Makes me wonder....when a tuner remaps an ECU, is he simply changing some combination of values that could be accessed through Xentry? Such that, if we knew all the values, we could do it ourselves? Or is there more to it than that?

I think there are aspects of the ECU that can't be modified so tuners have to physically replace something like the OE ROM chip with a custom ROM chip or an EPROM chip. Thus the need to socket the ECU so you can swap between OE and modified. That's the terminology I remember from the previous century. Then there's instructions vs configurations - do you remove the command to open the EGR valve, bypass the logic that senses an EGR fault, or define EGR to function only under implausible conditions? I imagine less and less cannot be reprogrammed so you can make a wider range of modifications with Xentry to a Bluetec than an early CDI and more still than a 606. On the other hand, why can't VW just reprogram or replace TDI ECUs?

I know that a CDI can be tuned entirely through the 16-pin port (i.e it's entirely software). When my 98 was tuned, it requirement the physical replacement of two chips.

Can you disable EGR or allow 2 bar of boost in a CDI?

Yes on disabling EGR...don't know about boost limit.

I wanted to see if my menu structure was the same. Key in 2 position. I followed it all the way down to this screen (12:40 on the video):

User-defined procedures
User-defined actuations
Complete index of actuations

But when I choose User-defined actuations, I get this message:

Internal error: SGML file pkw\flexecu\flexua.s not found

And I get the same message at that point when I run the simulator.

Thoughts, anyone? I guess I'll poke my nose around the simulator some to see if I can find those actuations in another location.

Shertex,
I get the same error message with two different older versions of Xentry in developer mode on my 2006 e320 cdi. I was interested to hear that you got the same error in simulator mode... that seems to suggest that there is a file missing on the diagnostic computer side of things.
If you back out of the menu system a few clicks, there is a list of all actuations. I read through this list to see if I could find something that is close to what we are looking for - (Lastschlagdaempfung), but no luck so far.

Yeah, I'm beginning to think we've come to a dead end on this.

Shertex -

I am using Xentry/DAS 10-2011. I was able to download and copy the missing flexua.s file to F:\Programme\DAS\Trees\pkw\fleecu This at least got rid of the error message, but it does not provide the parameters that Scott shows in the video link that you provided in your original post, . Scott gives a download link for his version of the file, but that link no longer works.
Scott is showing how to modify the parameters on a W204 with the CDI6 controller. I am pretty sure that the W211 has a different controller and not all parameters have the same names. I can not read German, so the method would be to open up an online translation site and start translating the 100 or so parameters and experiment with the ones that seem appropriate.
I might be willing to work on this on some long winter night, but I actually need the car this summer - so this will have to wait.

Its not over yet! Keep in mind that Green Diesel Engineering has a firmware update and programmer for our 05-06 CDIs that will do exactly what Scott is showing. The only difference is that GDE is happy to charge plenty of $ -
So it is possible... we just need the parameters.

If you happen to have a copy of Scott's flexua.s - I would appreciate a download link. Thanks in advance!!
