Put the engine on your program track and write a value of 8 into CV8, then power-cycle the engine for about six seconds. It will now be re-set back to factory specs and respond to 2-digit address of 3.

I have a Digitrax Zephyr DCS51 system if that makes any difference at all. Thanks for all your replies.
Why not just place each loco on the programming track as maxman suggests and reset to factory default? You don't need to know the long address to do that.

What DCC system do you have? If it is NCE then you probably are running them consisted using CV 19. If that is the case, then you can put the locos, individually, on the program track and set CV 19 to zero. Assuming that you were wise enough to set the original loco addresses to the number on the cab, the loco shouild run on that address when you set CV 19 to zero.
If you have a Digitrax system, someone else will have to advise you how to determine what the consist address is and how to break it up.
This will be easier than resetting the decoders.
However, if the above does not work, then you will need to put the locos on the program track individually and set the appropriate CV to the appropriate value. Forum folks can advise you what the CV and reset values are, but you will have to tell us what brand decoders you are using.
(edit: just re-read the thread title and see that the decoder is a Tsunami)
What DCC system are you using? I know with NCE you can browse the consists and maybe figure out what address you were using as it will tell you which engines are in each consist. You can do that without the engines on the track. Also did you keep address 3 active or did you disable it? If your system has an emergency stop button you can use that to stop the engine and then I think (though I am not sure) you can reset the decoder.

I recently ran into a bit of a problem when I wanted to run a couple of my Intermountain Gevos after a few months of not running them. It seems the last time I ran these two engines in particular they were lashed up under a certain address and a couple of problems have come up when I tried to run these two engines again.
First I lost the addresses to both engines and furthermore, the last time I ran these engines I must have turned off the power while they were still running so now when I put them on the track they run and I cant stop them because I forgot the address number that they were programmed under.
I would like to reset the decoders in both engines but I am not sure how to do it if I dont have the address to locos. Is there anyway to re-program these two engines without having the addresses?
