Had some kanthal laying around and wasn't sure what gauge it was, I'm guessing it was 30. I did an 8 wrap microcoil that came out to 1.1ohms. Does that sound right? Wicked with cotton. Getting very good flavor, good throat hit, and good vapor production. However I thought 1.1ohms wouldn't fire on an evic? Does this mean there is a short somewhere?

No... it's unlikely - unless the diameter was well less than 1/16" - that you could get 1.1Ω with 30 gauge at 8 wraps. On a 1/16" mandrel at 8 wraps, off the top of my head, you would need 27 gauge Kanthal to obtain that resistance.

This will tell you why it's unlikely that you either are not at 1.1Ω - or you've misjudged the wire gauge.

Ga...... Ohms/ft./in. @ 68F
24...... 2.04 - 0.17
26...... 3.31 - 0.28
27...... 4.15 - 0.35
28...... 5.27 - 0.44
29...... 6.55 - 0.55
30...... 8.36 - 0.70
32...... 13.1 - 1.09

Many APVs will fire below their suggested minimum resistance. It all depends on the microprocessor programing - and level of accuracy in deciding what is acceptable resistance, and a short. They won't necessarily deliver beyond their amperage limitations, but they may fire a few 10ths below specification.
innokin APVs are notorious for firing several 10ths below their 1.3Ω suggested limit, but as they are regulated to 3 amps, going below that resistance is of no advantage.

Flux, that was, hands down, the best explanation of gauge resistances I've ever seen. You win the internet for the day :toast:
Golly gosh Papa, I've never won the entire internet.

Does anything useful come with that title?
