Smok cube 2 ohm issue

So I was just given a smok cube 2. The guy gave it to me because the ohms were reading way to high like .8 instead of .25. So I took it thinking I might be able to fix it realizing it was probably an issue with the 510 assembly. I had a similar issue with my crown tank where mods didn't register a coil but I disassembled the pin I got it to work properly. In that case the pin was pushed to far down (after having dropped it) and by adjusting it the coil would then register.

My friend had dropped the smok tank and suddenly the ohms weren't reading correctly. I immediately assumed the pin may be pushing too hard against the pin on whatever given tank. So I pushed it down. The ohms started to go down, much closer to the correct ohms. I got it to acceptable range, kind of - .33 instead of .25 - which I then could manually reduce to .28 which is within usage range .. I think? I tried to push it down farther. Bad idea. Now it's jumping up to .6 to .4. I'm thinking off disassembling the mod and taking a look at the 510 pin. Do some research on how a 510 should look like set up properly.

That, or buy a new 510.

Can I fix this 510? If I can, suggestions on how? If not, can I replace it? If I can, where can I buy a new 510? How involved would the process be? How expensive?

Btw I do realize that saying it's acceptable for the ohms to be off is stupid. If I fire my tank with .25 at 110 watts versus say .33 at 110 watts there's a big difference in amps. Not to mention is the coil even functioning properly? That's an obvious no. Even using an ohms law calculator to figure out the proportion of what 110 watts would be at .33 is unsafe. --------my goal is to make the mod read the ohms correctly---------

To be honest, unless you plan on fitting the 510 yourself, it won't be worth it. It will also be quite hard to install a quality 510 on an Xcube 2. I would keep it as a backup and get it as close as you can reading wise.

In relation to your second part, in regards to the Ohms being off and safety, you will not be in any danger with the resistance reading off. Resistance plays no factor in regards to amp load on your batteries in a regulated mod, only your wattage does. There is no difference in amps at 0.2 vs 2 Ohms on your batteries at 110W.

At 110W, you are fine as long as you are using 20A+ batteries. You may have to reduce the wattage a bit though, as it will be sending a higher voltage to the coil with the incorrect reading. For TC, this would be a big issue, but for standard Wattage mode you can just reduce it and use it as it is.

I DO plan on doing it myself, I realize that having it done by someone just wouldn't worth the cost for such a mod. I like projects. I do have some skill with my hands, I've built PCs, done soldering, even fixed with crown's 510 thingy. Could you elaborate on why it would difficult to fit a new 510? Also, I'm starting to think it may not be the problem, or only part of the problem. I do vaguely remember my friend saying the issue with the incorrect ohms reading occured after he had dropped it. However, I read someones post who had the same issue - too high of an ohms reading - and he brought to some electrionics guy who discovered there was ejuice that had leaked into the mod and was on the circuit boards. He cleaned with some solution and it immediately resolved the problem. Of course, I've noticed there appears to be ejuice underneath the screen on top. Maybe that's the issue.

I used an ohms law calculator: http://www.steam-engine.org/ohm.html

.25 Ohms at 110 watts is 5.24 volts with 20.98 amps
equivalent .33 ohms is 83.33 watts, 5.24(same volts), 15.89 amps (the amps appear differ, thus my concern. Although the amps appear to be lower, not higher, which in that case would be a problem without proper batteries - right?)

Even with this calculation, I can't shake the feeling this isn't 'driving' the coil properly. I've tried vaping it at 83.33 and it 'seems' about right in terms of warmth, cloud production etc. My gut is that this isn't safe.
