iTaste MVP v2 Owners Group

OK, this makes NO sense... I contacted both innokin and 101vape about my issue. 101vape got immediately back to me and suggested I try the 1.8 ohm coil rather than the 2.2 I had been using.

Needless to say I was extremely skeptical as I thought it wouldn't make a bit of difference... It worked! The draw is back to where it should be and it's screwed in all the way. Not sure if I built this coil (measures out to 2.1), or if it was just thrown in with my washed coils but it worked.

I am stunned.

Like you said, that doesn't really make sense. I would bet it was the fact that while you were messing around with it, you managed to get the pins to contact better. Changing the coil .1 ohm should not change the air flow.

Edit: actually, even what I typed doesn't make a lot of sense. Glad it is working for you though

 

[liquidzoo]

I didn't think so either. It makes no sense to me now and it made even less when it was suggested to me. The 2.2 I was using measured out to 2.3, but even still a .2 ohm difference shouldn't have made any difference at all.

I do have a question about the mvp2 and it's PWM. I was looking at another thread about"absolute dc output" devices. Of course the provari came up, but blah. They started a list on devices that had high PWM. The mvp2 was in that list.

I know the ego style vv's and the like have a 33.3hz pwm chip, but no one ever states the pwm frequency of the MVP.

Anyone happen to know what it is?

All vv/vw devices use PWM. Even the ProVari. Provape states in the FAQ that they use PWM. The difference with the Provari is that the PWM is filtered on the output so that it does not pulse.

The MVP2 and iTaste vv3 also filter the PWM on the output. If you look at the output signal of a ProVari, MVP2 and iTaste VV3, they are almost identical. Checkout the reviews of these devices by pbusardo and he puts these on the scope...No PWM on the output.

That is why the MVP2 and VV3 are so nice. The MVP2 and VV3 do NOT rattlesnake.

No one is saying that the MVP2 and VV3 is a ProVari. The quality of workmanship of the MVP2 and VV3 is nowhere near that of the ProVari. However, on vape quality alone, the MVP2, VV3 and ProVari are frightfully similar.

I think you missed the point of the question regarding the pwm...

I do not think there is a hz rating on the PWM on the MVP or vv3. It is filtered so that when you put it on a scope, nothing appears.

Look at the pbusardo videos and his scope does not pickup any cycles. So what he is saying is that there is effectively NO PWM on the output.

Either that or it is EXTREMELY high, so high that on a scope it is essentially a flat signal.

that has to be the case. The thread I am referring to (http://www.e-cigarette-forum.com/fo...ods-have-absolute-dc-output-like-provari.html) notes the provari is 800hz. The evic is 100hz. There has to be some documentation somewhere with the mvp2 output frequency. I dont have a scope or I would check it myself.

What makes you think it's PWM? It probably is, because that's how modern high efficiency voltage converters work, but a quick look on a scope only shows noise at lower frequencies - I suspect it uses something like an LTC3113, which can be setup with a switching frequency from 300 kHz to 2 MHz.

so, you are implying that the MVP 2 has a output higher frequency than the EVIC and the ProVari?

Just ordered a MVP 2.0 to keep my VV 3.0's company. Merry Christmas to me

 

[Patkid]

well very nice, new MVP owners - congratulations ! !

hope you enjoy them and some friendly advice :

- don't screw your toppers on to tight
- and don't drop it on your toe

- 510 Battery to eGo Atomizer Adapter

AND DO NOT DROP IT ON YOUR iPAD SCREEN.

 

[Capt.shay]

Ouch!

should I NOT ask how you know...

Some days I am too stupid to vape...........................
It was a bad day.....a bad, bad day.
I had to pray my way through it, I am ALMOST to the point of being able to laugh about it.
Not quite.

Got mine in yesterday. Sold for life. It is the Dodge truck of APVs: tough, dependable, long lasting, and can tow (fire) anything, so I shall name her Dodge.

I call mine "The General"....



He's the leader of my 3 vv3 Innokin Army.

Much to the chagrin of the ProVarinati He's the main reason I don't have a ProVari in the mail....

 

[SoaFung]

Here here. While I'm sure the provari is indeed a nice device, the MVP 2 is all I need now.

so, you are implying that the MVP 2 has a output higher frequency than the EVIC and the ProVari?

No, although it may. Are you thinking it's a pissing contest and it matters?

No one is implying anything.

If you look at the output of the Provari, MVP 2 and the vv3 on the scope it looks like flat DC. How that is achieved, is really irrelevant.

PWM is used in boost circuits to increase the voltage output of a fixed DC source. In the case of the less inexpensive mods, this is done at 33hz or 48hz and it is both visible on a scope, audible, and some people claim detectable in the vape.

On the MVP 2, VV3, and ProVari, either the PWM is occurring at such a high rate that it appears flat on a scope, or there is additional filtering done on the output signal to flatten it out. However it's done is not the issue.

Bottom line, when you put an MVP, VV3, and ProVari on a scope they look identical. And if precision electronic measuring equipment can't tell the difference, neither than our less calibrated bodies.....

thanks for your input. It really brought a lot of depth to the conversation.
