Vaporesso Forz “Smart TC” Tested…Not so Smart? – SS316L Temperature Control Testing Results https://ift.tt/3aCbTs0

The above is the first of 7 charts/states tested and does not represent overall performance – scroll down for full report and analysis, or the TLDR summary. See a full list of mods tested so far, at the end for comparison.

TLDR: More questionable temperature control from Vaporesso on the new Forz mod, actually worse than the Vaporesso Gen, where the regular TCR mode produced better SS316L temperature control results than this "Smart TC Mode" on this Forz (which is the only apparent TC choice on the Forz maybe I missed it in a sub menu somewhere, but the menu on this thing is crazy). Lots of cotton burned during testing on this one. It is generally inaccurate and overshoots, then giving a somewhat bumpy ride in most tests (except very low ohms, where it overshoots but then becomes accurate after a few seconds). We have seen worse results, but we have definitely seen better results in the price range (e.g. Geekvape Aegis Solo/Max/Nova/Mini noting that other Geekvape mods did not perform well because they dont use the Nuvoton chip). One has to wonder if a more extensive chain vape test might reveal something interesting on this one given the result found when I started and stopped for the high ohm dry coil below, it did seem to learn from its earlier massive overshoot (further research required, and I will be doing that on the Gen S shortly).

============================

The following represents the results of temperature control testing of the Vaporesso Forz Mod, using "Smart TC" mode. The conditions of each test are shown in the title of each graph. 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), there was a lot of smoke and the cotton completely burned. No flame at least, so there is that. I re-ran this test a couple of times to be sure. It is repeatable.

Here is a more realistic case, low ohms, wet, with lots of airflow. It hits more than 240C before dropping back to about 175C, which is terrible, but by around 2.4 seconds in it has settled down to a reasonably smooth outcome, that is also reasonably accurate.

Here we have a mid ohm, dry coil, without airflow. No hint of burned cotton here. Actually decent dry hit protection in this mid ohm state.

Mid ohm, wet, with airflow, we get a much worse outcome than on the dry coil, with the temperature outcome being very much under the set temperature.

Here we have a high resistance dry wire with very low mass…wow did we get some burned cotton on this one, I had to stop the test to prevent flame. BUT then I fired it again during the same run, and the mod does seem to have "learned" to lower the power on this one, but the cotton is already burned to a crisp, so not very useful by the time it has learned….very bumpy but not too inaccurate here.

High ohm, high mass, wet with lots of airflow again we get the mod producing a way under temp outcome, bumpy and inaccurate. Unusable.

Here we have the highest mass coil; a dual clapton coil, wet, with airflow. Unfortunately we only get about 40W out of it so it never reaches temperature. Not very smart; this coil wanted the full 80W (see the same test on power mode here: https://imgur.com/a/RuHi6Gm)

OVERALL: Again, Vaporesso delivers poor temperature control results, this time using their "Smart TC" mode. It doesnt seem particularly smart, or at least its not producing accurate outcomes, dry hit protection in some states, or a smooth temperature outcome. For the same price you can get much better results from other mods (Vsticking VK530 or Geekvape Aegis Solo/Mini/Max/Nova which are using the Nuvoton chip)

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 rig he has built 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.
