SS430 has almost twice the TCR of SS316L and worked better with TC. SS316L is more like temperature limiting under TC than an actual temperature control.
The latest DNA 200 firmware has smoothed out the SS316L control now to where it is as flat as SS430, SS316L used to have a really jagged sawtooth graph.
I would suggest you might want to install a virtual box emulator on your Mac, pick up cheap windows tablet or old laptop to enjoy all the options you can tweak with your DNA device in eScribe.
Depending on your version of OS/X some of this info might work out of the box. A separate partition or purchasing windows is not required.
