Turn off BEMF in the Titan decoder if it is on by default, and that should stop the lurching at low speeds.
If it does stop the lurching, I would suggest you need to figure out how to restore the BEMF function for proper acceleration in CV3 and to configure the various parameters that allow you to take advantage of the capabilities afforded by active BEMF. It works wonderfully in Tsunamis if people take the time to get into the book and to fiddle with values in CV's 209 and 210. LokSounds seem to come wonderful...eh, Tom?

Mine came today and it is indeed a smooth runner
Runs OK on my 22 radius but a lot of overhang
Anyway I bought it for my Articulated collection in my display case not to run on my layout
Wish Bachmann would do an Allegheny for the price of the EM1 as an alternative to the overpriced Rivarossi
I would get one tomorrow

Hal-
The first place I would look into are the PID settings, most likely 'I'. It is extremely rare on QSI decoders to have the BEMF cause surging. And this is after hundreds of installations and decoder tunings....

Very nice. Now open the tender and let us see what is inside. I am wondering if Bachmann is using the NMRA recommended color wires/what type of connectors?

Found this video on U Tube. While I love the music, wish it had a sound decoder in the engine.

I did read in the Bachmann forums about the 21 pin decoder. Just curious what the inside will look like.
Also I am seeing Tsunami Technology for the decoder. Some say NOT a Tsunami decoder but has Tsunami Technology on board. Not sure if the waters are being muddied. Bachmann is not forth coming with much info and the info seems to be scattered. The Bachmann rep at the forums is usually quite cryptic with his replies.
One user wanted to dim the headlight a little as he though it was too bright. That cannot be done until the sound decoder is installed according to a reply from Bachmann.
Also curiuos on how used will install their own decoder as the connection I hear is 21 pin. Have not looked at which companies sell a 21 pin sound decoder.
I'll have to agree with you about the Tsunami's sounding "stacato" like at the higher chuff rates.
From what I can tell, the steam cut off (Johnson bar controlling the valve cutoff) isn't accurately modeled. As a result the sound is cut off too early. Their algorithm should account for the train running in "company mode" (early cut off/most efficient use of steam) at higher speeds.
So far only the QSI Revolution (with software update) /Titan accurately models the steam valve cut off modification. But programming the QSI is such a pain in the DUCKASS. And it does sound noticeably better to me, but only at higher chuff rates.
That said, none of the manufacturers still make a really good steam at low speeds. If you ever watch a steam engine starting from a standing stop, you will hear very long "Whoooooses" as the cylinders dump steam. None of the sound decoders to date duplicate this wonderful sound. We just get a short "Short Chuf <long pause>Short Chuf<long pause>" instead of a proper "Whoooosh <very short pause> Whooosh <very short pause> Whoosh"
I'm still waiting for a decent quilable whistle (AKA playable whistle) too. Only Lionel/MTH seem to have done a good job at this. :-(

I am able to get the sound of the cylinder cocks being opened when my QSI equipped steam engines start out. After putting in the upgrade chip you can configure the cylinder cocks to automatically open when starting from neutral if the loco has been sitting for 25 seconds. Then after 16 exhausts or 12 smph they will shut and operate as normal. I have been configuring this on all of my QSI upgraded steam engines.
As quoted in the updated QSI manual:
Cylinder Cocks: When a steam locomotive sits idle for an extended period of time, water condenses and collects in the steam chest. Since water is not compressible and can damage the cylinder valves, the engineer must open special cocks on the steam cylinders to allow the water to be ejected as the piston moves. As the locomotive moves out, clouds of steam and water are propelled out on either side of the locomotive in such a flurry that it sometimes obscures the wheels and valve gear of the engine. Hear the sounds of Cylinder Cocks on the model as the locomotive starts out after it has been idle in Neutral for at least 25 seconds. The Cylinder$1****$2sounds are synchronized to the Chuff and shorten in duration as the loco’s speed is increased. After the locomotive has reached 12 smph or 16 Cylinder$1****$2sounds have occurred, the Cylinder$1****$2sounds will slowly terminate as the last of the water is expelled and the engineer shuts off the cylinder cocks valves.
This all is part of the QSI "Sound of Power" and although it might not sound 100% like a real steam locomotive is does sound pretty good to me. I was like you in that I did not like that a steam locomotive would start up without the sounds of the exhaust from the cylinder cocks.
To help out the Cylinder Cocks arming after Start Up and/or after 25 seconds in Neutral can be set using CV 51.2.
Just my observations. I can't wait to get my hands on a Titan.

The reasoning for the cylinder cocks is not quite correct from my understanding. Opening them prior to opening the throttle after more than a few minutes of immobility is a precaution for the sake of the cylinders, not just the valves. If the sidewalls of the cylinders hold, and the piston is strong enough to cause it, driving condensate against the end-caps will cause a hydraulic ram effect, and it will rupture the cylinder walls or eject the end-caps.
The cylinder cocks are two taps at the bottoms, and at opposite ends, of the cylinder. When they are opened in a timely manner, the first inlet of steam to whichever end of the cylinder is open for admission by virtue of valve placement above the cylinder will cause a noisy emission of steam and condensate from the floor of the cylinder. Because the cylinders are still cooler than the steam being admitted, the next minute or so of operation requires that the cocks remain open to carry out freshly condensed steam that will run down the sidewalls of the still-warming cylinders and piston faces.
The LokSound equipped and QSI equipped locomotives that I have after the initial upgrade in the summer of 2006 all have simulated whooshing or hissing. I believe the decoder is meant to count about 20 driver revolutions...I seem to recall reading that somewhere.

Crandell,
Your description of why the cylinder cocks are opened after the engine stands for a period to time is 100% correct and what you state could happen if they did not open the cylinder cocks is correct as well. I would not want to be hit by a flying cylinder end cap.
You are also correct in where the cylinder cocks are located and how they work. This is also the reason why the do not need to be opened EVERYTIME the engine starts because if it has only been sitting for short period of time there will be no condensate in the cylinders.
I have decided to get the Bachman EM-1.
But heck, thinking about it. Bachman has the tsunami sound module for $119. I'm thinking no way on that, why not get the QSI Titan for $109. ???

Michael, I have finally acquired my first Mountain, and it is the Spectrum Heavy version with Vandy tender for the C&O. I have five or six Tsunamis now, but I am finding their sounds to be as generic as those of the QSI's up to the Revolution with its newer sounds...some, anyway. So, I have ordered a Titan U from Tony. Tony is shipping a second min-oval to his customers who have to wait until his next shipment...apparently there is quite a list. The idea is that the mini is to go in the smoke box to get the chuffs 'up there'.
Worth a thought or two.

I called Tony's regarding the Titan. They come with 2 speakers, and they said the speakers should be seperated to get the stereo sound. But I think one speaker in the front side of the tender, and one in the rear end tender should be fine.
Having the speaker in the locomotive will require the speaker wiring to be used outside and into the tender.
This is for those who may miss the thread with the Bachmann forum link where the user has opened his.

This is a lot better than a few words about what is in the tender. Bachmann will be selling the 21 pin decoderr. A QSI will fit.
Wait until we hear from some trying to run this on 18 inch curves.
Speaking of the brightness of the headlight I bought the model with the small sander covers and it has the dual headlight installed and it seems to be a more normal brightness.
Meaning the brightness is normal? Or not normal?
Is the lighting LEDs?
Yes'i mean normal as in not blinding as the video showed.
And yes Bachmann is now using LEDs
This will be interesting. The motor filter, two inductors and caps are in the loco and taking the boiler off is not for the faint of heart. This may not be an issue anymore. We shall see.
WTHeck does bachmann put a capacitor across the motor terminals for? SERIOUSLY. It messes up BEMF readings because the decoder can't get a good reading on the motors true labor effort through current.
They aren't needed for Europe anymore because of the DCC decoder. *sigh*
