Try creating a custom kit. I did for my Dr880 and Yamaha Edrums. I use Superior Drummer, but EZD is similar.
Each drum midi note corresponds to each kit piece.
C1 might be kick
D1 Snare
C2 Rack tom 1
etc.
When you highlight a kit piece in EZD, look at the corresponding note. Click on the drum kit piece. Assign the note you want. For example if your kick is on C2, Set it to C1. Click the kick and see if the sound is what you want. Do that for all toms, cymbals etc. You can save that as your own custom kit in EZD.
If you can find a map for it, that's easier. I didn't see any maps for Sonar when I went through this.
