Though I've not seen much activity from the ProVape people these days, I'm hoping one might see this message and offer some information.
I really like Coil Control but due to the lack of info about it, it is probably the most frustrating factor in my vape life.
The first time I used it, it was glorious. I spread the word where applicable just because it was so good. But now, it's definitely hit or miss whether it works at all - and for reasons I don't understand so troubleshooting is useless.
It almost never works with a new 1.8 or 1.6 coil, even when the vape was brilliant with the coil I removed. It displays "output error" at any group and any level so I'm reduced to using just the normal power adjustment. After a tank or two (or when I think of it) I can change to CC and it works great. THAT'S frustrating.
Leading to the annoyance is that I have no idea of how the groups scale. I don't know if A is less power/weaker than B or vice versa. Perhaps it uses completely different parameters and power isn't an issue. I don't know what raising the level from 1 to 2 does. More power? More duration? Both? Neither?
Like I said, frustrating. It's a great thing when it works, but when it doesn't the user is pretty much reduced to chicken bones and Voodoo to get things straightened out.
Maybe this is a question for customer service but weeks of back and forth emails to get the required info is annoying also. And though every one has proven exceptional at making a customer happy I don't get the impression that the CSRs are especially experienced in the deeper technical aspects/
30g kanthal is a pain as it is so thin. 28 is a good versatile wire, I mainly use 26 or 27
