im stuck here at work and my vivi nova is acting up! during lunch i went home and put a brand new head and juice in the tank... so far its been super harsh! bad to where i cough everytime... i dont know what to do?

I'm assuming you know your stuff about voltage, resistance, and wattage.

The reason is most probably the fact that the wick has coils that are touching together. This is referred to as "hotspots" and it's nigh unvapeable. Expose the wick and adjust the coils. Keep them close, but not so close that they touch. Problem solved. Next?

I rarely go over 3.8v with my vivi novas. The provari uses a PUlse width modulation. This means it varies the length of a 6v pulse to effectively produce the equivalent of the voltage desired. You may find yourself finding a lower voltage to be more to your liking. Start low and work your way up till you get the desired results. You may have burned your wick in which case it will never lose the burnt taste.

so whats the deal with that lil paper thingy on the coil? i have never noticed one before? i took it out with tweezers and its starting to do better???

It's there to insulate the coil and the exposed wires (mostly the + side) from the barrel of the head. I've taken some of them out as they do char/burn/singe easily, and I don't plan on using them when I rebuild, but I haven't noticed a huge difference with or without lately. Maybe I've been lucky……I remember an improvement when I took one out of a head.

I'm not sure exactly how their circuitry works, but the Provari puts out a pretty much flat signal. It uses PWM as part of the circuitry, but plugging one onto a scope looks nothing like the other PWM mods out there. So it's not just firing at 6V and varying the duty cycle.

And based on my experience, 4.2-4.4V on a 2.8 ohm head is not that high. I run my 1.8 ohm heads higher than that and don't get burning flavor.
