yoseff Posted June 14, 2016 Author Report Share Posted June 14, 2016 I saw an answer in other topic that i tried and it works!It deserves to be seen by more people, so i took the liberty to create a new topic with it. It will be in quote, so the person who shared it, get full credit for it:gorman said:You can actually "cheat". You load the curve for Kanthal from Steam Engine. You'll see it's perfectly flat, with all the data points sitting at 1.0 coefficient. You leave most of them alone but start raising them by 0.1 after 392F°, 0.1 for every following point. You then select the new material for the VW profile, you instead opt for temperature control, set up preheat to your liking and vape. The circuit will respect the preheat values (I set the punch at 11, so it just erogates the preheat power for the preheat time duration), then, measuring the resistance and seeing it doesn't get higher, it will simply keep on outputting the max power you have set up.And that's preheat for non temperature sensing coils in variwatt. My friends: This actually is a solution, at least until implemented in firmware!To make things easier, i share here my already modded kanthal csv file.(Edit - Also added the ecigprofile i am using on my DNA. I think you can use it and modify to the preheat watts you want)Thanks gorman kanthal_Preheat.ecigprKanthal_A1_preheat.csv 1 Link to comment Share on other sites More sharing options...
dwcraig1 Posted June 14, 2016 Report Share Posted June 14, 2016 I was quite doubtful, I tried this with a few atties till on the 3rd it worked. Note cold ohm vs live ohms. Firing at 50 watts, 75 watts preheat. It works. Link to comment Share on other sites More sharing options...

retird Posted July 16, 2016 Report Share Posted July 16, 2016 Anybody done this with a Clapton Kanthal coil?dwcraig1..... can you add Temperature to the graph so we can see what the temp is doing relative to the Temperature Set of 550F?Gonna try this with Clapton set @ 425F and 27 watts to see how it deals with lower temp and wattage....

dwcraig1 Posted July 16, 2016 Report Share Posted July 16, 2016 OK give me a minute, I'd say that the temp is way out of whack though. Link to comment Share on other sites More sharing options...
dwcraig1 Posted July 16, 2016 Report Share Posted July 16, 2016 This is using a Vt133, single core 26 gauge Kanthal wrapped with 34 gauge Kanthal (dual coils) in Aromimizer v1.Firing at 70 watts, 110 preheat. Link to comment Share on other sites More sharing options...

dwcraig1 Posted July 16, 2016 Report Share Posted July 16, 2016 Gee I thought I did this on my 75, I couldn't get it to work earlier today on my 75. I see I posted a live view of it a few posts back. Hmm Link to comment Share on other sites More sharing options...

This guy wants preheat of 110w. Let's Give him. WAAAIT! There's some error! The csv must be wrong to this wire - pass to watt mode. Hum, a TC wire. This guy wants preheat of 110w. Let's Give him. WAAAIT! There's some error! The csv must be wrong to this wire - pass to watt mode. Hum, a TC wire. This guy wants preheat of 110w. Let's Give him. WAAAIT! There's some error! The csv must be wrong to this wire - pass to watt mode."And so on...Sometime my DNA gets clever and can remind what happened before, so he will give up of preheat. "You are so dumb! The csv is wrong. Let me pass to watt mode straight."In this case i will take out the tank, fire, and put it again. "New coil?" - Yes (if asked - some times doesn't). And i can fool him for some more time Please Evolv - do not make us fool our beloved DNA's. Put preheat available to watt mode on next firmware 1 Link to comment Share on other sites More sharing options...

randall Posted July 16, 2016 Report Share Posted July 16, 2016 I'm running the a Clapton build but no TC and there's a noticeable difference... Link to comment Share on other sites More sharing options...
retird Posted July 16, 2016 Report Share Posted July 16, 2016 dwcraig1... thx for the graph.... surely the preheat is effecting the coil temp even tho the graph is not showing a temp rise during preheat.... and ohm's reading in the graph is showing cold ohms? Wonder if having the temp set to 450F is effecting the vape as it is within the "flat part" of the "curve" and the 0.1 rise starts at 482F in the "curve"....Gonna have to play with it a bit..... THX again dwcraig1.... Link to comment Share on other sites More sharing options...

Try it and if it works, you will feel a huge difference: High watts to fast ramp, and desired watts to maintain the flavour Link to comment Share on other sites More sharing options...

(at least i think that way, but always learning)I'm just pondering the graph results as opposed to the preheat being shown in the graph..... no doubt the preheat has to raise the coil temp during preheat. Gonna play with temp set above and below 482F and see how it effects the graph results. But that's for tomorrow as it's late here..... Link to comment Share on other sites More sharing options...
randall Posted July 16, 2016 Report Share Posted July 16, 2016 @youseff Most definitely. I've been using it all afternoon and it really make a HUGE difference! Link to comment Share on other sites More sharing options...
Mdelaere Posted July 25, 2016 Report Share Posted July 25, 2016 This might be a silly question, but why do this? Is it to make sure the coil is quickly at a nice temperature to vape? Personally I never had much issue with that, just wondering. Currently breaking my head over my SS316L TC settings. Link to comment Share on other sites More sharing options...

Claptons, Alien coils and so on, need a lot of watts to "wake up", but then it can be too much watts to maintain the heat you desire. Less watts will get you there, but then the ramp up time will be more. With preheat, you get more watts to start, and less to maintain, achieving a better vape experience.With SS316L you can have preheat, but on most of the times you will not need preheat on SS, as it ramp up pretty quick and then DNA200 will have an hard time to control the temperature due to SS316L low tcr.

dwcraig1 Posted August 10, 2016 Report Share Posted August 10, 2016 So my Kanthal with preheat didn't seem to work with SP3 so I went back to "recommended" and it worked. But then I flashed it back to SP3 and preheat with Kanthal works. This is with a DNA200. Link to comment Share on other sites More sharing options...

We_Said_Destroy Posted September 10, 2016 Report Share Posted September 10, 2016 It is awesome! Running it at 85 watts with a 110 preheat on a DNA200. Heats up my dual fused claptons nice. Better flavor. Nice job. Link to comment Share on other sites More sharing options...
