My Big Boy was set to Eng #1 from the factory and I left it at that.
I loaded its orange memory module into the remote per its manual.
I set Eng1 to 1 and pressed the SET button and that assigned the BB to E1.
No issues in running the Big Boy.

I highly suggest never leaving any engine at ID 1 or trying to use 99. Too much risk of unexpected operation if you go to a club or decide to add a second TMCC/Legacy engine. When TMCC first came out I ran my new engine on the layout at our club. I had left mine set to 1, I powered it up and had 4 engines take off including one that ended up in the turntable pit. And on newer Legacy engines 99 is a Universal ID that is hard coded
Great info!!
Thanks for the tip, I will reprogram to some other number.
I guess you have to check with your club on what numbers are used before you power up.
