The coil I'm using is a Vaporesso, GTI 0.40 OHm mesh coil.
Your coil is a 0.4 ohm coil. It's reading correctly on your mod.
A 0.4 ohm coil should never read 0.17 or 0.22 ohms.
Unless . . .
A) a coil wasn't installed properly
B) the mod's electronics perhaps have an issue
C) perhaps you had a bad batch of coils
D) maybe you had a bad, or dirty, connection between your tank and mod
