Model Railroading > Tsunami Question

Hello Group:

I am familiar with Tsunami 2 & Econnami decorders and can get locos equiped with either to play nice together (yes, I know, EVERYBODY can!) however
I have one loco with what I would call a Tsunami 1 or First Generation Tsunami that I cannot get to work with T2's or Econonamis no matter what I do.  Is there
a difference between the early Tsunamis and the T2/Econamis and the T1? 
I want the T1 loco to be programmed to match the later Tsunami decoders and not have to adjust down later generation Tsunamis to match the T1. 
Should I dump the T1 decoder? Is that the best way to make all these locos play nice together?

Thanks,

To my knowledge, it's  as you say, you can get Econami, TSU2 and Blunami to work with the Tsunami 1 but not the other way around.  Which makes sense. An Econami is basically a much improved  Tsunami 1. Open to  any corrections
