Temperature Control Testing Results: Smok Mag Custom SS TCR 75 (Decent when tweaked) https://ift.tt/30DdGab

Imgur version of post for those using old reddit, here: https://imgur.com/a/KQKCH1H

TLDR: Despite the questionable design, this is another good-for-the-price temperature control mod…but only only once TCR tweaked! Out of the box the SS TCR stock value of 105 was literally off-the-charts-too-hot. Using a custom TCR of 75 (the lowest I have seen yet) for the SS profile produced results that were not only largely accurate, but pretty flat and within a narrow band of the set temperature in most states. The mod seems to use a "smart power limiter" in TC mode that actually causes some slow heating for high mass, high resistance builds compared to a DNA (see https://imgur.com/a/EOL9hRE for max power output comparison).

PLEASE NOTE THAT THIS TCR FINDING UNFORTUNATELY DOESN'T HOLD FOR ALL MODERN SMOK MODS: I ALREADY KNOW FROM PRELIMINARY TESTING THE SMOK XPRIV BABY (SAME INTERFACE/SCREENS) REQUIRES TCR ~88 FOR A SIMILAR OUTCOME ON SS. Findings verified with thermocouple on this one.

The following represents the results of temperature control testing of the Smok Mag Stainless Steel built in profile using a custom TCR of 75, and standard coils shown in the table at the end. The conditions of each test are shown in the title of each graph. There did not appear to be any firmware upgrades available at the time of writing. A perfectly accurate temperature control result is the red line matching the yellow line.

For this first coil, low resistance, mid to high mass, vaped dry, without airflow (shown above), we can see some slight overheating with the mod hitting around 225C. There was a slight smell and light browning of the cotton, but certainly not a big fail; this the hardest state for the mod to contend with: very low resistance, completely dry. This is really the only test where its close to a fail. Seeing nearly 80W, not the 100W set, but close.

Here is a more realistic case, low ohms, wet, with lots of airflow. This might not be DNA flat, and we have seen flatter, but there is no way I can feel those little bumps when vaping on it, and its pretty much bang on. Fairly quick to hit temperature too. We never get the full 100W, the peak is about 75.

Here we have a mid ohm, dry coil, without airflow. As usual the mod handles the mid ohms better, much flatter line, and only slightly overheated, this is a pretty good outcome. No hint of burned cotton here. We only get around 70W before it pulls back, pretty much appropriately.

Mid ohm, wet, with airflow and more mass, we see the mod be is a bit conservative pulling the power back a little early, peaking around 60somethingW. Its pretty much spot on with the custom TCR though. Tiny bit of overheat as the as the airflow stops.

Here we have a high resistance dry wire with very low mass…it seems almost like the mod has identified a dry coil state with it pulling back on the power quickly, and an oddly noisy result (this is rig noise, but it indicates the mod is doing something different). It never gets close to temperature which is a good outcome in a dry state.

High ohm, high mass, wet with lots of airflow, we can see the the maximum power we get is under 40W, and it takes a long time for the coil to get close to temperature. When it does, it drops off the power too much to early before coming back a little weak. If this coil wasnt such high mass it probably would have been a great outcome. As soon as the airflow stops you see it kiss the set temperature and then do some more, good control. Definitely not a bad outcome but not ideal for high mass MTL.

Here we have the highest mass coil; a dual clapton coil, wet, with airflow and the temperature increased to 230C just to check if the settings work with a different temperature target – which it does. The maximum 80W is slow to get this very high mass coil to temperature, and again it pulls back a bit too much when it gets close to temperature, but when it hits, its a nice, smooth, flat outcome. Overall smooth and very usable, you just might want to pre-heat for a couple of seconds if want that set temperature for the whole draw and youre on a high mass dual coil setup going for temperatures at or above 210C/410F.

OVERALL: This mod DOES NOT work great out of the box, but a simple tweak to the TCR to 75 on SS mode produces an outcome that is smooth, flat and accurate in most states, with decent dry hit protection. Its not the best we have seen, and the mod is clearly a bit slower than say a DNA, and takes longer to hit temp and settle, but not so much that its a real issue. For a dual cell mod, this is one of the best we have seen under $75 (better than Innokin Proton).

The available power appears a little low, the mod pulls back on power a bit too much, too early (cheaper hardware is usually slower, therefore more conservative behavior makes sense). For the money, this is a pretty workable TC mod. It looks like the Smok XPriv Baby performs pretty much the same on TCR 88 based on preliminary testing, so dont take the 75 for this mod as being applicable to all smok mods with the same interface and screens. I will try to test some more smok mods so that there is a tested option that doesnt look like this mag does. I do think its indicating that you can get a smok mod with this kind of board behind it, and probably find a TCR with a thermocouple that will work to produce a good outcome. Some experimentation required.

Just because I couldnt believe how low the TCR was, I did do a bunch of thermocouple double checking on this one, and I consider it verified.

A huge thanks to u/VapeyMcGyver for designing and building a temperature control testing rig (anyone who wants to make one should contact him – its not expensive, its based on Arduino Due and some electronics knowledge). Info on the amazing work he is doing here: https://www.reddit.com/r/electronic_cigarette/comments/f99glv/custom_built_instruments_for_testing_mod/

Hopefully this is of interest to or helps someone – if someone wanted to replicate findings that would be ideal. If anyone wants the raw data dumps or analysis files for these data runs, please let me know – I would be delighted to share and talk about possible improvements. Insert infinite disclaimers; I cannot guarantee that the equipment and method of observation has not impacted the observed outcomes (in fact I guarantee it has). The testing rig has a range of strengths and weaknesses like any experimental setup and its accuracy is not guaranteed – some of the data points shown are "rig noise". I will gratefully receive all feedback and methodology critique – this is going to be about continuous improvement for a while. I have completed extensive testing of the rig to the extent that thermocouple testing is reliable, and I estimate that the rig is accurate to around +/- 7C typically (its hard to calibrate with a thermocouple, I would say thermocouple testing is only accurate within around the same range also, due to issues like thermal contact, and variation between the temperature of different wraps in a coil e.g. centre wraps tend to be hotter than edge wraps). Because I am close to the burning temperature of dry cotton I can usually tell when a mod has gone over 120C from the smell, and I can see that also in the rig results. It should be noted that my temperature calculations are currently using a fixed TCR of 0.00092, which may impact accuracy, however my testing has not indicated a discrepancy between a good mod's displayed temp, my calculator and thermocouple results yet, even for DNA mods, at the 210C level I am testing.
