Setting the Exhaust Chuff Rate with Tsunami2 and Econami Decoders

[@wrakca6049]

Trying now to adjust mine on a 2-10-0 .what do you actually look at to adjust where the cylinder rod goes into the the chamber?. I’ve always had problems adjusting to get close

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...

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?

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?

It works really well! Watch this one and see what you think: kzbin.info/www/bejne/a4iam5SbpNdnpbs

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

[@SoundtraxxDCC]

No, because this renders them unnecessary.

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.

very informative

Thanks for watching!

[@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?
