  1. When using Replay profile "Watts" is the material to select but you must use TC capable wire for the coil.

    In the TC profiles Replay can also be selected, in those profiles you select the material that you are actually using.

  2. If your coil works in TC then it is most likely TC wire.

    Use EScribe's Device Monitor to see if the resistance of the coil changes when heated. My example is using SS430 wire which has a greater change than SS316,

    Replay must 1st be enabled in the profile in EScribe and use TC wire but depending on the theme it may need to be enabled their as well.

  3. First off Replay box on profile needs to be checked. Depending on the theme Replay needs to be activated from there as well, this situation had me going nuts for awhile.

    Maybe save your theme and try another theme, coil wise I think it should be working fine.

  4. For what it's worth. The mod resistance on my two SXK Billet boxes are set to 0.011 ohms. They were measured using my shorting tool. One came out to 0.010 and the other at 0.011 so I set them both at 0.011 ohms.

    Contact area need to be clean 1st.

  5. Here are some situations that wreck havoc on getting TC to work properly especially when using wire that has little resistance change when heated. Things need to be pretty much perfect for these wires to be read properly by the board.

    !st.  is a coil with shorting wraps giving a false cold ohm reading, as the coil starts to heat the shorting may stop creating a jump in resistance.

    2nd.A bad connection between the 510's, maybe atty's 510 is too short or has dirty threads on it's 510 threads or loose to wire post.

    3rd. Wire not clamped under post screws tightly.

    4th. Wrong TCR settings.

    There has been some cases where LV put thread locker on the 510 threads where the ground wire connect internally on the 510 socket creating a problem with resistance readings. This was quite some time ago and I have not heard of it since.

    Just to name a few, I'm sure there's more

  6. Here is a snippet of my 2 cell DNA200 firing at 80 watts (set to 80). I was going to ask you to post the same of yours when I seen mine doing the same.

    Here is why mine only reached 66 watts and not 80. All of the DNA boards that use cells in a series are buck only meaning that their output voltage will never be more than battery pack voltage. In this case the 200 board powered by 2 cells has a maximum output of 6 volts.

    Note in my snippet that @ 66 watts the output voltage is maxed out at 5.96 volts (blue line), if I built a lower resistance coil it could hit 80 watts with the right resistance.

    Could it be that you have the same thing going on?

    The max voltage on a DNA250 board powered by two cells is 6.2 volts and the 250C is in that range also.

    But looking at your build I doubt if that is your problem.

    I would like to know what your pack/cell voltage drops to when firing. 6.88 v in my snip.
