cacole Why do you need to read the CVs? If you download the Tsunami Technical Reference Manual from the SoundTraxx web site you can look up every CV, determine what the default value is (or was) and proceed from there with programming new values without any need to know anything more about a particular CV.

Thanks for the suggestions, guys. I may look into getting a programing track booster.

Some systems will not read back Tsunami CV's with out a programming track booster.
A DCC Specialties PowerPax or the SoundTraxx PTB-100 should help.
Sound decoders usually require a higher current to read back than non-sound decoders, to the point where some command stations have trouble with them.
Tsunami's in particular are often noted for for this type of issue.
Assuming there isn't an electrical problem with the loco itself, or the installation into that particular loco, the decoder you're having trouble with probably had all it's component tolerances line up to put it at the high end of the "readback current requirement spectrum". In other words, the luck of the draw.
I have a Tsunami AT1000 EMD567 installed a little over two years ago in a P2K GP7 that work just fine but provides very strange reading from my MRC Prodigy Wireless program track. The engine's address is #1132 and it responds a performs fine when call up. When asked for address on the programing track it responds with either Err, 000, or 0064. Other requests for readings -- SV, Mid, TV, Acc or any particular CVs-- get the same responses, in no particular order.
I have three other locomotives with the same decoder installed at the same time, and they (mostly) readback with no problems.
Antbody got any ideas about what's going on?
