. Oh one thing I would keep an eye on is the battery setting i.e. watt hours, voltage and mAh setting. When you get your LavaBox check and write down what you see. The reason I suggest this is several of the Mod Vendors did not preset these values for the battery they used. My VTbox200 came with the Evolv default of 900 mAh and they had put an 1800 mAh battery in it.
Also don't start worrying about this too much either. If it has the wrong values (I think LovaBox is a 1300 mAh Bat) it will not hurt a thing it will just change the way the battery bar shows remaining battery poop.On the subject of Batteries there is one value I would make sure you change (I will catch some flack on this but trust me). The Evolv default for the soft battery cutoff is 3.09 in my honest opinion is too low and I have mine set to 3.2 (which is a value condoned by Brandon) just as if it was a standard 18650 battery. If you leave this low you can reduce the life of the battery (if your make and model battery doesn't like it). If you take my suggestion and set it to 3.2 volts the worst think that will happen is the battery will will power your device for a little shorter time than it possible could (we are not talking much time here) but your battery will love you for it and live to a ripe old age.
