Hunch or on to something?... I made another coil, just purely testing. Ohms reader - 0.22 DNA 250 mod - 0.219 aaand Drag X mod - 0.20 So my current stock coil, the VM6 reads at bang on 0.15 in Smart or RBA mode. They have 3 different Direct Lung colis listed on their site at 3 different Ohms of 0.15, 0.20 and 0.30. I have a feeling these are the only options a DL coil will actually read at on the mod??? What are the chance that my 0.22 coil read at 0.2 and my 0.42 coild read at 0.30... its almost like the mod can detect its a D.Lung coil or RTA and just 'pre-sets' to the closest option. My 0.22 coil vapes OK cause its close enough to the 0.20 option on the mod but my 0.42 coil does nothing cause its wayyy too far off the closest preset of 0.30 This could be a complete coincidence and speculation... can anyone who has this mod + RTA confirm if yours can read builds outwith these? @ikes above seemed to have something very similar where the mod seemd to know a few different possible ohm options and just wouldnt read anything apart from these.
