Setting the Exhaust Chuff Rate with Tsunami2 and Econami Decoders

With Tsunami2 and Econami Digital Sound Decoders you don't need a cam to get the perfect chuff timing out of your steam models! That's right skip the cam install and simply change a CV to keep you chuff in time with the drivers.
CVs used in this video:
CV 114: Engine Exhaust Control
Adjust the cadence of the exhaust chuff to match your locomotive’s wheel rotations with CV 114. Entering values from 1 to 255 into CV 114 will determine the chuff rate. High values indicate more rapid chuffs, and low values indicate less rapid chuffs. CV 114 should merely be used to bring the chuff rate in line with wheel rotations. Setting CV 114 to a value of 0 will disable Auto-Exhaust.

GG- Gorgeous George 👀,
What a fantastic helpful & easy to understand video tutorial on setting engine chuff rates so simple. Keep edumacating us Dcc procrastinators with your vast knowledge of your products. Thanx Thom...

[@imaginenonn37]

very informative

[@SoundtraxxDCC]

Thanks for watching!

George, I'm a "cammer" and not convinced about the Tsunami 2. Could you show the chuffs after setting them running at different speeds? I've watched YT videos with the T2 and it sure seems like the chuffs vary according to speed. Maybe if one runs the engine at the same speed all the time it works but that's not realistic for most engines. Could you maybe add the cam wire to the T2 for those wanting the cam?

[@SoundtraxxDCC]

It works really well! Watch this one and see what you think: czcams.com/video/5W7jaeor4oY/video.html

If I were to install a TSU-2200 into a DCC ready Proto 2-10-2 how will it be able to read the rotations of the motor without adding an additional sensor?

[@harryhenninglll117]

Do we still have a way to put a chff cam on our engines if desired.

[@SoundtraxxDCC]

No, because this renders them unnecessary.

[@harryhenninglll117]

Hi George.
With us running these in O scale with smoke it is necessary to have to match up with smoke chuff.
With your board how can we have these match in sink.

[@bonanzadriver7261]

Nonsense. The chuff will still drift up or down. I have spent hours adjusting cv114 and it will not hold. I’m tired of screwing with it and have pulled out my Tsunami 2 and gone back to my old original Tsunami with the cam wire. Installing a cam on a driver is NOT all that difficult and the chuff stays spot on ALL the time.

Hello,
Have you contacted our Customer Support Center for help with setting this feature up? This was a feature that we did not take lightly (especially in eliminating the cam wire option), so we operated this in many different models before the final firmware was approved. We did not see this ‘drift’ that you are referring to and this has not been an issue brought up by our customers using this feature either. Sometimes it does take changing the value by 1, and in some cases, you can even play with the speed table slightly to help make sure it adapts.
We want to help you fix any issue you are having with the decoder but the comments section is not the place to do this. Will you please contact our Customer Support Center so they can talk to you a get to the root of your problem quickly? When you contact them I suggest having a list of the CV values you are using and have tried and what model. And be able to explain what you are stating about drift up or down actually means.

I have tried moving the adjustment by one in either direction but over time the chuff still move. What the locomotive sits for a while then is called on the drift is more noticeable. Additionally I want the chuffs to be at 12, 3, 6, and 9 as the real locomotives chuff. Impossible with these. You could have left the cam option but chose not to. I have used Tsunami sound decoders in my Sn3 locomotives since they became available however in the case of the Tsunami 2 I’vet chosen not to.

Does the chuff rate synchronize in your large scale Blunami decoders?
