sur_myevic would be my choice

Either way you'll get better temp control and more to tinker with and fine tune your vaping than the stock firmware
Arctic fox will let you add a TFR material profile (better than TCR)
Sur_myevic will give you the option of autofire (cruise)

Didn't try TFR yet. Does anyone have good settings for the IMP ? AF a does have a 15 sec draw time setting that is enough but no cruise mode that is really nice on FJ. I don't use cruise too much though because I am afraid it can roast the cover too much.

Set the TCR to 185
Read the resistance and subtract .01 from that
Set the mod to about 190 degrees C
Test (increase the temp to get an idea of how far off you are)
Increase the resistance in .001 or .002 increments til you're happy

Aaaand
Enable PID mode in vaping > algo
Switch off the screensaver in screen > saver
Set the contrast to about 10% in screen > contrast
Disable the modes you don't use in vaping > modes
Set prot to 25 in vaping
Enable Autofi and set the ATime to infinity in vaping
Set the clicks you want in Interface > clicks (I like 2 PPwr 3 edit and 5 off)

So, just wanted to throw some ideas out there... I've been too busy with sessions to do much real testing, but some thoughts:

I've been noticing my battery life has been diminished since moving to the new Imp body and stem system. Instead of the 3-4 bowls per battery I'm getting more like 2-2.5. I'm also noticing the new Imp body and stems get very hot very quickly. I know that's by design, but I'm wondering if the apparent efficiency drop is really worth it.

So tonight I went back to the old Imp body and stems for the first time since I got the new one. First time using the old system with my new TCR 105 resistance .254 "turbo" settings and whoooooa! It performed pretty surprisingly. It feels like it's running really hot and fast compared to the same settings with the new Imp system. I can drop temp 20° from my usual with the new stems to get comparable vapor. And the vapor is coming faster than with the new stems. Hotspotting is of course more of an issue than with the new design, but neither the body nor stems are getting nearly as hot in usage. Must be because the old body is thicker?

I widened the holes on the old Imp body to match the new body airhole size. Each cold hit is taking about half the draw time now it seems. I may be missing something and of course will keep comparing, but I have to think at this point the old stem system is ultimately more efficient.

Which batteries are you using off which mod? These powerhouse convection heaters suck a lot of juice but 2-2.5 bowls per charge..? My FF2 would get ~3-4 bowls from a 750mAh cell. I'm imagining 4-6 good sessions off 3000mAh. Same with my hopper off around 750mAh too

Using 1Ah for a single bowl seems strange, no?

Using a 3000 mAh hg2 I am getting upwards of 10 bowls, damn near all day usage, with the new body stem setup, on fj firmware, on a vtc mini. Out of all the 510 herb mods I've used, imp is by far the most battery efficient.

I use the same cell and same mod and I'm getting nowhere near to your 10 bowls mate. It's all a matter of usage pattern and bowl sizes.

@antispleen: I'm not challenging you. Just pointing out it's apples vs oranges when comparing bowl counts. I'm pretty sure like most North Americans you are more of a "one hitter quitter" kind, or at least, as few big rips as possible per bowl kind of person. Whereas I get 30+ hits out of the exact same quantity.

And it clearly shows in battery consumption, I need one order of magnitude more heatup and cooldown cycles to get the same result. Has been the case with every convection vape I own. And as the Tubo cruise mode proved, it's during these transitions that most of the energy is spent. You don't need much Watts to maintain a hit, but you need a lot to get there. And cooling down is pure waste.

@deadlytoaster: with a single 18650, whatever the vape or attachment I get around 3-4 bowls per charge. With least efficient vapes like the Milaana it's closer to 2.5, and with more efficient ones and by pushing the cell voltage very low, like with the Imp for instance, I can get closer to 5, but never more.

With the Nomad which is pretty efficient I also only get only 3 because the low power heater becomes so anemic when the cell reaches 3.6V it's a struggle to get that 4th session (but it's possible) So I stop at 3 while there's still juice left.

The MistVape Touch was also quite efficient I found. But now that I got an Imp it's gathering dust. The Milaana has been doing the same for even longer tho...

Very good points, and it's all in good fun, I wasn't trying to be hostile at all, I have a big grin. Yes, I tend to kill my bowls pretty quickly, which absolutely would explain the discrepancy in battery life.

I have similar use and bat life with @KeroZen, even lower. I like many draws from low temps to just before combustion.

@Improvize I am waiting for the oring version to compare. But I think Dave decided to change because the new system was by far more efficient ? Or satisfying, depends how you define efficiency... The thicker old stem was supposed on the contrary to need more heat sinking with the first draw.

Yes and I can even run it on a very small mod (with integrated battery) with great success. A tiny setup for sure. But no more than 4 bowls per charge, 4-6 hits per bowl.
This mod don't get a true TC mode but something called the Joules Mode, since I don't understand how it works I used it in power mode and, strangely, I noticed it works hotter than the Evic at the same settings,... so I lowered the power to 16W to avoid to scorch my load... Is it cause a bad connexion between my Evic and the Imp or is it common to have differences between the mods (if it was TC mode I could understand better but it's power mode!)??

Why can't I use the 14mm tapered stems in the new sleeve? They work ime.

Not all 14mm joints I have work but previous glass stems do. I can also confirm new stem has decreased battery life, still better than 3 bowls but not as great as my previous 7 minimum up to 12. Now it's more like 4 minimum, 10 max. Also a high temp vaper I'd assume if you're low temps your wattage on TC doesn't need to be past 30.

If you haven't used other 510 mods I'd say we are lucky cause Imp has had way better battery performance and longevity when trying to run on a single mod.

The benefit is that you can configure out everything from the PC. TCR, temp, temp dominant (+v), resistance lock, etc'.
Okay I've used AF and just wasnt happy with readout and interface is there a way for it to stop displaying Temp Protection when reached max temp. I ended up using NFE Toolbox and flashing the older Tubo Firmware for some reason the Official Joyetech software didn't want to patch it.

For those with AF compatible hardware not able to use current Tubo firmware I'd suggest trying it. Default firmware on these mods is actually pretty jank and AF/Tubo is the only reason to get these mods.

This firmware doesn't have cruise control or a few other cool features but did work for my Primo Mini in terms of improving use and experience.

I'm not going to stress usage stats enough to test them in an uber-scientific manner. The important thing to me is simply noticing what affects battery most, because with such a tiny system it can make quite a difference regarding getting through the day on one charge or not. There are a lot of variables that sway it considerably. The body/stem system you choose seems to be a big one, if not the biggest.

I'm down to 4 bowls with the P80 single battery mod and a 30Q or HG2 battery with the new body.
I'm sure I could get more if I were trying to cashe the bowl in 2 or 3 hits but I'm not in a hurry and enjoying the slower more flavourful extraction over 10-15 draws, rotating and maybe stirring as I go.

Someone from France ordered an Imp and some stems and I can't remember which user it is. I need to confirm info on the stems. I sent an email but haven't heard yet. If you are from France and are waiting for your order please dm me and we can get yours shipped asap (it is sitting in shipping waiting for the stems, but I have questions about the stems).

I haven't used other mods but the evic vtwo mini has been great. Battery life seems similar to me but I haven't really done a careful comparison. For me the new stem is just so much better, when I built the first prototype I really liked it and then it broke and while I redesigned it I so missed the O ring stem.
I had paytonpenn and antispleen test it and they confirmed my results.
So I think kerozen has a great point it is a personal experience and a lot factors come into play.

You think that the average user would be better using the TCR mode instead of Wattage? for avoiding combustion?

Which settings are you using? TCR?

I think tcr is the way to go. One user said he combusts with flower and only uses the Imp for concentrates. But he is running in watts on a smok al85 not tcr. I’ve never combusted with the Imp, never. All of my other vapes I've combusted from time to time.

I forgot to say 30W :)
Was set a little higher but the battery drains all the way to zero at 30W on the P80

So seems the penis stem has gotten a lot of comments. Your mind is in the gutter. Anyway i circumcised it.

My partner thought i should just put it out there and call the dick stem. . i opted not to go with her suggestion.
But this is phallic
