Whether you'll need a programming booster depends on the type of DCC system you are using. I have read several comments here about certain DCC systems not being able to program the Tsunami and/or QSI sound decoders without a programming booster.
I use a CVP Products' EasyDCC system to program these decoders and have never had any problems or need for a booster.
I just installed a Tsunami in an IHC 2-10-2 and could not program it on the programming track. I use the MRC Prodigy Advance. Once I figured out what I was doing wrong and with a little help from members of this forum, I was able to get it programmed on the main line using the Prog Main option.
I did not have this same problem with my BLI E-7 though. Programming track worked as advertised for this locomotive.
Hi, Goat!
I installed Tsunami's in 4 Spectrum Russian Decapods, a P2K USRA 0-6-0 and a brass PFM A&LM 4-6-0. They are easy to install and work/sound great. Eventually all my steam will have them.
I discovered that my Digitrax Super Empire Builder set would not allow me to program them. One CV would "take" and the next not. I had to get a Power Pax from Tony's to solve my problem. Now I can change any CV I need to with no trouble.
Enjoy!
