Gentle Friends,
A quick update on the 'jumps out of TCR into VW mode on it's own' thing if you will? As you recall, this prevented us from using TCR on the Gen 1 carts. It might go a time or two, but without warning it would leap into VW mode and run too cold to make vapor or try to combust, depending. And running in VW mode is a PITA for modest results.....no doubt a factor in customers staying away in droves.
Enter the much improved Gen 2. I found the problem happened less often with say Pico, but it still happened once you stopped watching for it....... Nano was the same (as would be expected). Not reliable. However, VTC Mini never missed a beat. I ran mine on several Minis and my VTwo Mini. Later, when I got one, on the Basic as well. I've been using mostly on a Basic in fact.
It seems Murphy got me. "The statistics of small groups" was used to set me up? My original Gen 2 gave out a while back and Matt quickly replaced it. It was a preproduction one Matt sent me for evaluation with a V3 order. It was easy to see what happened, one lead from the heater was too short to make reliable contact. The post was discolored because of the heat generated. Good clue. But it didn't get me to question my earlier experience like it should have.
When it did dawn on me to recheck I found that the Pico and Nano can indeed drive the Gen 2 reliably, at least so far. It's a classical issue, when did the ghost move out? When have you seen your last random failure'? In troubleshooting it only counts if you can define (and hopefully demonstrate) the 'root cause' of the failure and then show how you've prevented it from happening again. Then you get the raise. Or so they say.........
So here's my idea, still basically the same. Unreliable instantaneous changes in contact with the heater is read as a resistance change (which I guess it is......) that can push the 'temperature reading' out of range and trip the 'revert to VW' protection. It's confusing because Mini is less sensitive to these changes than Pico. I've discussed this a time or two along the way.......it will be on the test......
My backup (which I ordered as soon as they became available of course) and the replacement from Matt didn't have the dicey contact from the hand built evaluation one I started with. That contact (the defective Gen 2) was good enough to fool Pico (or Nano) 'most of the time' and Mini or Basic all the time. I had a marginal unit and didn't know it. 100% of what I had at first showed fine performance on one brand and less problems (but still happened) on the other. Evic good, Eleaf bad. Bad assumption, I set myself up. Having found a later failure I didn't question the prior results......didn't see if the ghost was still there. I just continued to avoid that side of the street. I was younger then.
What are others seeing with theirs? TIA
So I find that (at least?) 2 out of 3 Gen 2 carts run fine on the same TCR mods most of us are using for V2.5 and V3? Although I am having fun with the myevic software and all the fun stuff you can display on the larger screen on Mini et al. Using a "m value" of 245 (same as V2.5 and smaller V3 in fact.....) with a power setting of 24 Watts I go from cold to vapor ("390F") in about 15 seconds. The myevic software lets you dial up 25 seconds, but the 10 second limit on the Eleaf mods calls for cycling the power. But they do a great job. The little Nano is smaller than the Gen 2 cart, and fits in your pocket like a dream......
Thanks for listening, anyone with some experience to offer? And those V3 guys with TCR mods who haven't bought into this should fix that part. Cold to vapor in 20 seconds on a pinch of herb? What's not to like?
TIA
Well, OK, not quick.....but it is an update and 'is what it is'.
