Yes!! yet another 2B Firmware update is available on the Developers/Support forum at http://www.e-stim.net
NEW: Ability to choose output level maps. We now have two different output maps, selectable via the advanced settings option. A is the same as 2.B005 and is the default, Map B is our more experimental system. The Map you choose is remembered when you turn the Box off. Reset either via the Advanced Option, or a factory reset.
If you want the firmware, then all you need to do is join the Support forum (its free) at http://www.e-stim.net and register as a developer.
