I wasn't saying some of the software couldn't be reused, I was saying it isn't as simple as just copying it over. With more power applied in TC the algorithm that controls this would have to be adjusted.
I knew it was designed by Suprimo, it is not hidden.
I don't get the Hohmtech reference?
Okay that makes sense. It seems like you were dismissing that anything Suprimo has done in the past could have affected the development of the device.
As for Hohmtech. Their TC is done by pulsing the wires to get internal temp readings instead of basing it off of resistance changes (even very minor ones like SS). If Hohmtech was producing it for Suprimo none of their TC work would have ever had chance to make it over to 213. But since everyone else is using the same science to work with the coils it's all pretty much data collection and data input at that point.
Considering the philosophy change from Sig's previous work (though I only have the 150TC to base it off), the TC in this is a complete 180, forget TFR, just including TCR is huge for them. Heck including anything but nickel support was rare (just looked and only found two devices supporting Ti), now they have the 3 major SS types. Also again based off my 150TC, has Sig even used Watts in Temp control before. Mine only uses Joules and I know that's the case for a lot of devices.
Hell reading most of that. I am convinced that RpadTV was right. Besides being a what seems like a great all in one device. So much of even the software is such a big departure for Sig that I would guess that even if Suprimo didn't port over their previous software implementations, that they did design with Sig most of the settings and software.
