iStick Pico weird coil behaviour

[Kuhan_Vincek]

Hello all!

I've had my iStick pico for some 3 years now and I am very pleased with the device (together with Melo 3 mini tank).

Just ordered Aspire Cleito tank for better flavour though, but i digres.

Now to the point of this topic.

I'm using SS 316 mesh coils with 0.22 ohm resistance in TC most of the time. The wattage in TC is set to 60 W (to preserve battery) and temp is at 250 C. I get plenty of vape and decent flavour.

However, recently I tried going back to Wattage mode (just for fun) and I noticed something weird. I am getting no vapour even at the top 75 W.

If i take an unusually long drag, I can feel just cold air beeing drawn in my lungs for the first few seconds and only in the last few moments I get the rich thick vapour - like I normally get from the get go in TC mode.

From what I can remember from before I was using TC mode, vapour was plenty rich from the get go also in Wattage mode.

Can anyone help me identify the reason for this (strange) behaviour?

Hello @Kuhan_Vincek, no real idea at all why it's behaving like that.

But maybe NFE tools/firmware may help sort things out and add more functionality for you.

Here's the link to at least have a look at.

To answer my own question...

After doing some research, I've found out that some coils with larger mass need the preheat function in VW mode to function better.

After setting the preheat time to 1s and preheat W to 75W, my coild is producing normal vape also in VW mode.

All is well

Glad to hear that you got it sorted, but definitely look into NFE tools and firmware.

As the firmware adds more functionality and the PC software is a little like Evolv Escribe, which allows you to monitor and tweak/alter things to your preference.

I did look into it - used it to clear the puffs and seconds counter.

But other than that, I am pretty pleased with the stock device/software. I consider myself not a heavy user - not into rebuilding coils, making my own e-juices from stratch....

For now I prefer that everything related to vaping be easy and simply work as intended.

No worries, it's there if you need it though.
