See what happens when you talk to me Barry? You'll never learn! 
I think we can agree that there will be a problem if users acquire the WIU and start adding engines to that, without consideration for their remotes.
That would lead to the remotes not finding the engines where it thinks they should be.
I'm searching for why I lose associations to TIUs with engines that I purposely keep the addresses in the correct place, when I upgraded the TIU's software.
Barry stated that there maybe something or maybe not. I wouldn't shove words into his mouth!
address #9 does not come up in my extra 3rd remote. #9 did come up in my dedicated G scale remote as a lash-up with 2 Dash 8s that are outside. Those would have been run with this TIU#2 last summer.
#9 is a SD70ACe in my O scale remote running with TIU#1 that is not powered, and did not have the WIU connected to it.
So where did the phone see a ghost engine in address #9????????
