Have been looking at the Snd equipped 10 wheeler since it came out,Can anyone tell me' does it come with light steam or med steam sound?
All I could find in the Bachmann Quick Start Guide is the decoder is matched to the type of locomotive.
Rich
Where did you find it? All I have been able to find is that it will be available in May...
All I found was the Bachmann quick start guide, not the loco. The document was buried in the SoundTraxx site.

Do not know if it is still valid.
Rich
If anyone acquires one of these, can they tell me if the chuff sound is synchronized or not.
Since all the other Bachmann/Tsunami OEM installations are not sync'd, I don't hold much hope, but maybe they have worked something out in the interim.

The chuff is not synchronized. I have the Spectrum 4-4-0.

Thanks Rich,
I was going to trade my non sound locos in on a few new Tsunami versions, but if the chuff is not sync'd, there's really no point.
I might buy one of the Quantum Revolution systems & see if that will 'chuff in time'. Using Bemf, they are pretty good on the BLi's, so I may be lucky there.
Cheers.

I believe you can adjust the CV for chuff rate. I have not seen what CVs can be adjusted with the Bachmann supplied sound loco. I know the Tsunami's I installed can be adjusted to match the cylinders, though the chuff rate is not linear. If I adjust at a slow speed, as I increase the throttle the sync changes. From what I have read so far, sound decoders cannot be syncd at all speeds. You need a cam for this. The Micros I installed have a external sync capability. Others may have some input.
Rich
A tsnumai can be tuned by altering a few of the CV's and the chuff an be synched better. It would take to long to explain so if you followthis link this explanation should iron out the wrinkles.

That's true.
But unfortunately, the OEM Tsunami's chuff rate is linked to the throttle & not the anything the loco is doing.
I have corrected the chuff on several Tsunami OEM locos, but as soon as you apply any load [incline or cars]; or remove any load [decline] the throttle position is changed & therefore the chuff is running at a different rate.
So I guess, if you get rid of all that boring stuff like freight & passenger cars, shunting, inclines etc - I mean, what's wrong with running your Tsunami OEM loco light, on a billiard table smooth flat surface?.......?

Yes, this is true. You can put the tender on the track and open up the throttle and watch the tender do nothing but it sounds like it's doing full speed.

Yes, and there is no smoke coming from the smoke stack or steam from safety valve or whistle.
Sometimes no engine crews either.
Rich
Seriously though, QSi, MRC & ESU OEM installations chuff at, or very near to, the correct rate.
So maybe I am expecting too much from Tsunami OEM - though not according to their advertising.
Anyone who has a Blackstone K27, knows just how good a Tsunami can be when the chuff is sync'd.

You don't actually have to remove the loco, just add a load & listen to it chuff it's smokebox off, without turning a wheel. ;)
it's not linked to throttle position but to motor load. Change the load on the motor and the chuff rate will change slightly as will the timbre of the exhaust. While the the Tsnumai OEM is laid out differently to a Tsnuami all the Cv's are the same except for whistle which has only 3 selections instead of the normal 7. By tuning the decoder CV's 2,3,4,5,6, 116,209 and 210, whose default settings are a compromise to allow the loco to run. By further tuning these CV's the running qualites will be improved.

G'day Charles,
I'll have to disagree with you on one point. CV 116; the Auto Exhaust Rate, is not controlled or related to any Bemf signal. If that is the case you cannot attain a sychronised Chuff Rate across the speed range. CV 116 is linearly proportional to throttle setting. You can apply a Speed Table, CV25, but this again is only an approximation & not connected with any Bemf input.
Mark, this is quite true but as I said it is prportional to motor load based on voltage and yes if you tune a few more Cv's that I haven't mentioned you can get the chuff closer still. You cannot get it to be exact by using this form of electronic method. I generally use some form of cam be it electro mechanical or optical. On the Bachmann locos this can be done b by fitting an axle mounted cam or a wheel mounted cam. Other ways that are slightly more complex is by using an optical sensor or magnetic reed switch. These methods require more ingeniuity on the behalf of the modeller as in most cases extra space as to found as well as magnets for the backs of wheels to provide the magnetic influence for a reed switch.
The axle mounted cam is the easier method but due to Bachmann's insulated wheels and small diameter axles it makes it slightly more difficult to mount. The easiest method, if slightly unsightly is to use a disc mounted cam similar to the Soundtraxx cams These can be glued to the back of the wheel. An electircal path has to be provided and some form of pickup mounted. This can all be done quite quickly and you can a synchronised chuff in afternoon.

G'Day Charles,
That's all good advise & would certainly go a long way to attaining sychronisation.
I do think it unfortunate that Soundtraxx could perform a relatively simple rewrite of the Tsunami firmwear, & the Bemf signal could be made available for the Auto Exhaust to use, solving the problem for everyone.
To take the ball to the try line, but not step over & score, always seems odd to me.
