Throat hit too hot with a Lambo 4.0 - what am I doing wrong?

[niktemadur]

Hey there guys and gals, neophyte vaper here.

Around Christmas 2012, I ditched my old Camel Wides for an eGo-S mid-size ecig, and with absolutely no cravings for analogs after a month, this week felt like a good time to take things to the next level. Went into the store thinking about an eVic, left with a Lambo 4.0 and a Nova tank system with the 510 to 510 adapter.

After a day of trying to find the "sweet spot", it's proving to be elusive, hopefully somebody can share their experience and put me on the right track.

The facts:

• Clicking the activator button 5 times gives the resistance - 2.0 ohms.
• The atty head on the Nova should be the "1.80 ohms".
• The E-Liquid is 24 MG nicotine level, Full Flavor (still just vaping tobacco flavor so far).
• Like an analog, I vape in long, slow drags straight to the lungs.
• During first day of Lambo usage, batt charge has gone from 3.8 to 3.6 - sounds ok to me.

The experience:
The throat hit can hurt on the Lambo, while it's just fine on the eGo-S mid.
Fiddling with the voltage, even 4.0 feels too hot, so I'm keeping it down to 3.6, but the vape is funny when colder, with a faint taste of, I don't know... icy synthetic berries, how's that for a subjective description. Anyway, it's not entirely pleasant.

Maybe the nicotine content is too high on my E-Liquid for the Lambo, but that shouldn't be the case, should it?
Could switching atty heads in the Nova tank system, to increase resistance, make the vape more enjoyable with 24 MG E-Liquid?

One last thing, before dehydration comes up, I drink plenty of cold water all through the day, always a bottle nearby when vaping, at home or on the road. That and an ice latte (two espresso shots) with soy milk. Good stuff.

Thanks for your time!

I'd try the higher resistance Nova heads.

I would suggest starting with 3.7V on the Lambo and see how that does...

And also I wouldn't draw straight to the lungs. There has been some posts on the forums that suggest the proper way to vape is to draw into the mouth. At that point you can inhale (I do) and it's not as harsh as drawing straight into the lungs...

24mg Nic level is going to give you a stronger throat hit anyway, so initially try using 3.7V as your starting point... Draw into mouth rather than lungs, if neither of those improve your experience, try a juice with a bit lower nicotine content to smooth out the throat hit, or use a juice with a higher VG content, as that can smooth out the throat hit as well.

toying around with the resistance may change things, but you'll still be playing with higher voltage at that point to get the flavor back. You'll probably come to find that you eventually end up vaping at a similar power level after a change in resistance on a VV device. What I've found is that for every juice out there, I have a range of around .3V that fall into my desired flavor / heat zone. Any higher and it's burnt and nasty, and less and it's too cool and unsatisying.

Keep playing around with it, and try out the suggestions I mentioned... Just don't give up on vaping

It's also worth mentioning that some of these juice manufacturers just don't make very good juice... Especially the Chinese juices. No offense to Chinese folks, but they just don't like the same flavors we like on the other side of the planet. The first juice I bought was a tobacco flavored 18mg juice and it was straight nasty. I picked up a tobacco flavor from Heather's Heavenly Vapes, and it was wonderful... So it could just be that the juice you got is just plain nasty, and nothing you do on your end will make it any better.

The exact same juice has been just fine with the eGo-S...

...even when vaping straight with no layover on the way downstairs.
So it seems to be neither the juice nor the technique, at least with the eGo-S.

Try a juice with a bit lower nicotine content to smooth out the throat hit, or use a juice with a higher VG content, as that can smooth out the throat hit as well.

Lower nicotine AND higher VG at the same time sounds like a win-win, in any circumstance.

You'll probably come to find that you eventually end up vaping at a similar power level after a change in resistance... I have a range of around .3V that fall into my desired flavor / heat zone.

So far on the Lambo, it either tastes fine but it burns, or it tastes weird with no burn. I didn't specify that on the original post.
...then I just did a straight hit with the eGo and it's perfectly smooth with no weird flavor. The sweet spot.

Just don't give up on vaping

That is NOT gonna happen.

Maybe you are just finding out that you don't care for the Vivi Nova? They don't appeal to everyone, that's for sure...

I find they give the best flavor right after topping off... Can you attach whatever your juice delivery method for the eGo-S is onto the Lambo at 3.7V (Around the same voltage as the eGo) and see how that hits? And vice versa, put the Vivi Nova on the eGo-S and see if it's any different.

It could be that what you're experiencing is the difference between constant power delivery, an pulse width modulated power delivery... Does the Vivi kind of rattle a bit... Instead of a constant hiss, it's a pulsed broken rattle type of sound? I believe the Lambo uses PWM, meaning it fluctuates rapidly from 0V to 6V is a square wave... It turns itself from off to full power enough that the "average" voltage is whatever you have it set to. The amount of time it's on (at full 6V) would be considered its duty cycle... So at 3V, it would have roughly 50% duty cycle... A lot like the fuel injector of a car...

Some folks claim to be able to taste a difference between PWM devices and fixed output devices. I personally can not...

I got it! It WAS the resistance, changing the atty to the 2.4 ohms did the trick, now I'm doing some spectacular vapes at 4.2 volts, with all the throat hit and flavor, no burn. Sweet spot!

From your help, dam718 and Shilo, I'm guessing the 1.8 ohms atty tasted good in the store because the Lambo/Nova combo had a lower nicotine content, the girl in the counter let me try her setup with her E-Liquid.

Now the eGo-S goes into the glove compartment of the car, it's now officially my mobile kit.

Next step, fiddling with lower nicotine content and higher VG.

Holy cow, the vapes on the Lambo are beautiful.
Thanks a million, guys!

One last post on the subject, last night I fiddled with the atty again, this time tried the 2.8 ohms at 4.1 volts, and I've gotta say "Wow!", even better than the 2.4 ohms atty, all my expectations have been exceeded. So now it's official - my Lambo is the bee's knees, the monkey's eyebrows, the kitten's ankles, the cat's particulars, etc.

Low resistance is really for pvs at 3.7 volts or lower - a way to get a warmer vape. With a mod like the Lambo you don't need it. Glad you've found the right match.

Ive not used a 4.0 but its vary possible it is not calibrated correctly it could use a cheaper circuitry that dumps pretty much raw power to the coil. If you look at a well built mod on a scope there smooth signal with a climb to your selected setting a cheaper one has a choppy almost instant voltage fluctuating over and under the selected setting.
Id suspect you are having this issue you should be able to use a LR coil with a lower setting and get the same results as the one with a higher resistance at a higher setting.
Some mods you just have to figure out the ins and outs glad you have it working to your liking.
