Ah fair enough, when I tried it, it just remained at 1.091, I assumed it was because it wasn't 'erasing' the old one firmware properly since it just seemed to do one 'pass' when flashing...

Yeah if you read up a bit that's exactly what happened to me - the new tool erased the settings but didn't apply the new FW.

A proposed fix for it by @TheLordWinter was to first enable the Download mode on the mod itself (last entry on the Settings menu I think), then proceed as you did with the upgrade tool. I will try that next time I do the update. That's what he did and the new tool worked for him. Though if that is the proper solution it's ridiculous the new tool doesn't list that as being required in its list of steps.

Thanks for posting the original tool

Well titanium seems to actually work a lot better in nickle mode with a TCR of 0.00750.

Kinda pointless buying titanium mode at the moment.

If that's true then their TCRs are completely broken.

The only difference between the modes should be that it enables different parts of the TCR scale. So SS enables 0.008 - 0.0015, Titanium enables 0.0015 - 0.004, and Ni200 enables 0.004 - 0.008

Which is rather convoluted and dumb, every other mod with TCR adjustment just gives you a single scale. It is good for newbies that they give SS vs Ni vs Ti modes, but it's daft that the TCR is only part of the scale in each mode.

They could have had four modes: SS, Ti, Ni, TCR. With the first three not having an adjustable TCR and the latter having the full scale, perhaps with the TCR visible but non-editable in the first three. Or they could have allowed TCR adjusting in all modes, with the default at the preset value for that mode, but still allow full adjusting up or down. Anything but what they've done.

Anyway, a TCR of 0.0075 should be heating your Titanium coil to slightly over double the target temp. 300°C on the scale will be around 625°C, 230 will be around 470°C, etc. Or perhaps 10% lower than that because of the underheat. (And of course with a wet wick you won't actually reach, say, 470°C - but it would/should on a dry coil.)

If it's doing anything different to that, things are very broken! I'll test it tonight.

Honestly Bloke I've got no idea with this mod, on the titanium setting I literally couldn't get any vapor at all under 400°F, it just wouldn't fire.

I've slightly lowered it to 0.00700 and I'm vaping it at 340°F and it's giving a better vape than I ever had in Ti mode, no hint of burning etc.

Yeah! It is incredibly variable, because that definitely does not apply to mine. In Titanium mode, mine is pretty reliable and normal - except it underheats a little, so I need to set my desired temperature about 10-15°C higher than I do on other mods. That's an improvement in 1.092 versus 1.08, where it was 20-25°C.

Several people have reported incredibly flaky results like yours. @Mad Scientist took his apart and found wiring problems on the 510 and fixing that improved things a bit, though he still felt it was pretty flaky after that and he eventually gave up and turned it into a DNA 200 ;)

So I wonder if yours has some sort of internal HW problem.

Have you compared the resistance readings it gives to other TC mods? Do you have other TC mods that show resistance to at least two decimals, ideally three? If it is reading your resistance much higher than other mods that would definitely be indication of 510/wiring issues, and would explain having to set the temp (and/or TCR) much higher than desired.

All that said: although of course it should produce some vapour below 400°F in normal Titanium mode with TCR 0.0035, 400°F is still very low. 450°F is my usual setting on an accurate mod, and on the Smok I had it set to around 480°F on version 1.08. Now I have it around 465-470°F on version 1.092. It's not at all surprising that 400°F wouldn't give a good strong vape on a properly working Smok; though it should produce some vapour.

If I set my coefficient to 0.0035 and my temp to 500°F I get what can only be described as a faint whiff of vapor, at 0.0055 it seems to be performing in a more respectable manner at the temperatures you quoted.

I checked out the 510 yesterday but couldn't find any signs that anything was loose, if anything it seemed rock solid.

Have you compared base resistance readings you get to other mods you have? Do you have any other TC mods that display resistance to two or three decimal places?

Nope, this is the only tc mod I have at the moment.

I've rebuilt coils for it on 3 different rta's and a Velocity, some multiple times.

If I'm doing something wrong I'd love to know what it is because I'm stumped.

OK that's unfortunate. There could be a variety of things wrong. If it were any other mod then we could say it must be the build. On this mod we can't rule out the mod itself.

But the fact that you've done multiple coils does reduce the chance of a basic mistake.

What're the details of your current Titanium build (wire gauge, number of wraps, internal diameter, approximate leg length between coil and posts ) and what resistance reading are you getting?

At the least give the base resistance reading, the one shown on screen (and to three digits in Settings -> Adjust Initial Ohms) when not vaping, but ideally can you also hold fire and watch on screen and see what highest value it goes up to? You can also see that on your phone/tablet if you connect via Bluetooth - though it only updates once a second and sometimes, at least for me, doesn't pick up some vapes.

It's some 26ga T1 from the crazy wire company. At the moment on my Taifun GT2 I've got 8 wraps on a 2.5mm bit, legs are ~5mm and it's reading .336ohms.

I've tried spaced and contact, I'm not priming the coils in any way.

As an aside, the during-vape resistance reading is possibly useless. I had way too high figures in SS mode (showing the coil was at up to 900°C), and I just checked in Titanium mode and it showed a 0.281Ω coil increasing to 0.53Ω. That should indicate the coil is heating to 270°C, not the 240°C the mod is supposedly limiting to. Besides which there's no way it's actually heating to 270°C.

The resistance reading for a 0.281Ω coil increasing to 240°C with TCR 0.0035 should be 0.496Ω, or 0.50Ω rounded to two decimals.

Putting the mod up to 250°C and the resistance peaks at 0.55Ω, indicative of 290°C (0.545Ω) - 300°C (0.5549Ω)

We know the mod underheats - albeit seemingly a bit less on 1.092 - but I still can't understand these figures. It's not underheating by 40°C by any means.

I'm going to temp test it now with Ti.

Which is completely correct. Hum. Well first impressions have to be it's something flaky on the mod, as you're certainly not the first to report it.

Can you see what the on-screen resistance reading is during a sample vape? In normal Titanium mode, 0.0035 TCR, and set to 450°F or 230°C. Just to see if it's showing even more weird than it usually does.

Oh, are you on 1.091 or 1.092? I seem to recall you mentioning an upgrade problem. It shows the FW when you turn it off and on again. If 1.091, then definitely go to 1.092 so at least we're checking the latest.

1.092 software using the beta upgrade tool.

It's going up to .62 when I fire it at those settings but producing no vapour at all.

0.33Ω -> 0.62Ω is indicative of a temperature rise to 270°C. That pretty much matches the resistance rise I see on screen for my current 0.281Ω coil, set to 230°C or 240°C (the same at either setting.)

So I can say the bizarro on-screen description of your Smok matches the bizarro on-screen description of my Smok. What I cannot say is why you're getting no vapour.

Try the following: Take the atomizer off the mod, with no atomizer on press fire so it says Check Atomizer, put the atomizer back on (if you've recently fired it, wait 5 minutes before doing this step), press fire and it will ask New Coil?, to which say Yes.

Confirm if the resistance reading is still 0.33Ω, and confirm if it still produces no vapour.

If it's the same, then I'm sorry I really don't know. You could try another build in a simple device like an RDA, being absolutely certain it's fully tightened down.. But it sounds like you've already done that multiple times.

Okay... On the app under the titanium setting there is a variable power slider, what should this be on?

That disables TC mode, putting it into VW mode. The Smok doesn't have precise wattage control under TC, it only has MIN/SOFT/NORMAL/HARD/MAX - which I believe does cap the maximum wattage at different levels. Any of them should produce vapour, but use NORMAL for now to match my settings.
