Understanding how my evic vtc works in TC mode with Ti

[cyberlollo]

you should start by setting it to Temp-Ti mode, then set your temperature, then set your power around 50w. The thing is you seem not to understand that you are vaping to a temperature not a wattage. Make sure you have the thing set for Titanium first, then set the cold coil resistance, then pick a starting temp, then pick a starting wattage. If the Mod say's it reaching Temp Protect and throttling right back then it's doing it's job. If the vape is still to cool you need to increase the Temperature setting, If It's too cool and it never shows Temp Protect then and only then do you need to increase the wattage.

I tried as Tubbyengineer said, 250C 25W 0,37ohms it reaches the temperature but far from what I like.. should I increase more the temp? what's the max temp I can safely vape?
(I also tried to take a few primer puffs to get the wick and coils well soaked and nothing change..)

That said you could have a faulty unit, I have a faulty evic but I have convinced it to work. Try the following, exactly in order:
1) Unlock the mod (if resistance is locked) and take the tank off.
2) Let it cool down completely or use a different tank
3) Switch to voltage mode, then attach the tank
4) Whilst still in this 'mode switch' setting, change to Ti mode
5) Lock the resistance now whilst still in adjustment mode
6) Press the fire button

You should have the resistance locked in at the right setting and get a bit of consistency.

When working properly you should press the fire button, the mod will heat the coil to your chosen temp setting then 'temp protection' should show on the screen, this tells you the unit is working correctly.

Just tried, no improvements..but the resistance now is 0,01 higher, 0,38 vs 0,37..not as much to make a difference anyway..

Did it start to flash the Temp protect message? If it did - increase the temp 10 degrees and try again, if it didn't increase the watts. The temp protect message means it's reached the preset temperature, if it isn't doing that more power is required...

250C is a pretty high setting - if your tank has high airflow, you may be better off setting the wattage higher. I use 25W for fairly restricted airflow (eg. middle hole on the subtank mini) but for more airy tanks I set to 35-50W. If it's still not giving decent warm vapour at that setting, then my bet is that it's a wicking issue - probably too much wick. If the device doesn't wick efficiently, it causes the coil to heat up too fast and the power to cut out almost immediately, resulting in a weak vape. Increasing the temperature setting (or calibrating the coil when hot) will stop the power cut out, but you are no longer regulating temperature and will likely get charring and even dry hits.

Maybe posting some pics of the wicks would help?

Yes it shows the protect message, even at 255..where I still not get a good vape..

Give me 10 minutes and I'll post some picture when I'm wicking

Here some picture of how I rebuilt..
Cotton Muji, removed the external parts of the pad, for make it less dense, and tried to open the fibers stretching the cotton by hand..
the first two pictures are about how it was build, and after how I rewicked now..

It looks OK, might still be a bit too much, really you need to get it so that it's at the very edge of gurgling, the other thing to look at is that coil is awfully close to the sides, try tweaking it so the wraps are a little closer together giving more space at the ends of the coil so it's not touching the chimney or posts...

I think the only way is reducing the diameter of the coil from 3mm to 2,5mm what you think?

Is here any way to say thank to a post from a user? is it clicking like at the right corner of the post?

You could reduce the number of wraps to 5 (I count 7 in the pic) - 0.25 Ohm is plenty for a Ti coil and a shorter coil may reduce any choking of the wick.

 

[Tubbyengineer]

No need to reduce the coil size just press the wraps a little closer together, you only need half a mill to a mill of clearance from the posts and wall and about half a mill between wraps - you should be able to tweak that coil no problem...
