The "Restore Defaults" button under the General tab will set it to how it left Evolv's facility. I recommend saving your existing settings first (File/save as) as a backup.
Just highlight the materials and note the values of the graph. If you put up the window to change it the settings for Ni (or last setting made with EScribe stilll open) will show but nothing changes till you push "OK"
By using Device Monitor in EScribe you will be able to see the standing voltage and voltage under load of the cells when firing. It be good if you could post what they are. There could very well be a problem with the connection between the batteries and battery contacts or perhaps with the cells themselves.
That is how mine is also. There were some corrections made to SP5 so perhaps that reflects that. I really don't know. Edit: from the Early software page "[SP5a fixes a few minor EScribe bugs in SP5.]"
Welcome Tamer, the board is quite efficient but watts is watts. The LED is not there like on the 75. If your concerned with EScribe settings for your batteries... well that will only make your battery gauge more accurate. The cell soft cutoff though can be lowered from 3.09 volts to 2.8 volts.....that will give you a bit more.
Not to worry, the mod is faster than the screen. It knew what the resistance was so it didn't need to ask. Look at it firing in EScribe device monitor to see.
I don't have any first hand experience with that but here's what I think. The ribbon is soldered on to the board and while it can be replaced it takes considerable skill. The extension cable will have to be fabricated or a similar ribbon modified and soldered to existing ribbon and board. You should be able to purchase a new screen for the DNA 20 by opening a ticket with Evolv. https://helpdesk.evolvapor.com/index.php?a=add
Are these the coil heads that you are using? http://www.vaporifics.com/aspire-cleito-120-maxi-watt-coil-0-16ohm-5pk/ They are stainless steel. Are you using them in temp mode or power mode?
You will always have 8, what you can do would be to make profiles 3 & 4 the same as 1 & 2. Do the same with 5 & 6 and 7 & 8. That way you will always have your desired change one click away, either up or down.That's about all that can be done,
