DCC 2-6-0 in the future?

That's some great info!  So with the Tsunami there is no sync. set up?

[peterherron]

Well, not exactly!!  There is no sync issue between throttle, engine speed and chuff as the same decoder controls both speed and chuff, but you must sync the chuff rate to the locomotive's drive wheel rotation, i.e. 2 chuffs/revolution.  This is a snap compared to trying to sync the acceleration in one decoder to the chuff rate acceleration in the other or vise versa!!  I hope to try again tonight and will report on progress.

It's four chuffs per revolution.

One double acting cylinder per side two exhast strokes per revolution
two cylinders = four exhaust chuffs per revolution.

Bet you knew that.

Tim,

My honest answer??  I really thought it was 2!!  After I read your reply I went to Google/U tube and found a couple of videos the clearly show it's 4!!  As I need to tweak the rate to get 4, it will be much simpler in the 1 decoder 2-8-0 vs the 2 decoder in the 2-6-0!!  Without a drive wheel cam on the 2-8-0 it has to be a bit of an approximation.  I've found if you get it right at speeds slow enough to see the 2...er...4 chuffs/revolution you really can't tell at the higher speeds.
