I've tried two 316L wires, and I've tried three stainless curves and none of it is accurate. I'm guessing we need to make our own. I have a vested interest in creating my own temp curve - but I don't know how to do it or if it is reasonable for an average user to do so . Does anyone have a link to a how to on creating the profiles? I bought a pound of 316L on ebay, and the wire is very good, I just can't work with it in temp control - a pound is roughly equivalent to 1500 ft, for about $18 shipped... as you can see with that quantity It would be great to accurately profile it. Some users have stated that the change is too miniscule in resistance to get accurate readings from stainless - at least to the level of nickel. I haven't found Titanium particularly good either, but better than stainless
