OXVA Xlim Pro 2 DNA Problems - "Fill Pod" and Stuttering Vape

[Simon Martin-Lemmon]

Hi,

 

After an exciting wait, I eventually bought a few Oxva Xlim DNA pod kits here in the UK a couple of weeks ago alongside some 0.8 ohm stainless steel pods.

 

Generally, I am very happy with them, but I have a couple of significant issues.

 

1. When taking a draw, I am getting stuttering intermittently, like it is not getting a clear air flow
2. At other times and more and more frequently, I am also getting a "Fill Pod"  message and red light frequently, even though the pod is full, to the point now, where it is becoming unusable.

 

In both cases I have tried.

 

1. Using different pods
2. Used different bodies / mods
3. Tucked or blew through the pod when it is removed from the body
4. Ensured battery is fully charged.
5. Ensured contacts are clean and nothing on the contacts in the body.
6. Tried restarting.

 

All of the above does not improve anything.

 

I have been reading through the thread linked below, and managed to update escribe as detailed, and tried changing some of the settings, but all to no avail. I suspect I may not be using the right values as the thread below is aimed at 1.6/1.2 ohm atomisers and not 0.8ohm.

 

It is really disappointing having been a dedicated DNA advocate and user over the years when using subohm gear, and my initial excitement for the OXVA DNA Pod has wained massively.

 

I did send OXVA ana email and they got back to me saying that you were working on firmware updates.

 

Please could you advise.

 

Many thanks

 

Simon

That other user had some different issues. Have you updated the firmware on your mod, from the file on this site, and what is it.

[Simon Martin-Lemmon]

Thanks for the prompt reply @Wayneo

This is what I have at the moment

Closing the airflow a little more, or increasing the pressure while taking a hit might help fix the stuttering issue.

As for the 'fill pod' issues, I have no advice and I hope you did not change any parameters in escribe. If you're not sure you could always reload a copy of the original.

Hi @Wayneo

Thank you for the reply.

I have tried everything that you have suggested, all to no avail. I would like to make it clear that I am not new to vaping, and have been vaping now for around 10 years as well as being a promoter and advocate of vaping here in the UK, and also being a very committed user and advocate of DNA based mods. I have been using the OXVA XLIM pod kits in their different versions for around the last 12-18 months without ever having seen the stuttering issue on non-DNA versions. It is only since I started using the Pro 2 DNA with the 0.8ohm pods, that this problem has arisen. As mentioned, I actually purchased six of these units and 10 packs of pods and have tried all of them, and they all demonstrate the same issue, so it is nothing to do with an individually faulty mod or pod.

Regarding the "Fill Pod" issue, i am very disappointed that your response is just that "you cannot offer any advice". This is absolutely not the level of service I would expect nor have experienced over the years from Evolv. There is definitely an issue, and again, this issue is across all of my mods, and after trying different pods. I did highlight that I had been reading another post, and your response was that it was a completely different issue. I don't think it is. The post I was reading was the one below, and feels very similar to my issue. The recommendation in this post was to actually make changes to the settings, where as your response to me was quite a patronising answer saying that you hoped I hadn't changed any settings.

I apologies for what might be a perceived abrasiveness, but your response feels wholly unhelpful and lacking any focus on support around my issue.

I will go back to OXVA linking this thread to get their thoughts.

Hello,

Would you mind posting a screenshot of Device Monitor when taking a puff, or posting a recording CSV of the puff? I'd be interested to see what Power is doing, and what the Live Ohms are. Make sure to check those. You can click on the trace as it scrolls to get the values at a particular moment in time.

Your screenshot also shows Cold Ohms as 0, which indicates it hasn't fired yet I assume. What do you measure for Cold Ohms for the coil?

I'm curious to see what limit you are running into.

Thanks!

James

Ws confused by the discrepency in resistances now I'm just disappointed in the performance of the 0.6 ohm (0.35) coil. And tbh designing an element/coil with similar thermal properties and  labelling it  'comparative ohms' doesn't work for me. Vapes like the resistance is too low.

Can't blame the board for the coil design.

Power delivery has been fine and vape has been smooth in mid power range ( for a low resistance/ fast reacting coil in a tiny chimney) anywhere above that and boost cooks the juice and TC throttles back all too soon.

Not ideal running over 0.3ohms cold particularly other mods (I'm going back 10+ years lol) which struggled to function with SS at higher warm resistances but in the past I have used 0.5ohm SS with single coil RTAs and come closer to kanthal / nichrome performance.

@James Bellinger Thank you very much for the reply and apologies for my delayed reply. I have been up to my neck in DIY all weekend, under duress from my wife 🙂 

Anyway, I will get on that today, thank you.

Having done a bit more checking over the weekend, I am starting to agree with @franticseven in that it might be coil related rather than board. I check the resistance under Escribe late on Friday and for the current 8 ohm coil I am using, the resistance is showing as 0.5 ohms. It is still relatively new and not showing signs of degradation in terms of performance and flavour (when I can get it to fire) but just seems to have given up the ghost early.

I maybe wrong, but once I have finished work today, I will report back later as requested.

Thank you.

Hi @James Bellinger

Please find attached log files from eScribe Device Monitor.

I have two mods, and two pods. One pod is 1 week old, and is the one that is struggling. Please note, there is no degradation in flavour on this pod, and other than the fill pod message, it is still going strong. On the other pod, this one is one day old and seems to be fine, although I do get the odd fill pod message.

There also two photos. The one on the brown mod is the 1 day old coil and on the white mod is the 1 week old coil

All files are named accordingly.

I hope this helps.

Many thanks in advance.

Would you mind checking Cold Ohms and Live Ohms as well for the recording? It only has Power right now, from which I can't make a huge number of conclusions. (It only records the columns you have checked in Device Monitor, plus time.)

Is your Power Setpoint 18 in all of these? (It's not recorded.) 

I do notice in the "Worst Mod" cases, the power is clearly declining, which suggests it is hitting a limit of some kind, but hard to tell only from that.

What will be interesting to see is what the percentage difference is from Cold Ohms to Live Ohms in the "Good" case. That'd tell you how close you are to the "edge" (24% for the Stainless coils at current presets).

Thanks!

Hola, yo he encontrado una solución sencilla, es bajar la potencia a aproximadamente 6w, luego seleccionas el REPLAY y subes la potencia, en este caso funciona sin salir en mensaje de rellene el pod.

Espero sirva de ayuda, aunque sea una solución de andar por casa, pero he probado otros ajustes y sin buenos resultados.

Lowering the power seems to help with these issues for me. Weird we can't adjust by temp though imo
