If you execute this in the JavaScript console you'll see that it does
indeed dynamically reflect the value you type into the EtherText tiddler:
$tw.wiki.extractTiddlerDataItem("EtherConfig","damp")
So, I think the issue is that your simulate() function isn't getting called
when you expect. It looks as though maybe the simulator is only receiving
the value of 'damp' at startup via the initenv() call.
