I have a new Athearn Genesis SP 4-8-2 with Tsunami TSU-1000 decoder. I’ve changed the CV settings according to recommendations by Caboose Hobbies in Denver, as indicated below. Using my NCE throttle, the locomotive runs backwards in the forward direction, and forward in the backwards direction. And when I advance the speed from 0 to 1 unit , it flys down the track. Can someone help me correct this. Thank you.
Caboose Hobbies recommended cv settings for this locomotive:
The engine running backwards indicates that you have the decoder plugged in wrong if you used the 8-pin NMRA socket – turn the decoder plug around to correct this problem.
Another option is to use CV 29 to correct the direction problem by adding 1 to the value. The value in CV 29 to tell the locomotive to use a long address, 28/128 speed step, and no DC operation would be 34.
In a previous thread, Athearn recommended the following decoder values:
These settings are originally recommended for the Tsunami decoder that is in the Athearn SD70ACe, but other users have indicated that they improved the steam sound also.
I am using the new settings as posted above in all my Tsunami units. IMHO the sound is greatly enhanced. I just infinished installing a Tsunami in a Western Pacific brass 4-6-0 using a high base speaker and I really had to turn master sound volume CV down quite abit. It used to be for me anyways that the horn/whistle volume was the weak spot. No more.
Sounds like CV2, start voltage, got set to some high number. Set it back to 0 to start, if the loco doesn’t move on speed step 1, gradually increase CV2 until it moves at the slowest speed it can reliably do.
