  • @Tina Thankyou for looking into this. I have done what you have suggested but this has made no difference. I have taken some pictures to illustrate this: My daily MTL tank is the Nautilus-X. Below are all of my NX-75 mods. I know! I love them!

    image



    The first image (below) up Is my Grey NX-75-A Which is firmware V07. This reads 2.04 ohms.
    image



    Next is my Silver NX-75-A. This has the factory installed firmware (never updated). This reads 1.87 ohms.
    image



    Then it's my NX-75-S. This has the factory installed firmware (never updated). This reads 1.84 ohms.
    image



    Then it's my other NX-75-S (Heavy things aren't they :) This has the factory installed firmware (never updated). This reads 1.85 ohms.
    image



    Next is my NX-75-Z (Where my love affair started!) This has firmware V05 installed and reads 1.85 ohms.
    image



    And...finally my Black NX-75-A. This has the factory installed firmware (never updated). This reads 1.97 ohms.
    image

    As you can see, the first mod (grey) has a reading much higher than all the others. The only one comes close is the last one (black) but I'm willing to admit it's probably unscrewing it and rescrewing it that may be changing the reading. I have tried downgrading the grey one with all the other firmwares available and it just doesn't make any difference. It isn't the tank either. I tried another tank with a 1.05 ohm coil. The grey one read it at 1.22 ohms. It's as if some other component inside the mod has been permanently flashed and won't accept a previous firmware.

    I would really appreciate Aspire's help on this one as I really do think these are the best single 18650 mods on the market. I know people have said that it's just a reading. I'm not sure. The grey one does appear to need more power (wattage) to achieve a similar vape as all the others.

  • Hi, is there any news on this? I have 6 NX75s (Yes I know - I love them!) - I have updated one of them to Firmware - 07 and it doesn't matter if I downgrade it, my tank is reading approximately 0.2 ohms higher than the others that haven't been updated. I'm not sure why...
  • @ruben It 's my pleasure to answer your question
    ruben
  • I wish aspire would stop saying no problem there is a problem...my build for Kayfun reads 1.38ohms and has done ever time I build it but after 07 update it reads 1.51ohms
  • Great update!

    However I have a possible bug report; I upgraded from the factory installed firmware 02 (just recently bought the NX75), and the Ohm reading is now different from before while using the same coils (Nautilus X Tank, 1.8 Ohm coils). Before update they read around 1.81 - 1.84 Ohms, now they read as 1.92 - 1.99 Ohms. The same tank and coils still register as around 1.8 Ohms on my other brand backup MOD.

    Temporarily reverting to firmware 02 did not revert this behaviour :-(

    This could IMHO have adverse effects on the coils if too much power is fed into them due to an erroneous Ohm reading. Any advice / explanation?
  • Feature request: Please add showing the used voltage depending on selected Watt setting in W mode.

    Addendum to my original comment:

    Example using Nautilus X 1.8 ohms coils rated at 12-16 watts and setting the NX75 to 12 Watts in W mode:

    If the coil is actually 1.8 ohms but the NX75 reads it as 1.95 ohms, the watts will most likely be off.

    The MOD should fire at the 4,8373 volts that are required to get a 1.95 ohm coil to receive the selected 12 watts, but instead you'll end up with 12,9997 watts, as the resistance is actually 1.8 ohms - Almost 1 watts difference!

    If the MOD has instead been set to 16 watts, the MOD will fire at the 5,5856 volts that are required to get a 1.95 ohm coil to receive the selected 16 watts, but instead you'll end up with 17.3333 watts, which IMHO most likely will affect the lifespan of the coil.

  • Same issue can someone from aspire please comment..let us know if this is going to be fixed

    @dobermann @sputsnick
    What issue ?
    Your box does not care about the resistance that is in the clearo.
    If you ask the box to give 15W it will combine the Voltage and the Current from the battery cell to give you the Power you requested.
    The Ohm's law calculation you use (P=E²/R) is only valid for full mech mods, with an electro box, only the P=E*I must be applied here.

    So, what the NX75 measures for the resistance is only informative and will not cause any issue.
  • Ok that my be true ...so let's just put it another way ...the ohms reading after the 07 update is way off
  • Well, hey, I'm gonna chime in here and say, hey, this is super awesome. I just inherited a very well-worn NX75 and the idea of a mod with "firmware" is like... holy crap, what? New features on something already released? Mind = blown.

    Very cool, appreciate the update, it's working great for me (at ~0.6 ohm), and the update process was stunningly straightforward - a very well-designed utility (running Win10 x64 on a USB 3.0 port, Intel controller) and a brilliant update mechanism that seems to require no drivers. Awesome.
  • I've also noticed the ohms misreading after going from V06 to V07.

    Another issue I have with V07 is that the button lock is not working anymore ("W" & "+"). After reverting to V06 it's working again.
    Did anyone else also have this issue?
  • You mean the "key lock/unlock" function ?
    Never noticed because I never use that feature; but indeed, doesn't seem to work with me either ("W+" or by menu).
  • @Bas In firmware V07,all the functions are under "w+t" menu mode
    the key combination mode is not working in firmware V07

    Correction : it does work with the menu (it's me that needs a user upgrade ... :\"> ).

    :))
  • I found a bit of a bugger here. See, it seems that you can turn the "menu" function on/off when you run what I assume is first-time setup. When you hold the fire button while putting the battery in, you're prompted for three things: one, you're given the firmware version (not so much prompted there), then you're prompted for En/Cn language selection, then finally you're asked if you want to use menus or not.

    Mine was set without menus at first (coming from V02 firmware). Enabled it, and now I get the fancy menu everyone is talking about. So if you don't get the menus and are disappointed, try that - hold the fire button while putting the battery in.

    @FalconFour different firmware version with different functions.
    aspirecig.com/upgrade/nx75/
    For original Firmware v02,it doesn't comes with menu function

    @Cegoca
    I strongly disagree. Do you have any references for this claim?

    In my understanding, the box needs to know/measure the correct resistance of the coil in order to calculate a correct voltage to be applied for reaching the requested watts.

    The formula P=E*I only applies when both voltage and amps are known, and a regulated MOD as the NX-75 does AFAIK not directly apply the raw voltage provided by the battery (depending on charging state), but instead uses internal circuitry to step the battery's voltage up or down dynamically depending on actual battery voltage and with respect to calculations based on the resistance of the coil combined with the selected wattage.

    I stand by my claim that a wrong Ohm reading is a potential issue and that the Ohm reading on my NX-75 was different before updating the firmware.
    From other posts in this thread, it seems that other users have also noticed this change in Ohm reading.

    If the NX-75 would show the voltage applied when firing, given a specific wattage and resistance (like some MODs from other vendors do), it would be easier to verify correctness of the internal calculations.

    It may be that the ohm reading is actually correct now compared to the reading before updating firmware (my cheap standalone multimeter device is not precise enough to verify by measuring the coil directly), but a consistent reading of around 2.0 Ohms (or sometimes more, up to 2.2 recently) for several (more than 7 by now) original Nautilus X coils rated at 1.8 Ohms is IMHO a notable difference for a premium priced MOD like the NX-75. As stated earlier, the expected 1.8 Ohms for my Nautilus X coils were read by the NX-75 before updating...

  • References ? Only logical thinking from confirmed users on forums that certainly matches some of the Wiki crap or other "specialists" articles you can sometimes find ... :D

    The electro box in a setup must be counted as a separate circuit (with its chipset cheating on the Ohm's law ?).

    An example :
    Set your mod at 40W and put a clearo with a 0.5 Ohm coil on it, you should have a nice vape.
    Now, the box still set at 40W, put another clearo with a 1.5 Ohm coil, it won't change, you will still have a 40W vape and will probably destroy your coil ...
    Why didn't the box change the power when the resistance tripled ? Because it can't, just as simple as that.

    So, again, the box does not use the resistance to calculate anything, thus its differences in coil measurement will not impact your settings.
    And your so called issue is irrelevant.
  • @Cegoca

    I didn't say anything about cheating Ohm's law, please read more closely what I wrote, and maybe read the references instead of just dismissing them as 'crap'.

    I also never wrote that the mod will change the power (watt) when using a different resistance coil. It will change the applied voltage in order to meet the set wattage, and of course you'll burn through a coil when exceeding it's specified watt range (as in your 1.5 ohm coil example), I never stated the opposite.

    I have a realworld example:

    My other brand backup mod shows the applied volts when firing in addition to the measured ohms, and I have also seen other mods capable of the same.

    With a coil measured as 1.42 ohm and mod set to 11 watt, it shows 3.99 volts applied when firing.
    With another coil measured as 0.58 Ohm and mod still set to 11 watt, it shows 2,82 volts applied when firing.

    I have not changed any setting on the mod, just switched coils.

    How will you explain the difference in applied voltage other than that the mod reads the coil resistance in ohms and tries to meet the selected wattage using ohms law?

    I have asked for applied voltage shown to be added as a feature to an upcoming firmware upgrade for the NX-75 in order to be able to verify correctness of the internal calculations. My backup mod actually applies a wrong voltage to meet the selected 11 watts for the 0.6 ohm coil. For the 1.4 ohm coil it's pretty much spot on.

    Can anyone from Aspire maybe chime in on this thread and comment on the changed ohm reading in the updated firmware? And also maybe confirm that my feature request for showing applied voltage when firing is noted and maybe will be considered for an upcoming firmware update?
  • My Macbook doesn't recognize my NX 75. I can charge the battery but upgrade is not possible. Any advice?
  • @ottobyte Hello we have checked the firmware V07 again,we don't find the issue you mentioned above.
    But we found a little bug on firmware V07 for SpeedBrake function,We have updated the firmware aspirecig.com/upgrade/archon/467.html
  • @ruben which firmware version you downloaded has this problem?
    aspirecig.com/upgrade/nx75/
  • @Tina
    I got it. Sorry for disturbing you. Sometimes it might be useful to read the manual first. :\">
  • @Tina Unfortunately that cannot be the case - As I said, I have 6 NX-75's. On the same Nautilus X tank with a 1.8ohm coil, 5 of my NX-75's read 1.87. The one that has been updated reads 2.05 ohm in wattage mode. Is there any way to completely wipe the firmware and start again?
  • Hi, I was just wondering if there's any update on this. I am a bit peeved that I cannot change that firmware to fix the ohm reading. Please help!!
  • @ottobyte Our QC and engineers have checked twice,we don't find the issue you mentioned.
    here is the firmware V07 for NX75.
    Please try download and update again

    And for that same thank, what does an average ohm meter say ?
    On what FW do each of your NX75 run ?
    (btw, nice collection ! ;) )
