It would be very helpful for troubleshooting purposes to have temperature accuracy specs from YiHi for at least their recommended oHm build range. Specifics as to what they mean by "some unexpected behaviors" for 3+ oHm builds would also be useful to know. Since you have staff on the ground it would be a welcome contribution to the community if you could have them get at least that bit of information.
YiHi's owner/lead engineer does not speak any English. All of YiHi's large manufacturing customers who would need technical information are Chinese. The people doing YiHi's communication in English are sales people not techs.
Here's what I will do for you all. Write a list of questions and I will have one of my Hong Kong guys (they talk Chinese) to get some answers. But please keep it constructive and let's be very respecful. No comparisons with DMA stuff as that will be taken as an insult. Just keep it simple and to the point and I will try. I got a lot on right now but sure, why not.
I will say one thing to everyone. This tech is so important I think we should all cut-each other some slack. Even when you know you are in the right. If this were another tech then fine. Argue it out. But vaping really needs some sold comunities to show everyone what all this is really about (stinkies!!!). We really need solidarity and I see that a lot here. So I will try and help where I can. Not that it will count for much. But together who knows.
Good stuff and you clever boys have a group hug
