Good morning to everyone ( I'm in the uk). All is right in the world and I'm a happy man for the time being. Left the mini over night and she still vaping great this morning. Quick recap as I've been using it for last couple of days in power mode with some kanthal builds. Originally I tried various titanium builds and ego mega with clr ti coils and no matter what I did it would work fine until the first sleep. Upon wake up I would see a lower base resistance by about .04 ohm regardless of locking it in or not and the temp when first firing would show much higher that it should considering it had been idle and immediately hit the temp ceiling. Now I mean immediately no delay at all in fact if you blinked you missed the starting temp and saw the temp protect message. This caused the anemic vape and the watts while firing would be between 0-5w so I would have to raise the temperature ridiculously high or remove atty, fire, replace atty and choose new coil and lower temp or it would burn instantly.
Ok ran the 1.2 firmware last night and put on ego mega with clr ti coil which I had rebuilt with some 26g gr1 ti wire which came in at .36ohm. I set it to 230°c with the full 75W available as it's my understanding that with tc you need to get that coil up to temp as quickly as possible to get the best experiance. It did what it was supposed to do, temp rose sharply to 230°c within 2-3 seconds and displayed temp protect then the watts dropped off and bounced around between 10-20w maintaining the temp around 227-230°c resulting in a warm, rich clean vape. Ok so now the test, I put it down and left it for 10 mins and waited in anticipation. When I picked it up quick press of the fire button showed the resistance had dropped by .02ohm down to .34ohm, oh no I thought here we go again but the temperature that it displayed with that quick press showed 45°c not the usual 185°c I had been accustomed to seeing after a sleep. Vaped it and hallelujah it was working right on the money but not quite as good as b4 the resistance drop so raised it 10° to 240°c and there it was perfect, for me anyway. Im now of the belief that the initial .02ohm drop is down to some sort of refinement process similar to dna40 board as It has stayed rock solid all morning, even after a refill and forgetting to lock in the resistance b4 taking tank off. I got the new/same message went left/same and bang .34 ohm same vape.
I would like to think it was down to the firmware update which I had to run twice as it semi bricked after the first attempt but I've been running in power mode for a week previously and disassembled it a few times so can't be 100% sure it was but fingers crossed this is a fix. Got a lot more playing about to do with more builds etc but this is progress.
