I've got a TFV4 Mini on a Wismec Reuleaux DNA200. I decided instead of using the normal TF-N2 coils, I bought some TF-STC2 coils! I really wish I hadn't! Anyhow after burning up a cpl I realized my Reuleaux needed an upgrade! So now it's set to ss316 & I've got it set at 70w 550°, max! It works, but very quickly exceeds the temp & produces a tiny amt of vapor! I'm wondering if there's a patch or if anyone has a tip on custom settings I should use, or any other solution! Thanks.
