If anyone has a Tuned and\or Deleted CNRB and VCDS, I'd be interested in seeing some values from a log.
Let me know if you want to share, and I can help guide you on how to log what I'm after.

These are the MVBs I'm looking for
IDE00021 - Engine RPM
IDE00190 - Charge air pressure: specified value
IDE00191 - Charge air pressure: actual value
IDE00348 - Intake air temperature
IDE00361 - Ambient air pressure
IDE02229 - Exhaust gas temperature sensor 1
IDE04677 - Oxygen sensor 1 bank 1: lambda actual value
ENG106231 - Ambient temperature

And it would require a 10min drive or so, where you have the opportunity to bring the vehicle up to full operating temp and where you get the chance to wind out the RPM by flooring it and keeping it pinned through a few gears.

Happy to give that a go this weekend if time permits. Would be happy to hear your assessment.

I'll share anything I learn.... right now, I only have my stock data so can't really compare against anything until I get at least one more data set from someone who wants to play along.
I'll be after the log csv which you can email me or share though whatever service you want....

But don't get all excited... I might come back with nothing IF my theories are junk!

 

[ValveCoverGasket]

is this going to turn into the EGT hand wringing thread?
since it looks like youre reverse engineering tunes... maybe want to throw in some injection timing parameters in there too.


probably want full load sampling in a couple of higher gears so you get good time in gear for the requested/actual boost to settle somewhat, and for the load to sit.
maybe even sport mode to lock in a higher gear, so it can sit a bit longer and run out, id suggest WOT from as low of an rpm as you can manage to grab


but thats just like, my opinion, man

 

[SaVAGeSoot]

Oh no.... I'm after Lambda now too.... not just the infamous EGTeeeezzz.... you'll love it... so subscribe

without knowing exactly what youre after, thats a really slow sample rate. does it pick up a bit when you pull some channels out?

 

[SaVAGeSoot]

VCDS is a very capable tool for what it is and what it costs.
This isn't F1 Telemetry, so I'm not worried about sample rates at this time.....
But if you really want to be a trend setter, then you can tweak your sampling rate by using the turbo function and only one MVB at a time..... and even some VCDS setup values I think....

Let's start with basics and if people want to play, we can get to that point where we optimize stuff..... if I'm completely on crack, this poor sampling rate should be sufficient to shut me up.

 

[ValveCoverGasket]

for what its worth, i do quite a bit of remote tuning (on gas cars), and to really see much of anything useful - again im not totally sure what youre after here - you need to be somewhere in the 20-50ms sampling.

i guess seeing that its so slow, ill re-emphasize my prior point about needing to take all your WOT pulls in the tallest gear you have room/comfort for.

This isn't F1 Telemetry, so I'm not worried about sample rates at this time.....

~1hz sampling is like a telegraph so yeah, nowhere in the same century as F1, or even decent standalone from the early 2000s

on my tdi swapped vanagon ive taken some 1-3 channel logs with VCDS but its running an old slow 68pin ecu. my assumption was that the limitation was the protocol on those ancient boxes but i guess maybe its VCDS also after seeing your touareg log.

 

[SaVAGeSoot]

I'm not tuning anything.
Slow sample rate is still better and faster than no data at all in my view.
I'm trying to confirm my theory that these canned tunes run way too rich and this is why tuners also raise their EGT limits, while also working the turbo too hard..... And making IATs undesirable.

To get to a tuning point, we'd need much better logging equipment and even sensors.

As far as sampling rate ability of VCDS, I've read the specs somewhere, but they were nothing worth remembering.

Baby steps.

See if I can grab some logs when I'm home on days off. No promises though, four days goes by fast. Interested in seeing what you come up with though, so I'll see if I can.

@ValveCoverGasket
As mentioned, I am aware of the limitations that "we" are working with here.... but it's just a "generic" evaluation, not really a tuning attempt. Visual that I'm not sure saying stuff....

You already know all this son... you've worked with all the tuners and have explore all the Touareg's limits before jumping on the SQ bandwagon!

Spoiler alert:
I won't like the EGTeeezzz or Lambda values that will come out of these canned tunes!
(so grab a coffee and get ready for some arguments)
