Problem of IPV D2 reading wrong resistant

[centella4u]

I just bought an IPV D2 out of all the hypes that had been going around just so I can use it with titanium coils since my X CUBE II refused to work even after I paid to upgrade it. Anyway, I was wondering that when you use temp mode, you're suppose to lock in your resistant by pressing the + and - key at the same time.mmI built my Tugboat with dual titanium coil coming in at 0.176 ohm (from my ohm reader) and when I locked it in after setting everything up, it showed exactly 0.176 ohm. The problem is the moment I starting vaping, the resistant went up to 0.21 ohm??? I have my IPV D2 set up at 333 degree f and at 33 joules, it vapes great. So, any idea why the resistant jump like that?

the D2 shows current ohm readings, but when you lock it, it remembers what the resistance was and all calculations for voltage are done with the locked in resistance. in other words, when locked, the D2 shows current resistance, not fired resistance

It's reading a hot coil. That is the highest it got on last use. It basically reads where it temp limited.

IIRC the D2 has a real time resistance display unlike my IPV3 Li. As exodus stated, as the temperature of the coil rises, so does the resistance. That's how the mod knows when the coil is up to temperature you set.

Edit I really need to type faster, everyone beat me to the punch

When setting your D2 (.176 in your case) that number shows up on the screen while holding up and down. when you release it goes away and shows 0.00 on the screen... tap the fire button once and it should then show something relatively close to what you had it set at... press and hold the fire button and you will see the ohms rise as the temperature rises... when you release the button it will always show the most recent ohm reading on the screen... believe me, your starting ohms (.176 in your case) are saved in the memory and that's the number the D2 bases it's temperature control off of.

Wow, great, thanks everyone. Now I can enjoy using my new IPV D2 with ease of mine.
BTW, this happened to me last night. I started to feel a dry hit then I remove the top cap to see that my cotton had gone dry. I pressed fire and .... whooosh, it went up in flame and stayed like that until I blew it out like birthday candles, lol.

When I carefully pulled out the cotton, just for curiosity sake, to see if the cotton was crisped or not .... this was the result:

I burnt clean the wire a couple of times then replaced the cotton and it was as good as new.

TC is very finicky when it comes to dual coils... they have to be EXACTLY the same in order for TC to work... for some reason TC can't read a hot spot very well on duals... singles on the other hand, TC works PERFECTLY! Glad I (we) could help man!

Does that mean I have to wrap 2-3 rounds on a single coil instead, just thinking is dreadful enough, lol. Thanks again @BenJammin

Why don't you just try the same coil, just use only one? turn up the heat and/or Joules if you like the hotter vape... with TC you should be able to get pretty much the same vape out of a .2ohm build as a .4 ohm build... In theory anyways lol... happy building and best of luck to ya!

Just wrap two spaced coils instead of contact coils and hot spots won't be an issue.

It will still have trouble detecting dry hits unless the coils are exact... even then it's not guaranteed to work properly...

 

[BenJammin]

All of my advice is based off of personal experience and after talking with other people about it as well... IMO single coils are the way to go with TC...

 

[centella4u]

Good enough I can bulild at all, so .... single coil it is from now on.

At the very least, try it out and see what ya think... be sure to try spaced as well as contact (if using Ti) to see which type of coil you enjoy more... it's all a process of elimination when it comes to TC... it's like re learning how to build...

Actually right jow I'm quite happy with this build, the taste is better and vape cloud is there. But ues, definitely, I love to try all you guys suggested. Vape on, vape strong, for the health of you and your love ones.

Might take quite a few wraps with a nickel parallel.

 

[BenJammin]

I haven't rolled a TC build for a couple weeks, so...

For duals, just roll parallel and unscrew them. Matched pair.

A question of my own... with Ni, what's the result of leaving them together and running a single parallel?
Contact? Hot spots? Resistance reading?

First of, as lefty mentioned you would need like 14 (maybe a couple more) wraps with 26g parallel to get above .05ohms... Secondly when nickel touches it creates hot spots due to the low resistance
