PVDNV is for idle control when vehicle is moving as I understand it.

I did not delve into it too much - I just saw the map, and thought I'd try it before anything else. Upped it some and the problem was gone...

The oscillations in my log looked like a PID controller with too low P and it seems I was right.

That's a good question. Unfortunately I am not a long distance mind reader, and don't have any clue which binary you are using Wink

I'm going to need to do this in my S4.  I have a very light twin plate clutch and I've had a few stalls while coming to a stop and declutched.

PVDNV?  That's my next step as it seems logical.  I've already bumped up the torque reserve as you mentioned as well.

Hey prj, do you remember where the address is for PVDNV?

Is 0x11221 and factor -0.000000+X*0.001526 correct for the M-box for PVDNV?  I'm interested in playing with this map as well to correct a stumble at idle when the car is rolling at 1-2 mph and the clutch isn't pressed in.

Prj, would it be likely that these things would involved when there are problems with stalling in cold weather with thick gearbox oil in addition to idle torque reserve?

You mean with the clutch in ?
I just changed P because I had P oscillation.

Does not mean this will solve all the problems in the world.
If you have stalling when cold try tweaking KFMRESTA a little bit and see if it makes it better.

KFMRESKH is a nice map for it, but unfortunately only used when cat heating is on.
However, it is possible to hack the ECU to run always from KFMRESKH.

I found this in an audu tt 225 ols with a pretty extensive definition list:
Characteristic P-gain at start (10x1)

U / min
-100.000 -50.000 -10.000 10.000 50.000 100.000 150.000 200.000 250.000 300.000

but it's PVDNST
