Hello!
I bought myself a RS6 and now i would like to increase the power.
Its my first MED17 ECU and I already have the RS7 Damos that is availiable in the WWW.
Car runs great, but I can not overcome 200% load or roughly 800nm.

From my understanding (without FR :( ) there are Driver wish maps. The desired torque gets limited by some torque limiting maps and after that it gets normalized by MDNORM and goes its way to KFMIRL.

Unfortunately it wont be that easy. so I am stuck and cant find any other values in the Damos that maked sense to increase to reach my goals. Maybe any single values or something?

Cant Attach files because they are too big =(

Get a DS1. You can do everything from map switching, 100Hz logging, flex fuel, real-time tuning, included smooth and reliable examples used on thousands of engines worldwide, all the way up to custom CAN I/O, custom maps and custom C code.

I already got vehical for logging. But also with These value availabe it does not male sense to me Why torque is limited. I only want basic stage 1. Dont think ds1 makes sense to me.

The gearbox has a torque limiter at 760nm.
Some have an additional single value at 800nm.

At the very minimum you need to flash the box and increase those.

Or you can cheat the torque calculation... which I would not recommend.

I already raised the 760nm limiter in the gearbox. I will watch out for the 800nm one Thanks!

With vcds I also logged the gearbox and there I also have the value Engine torque which only goes up to 700nm. And there is a Label called max Engine torque or something like that and that one sits at 742nm. Cant find a 742 value in my file.

D_MaxEngTorqueDTLPassive is the label. It's set to high value on some, and to random low values on others.

P.S. About 200 load, keep in mind that the cylinder-individual timing correction maps go suddenly to zero at 200 load. The last populated value is 190. That should be fixed before going over 190.
And don't go nuts on pump fuel in the middle RPM. I would not exceed 1000nm on stage 1.
1.5 bar @ 2500 rpm, 1.7 bar @ 3000 rpm is the rough boost curve for that.

Even the stock turbos have enough oomph to blow the engine up if you are careless in the midrange.

Thanks!

I finally got it. It was obvious.. 742nm Limit in gearbox like the logs said it.. So now I will try and learn :)

Post the gearbox read

Torque Limiters are @ 19BAE8 (10x1)
and @ 1E8010 (Single Value)

0x01D6824 and 0x01D695C 16x8 are full throttle max allowable torque maps

0x01D6824 and 0x01D695C 16x8 are full throttle max allowable torque maps. It also looks like you have 3 or so maximum gear torque maps too

That's not what these are.

what is ds1? where can I find it?

You really can't type DS1 into Google?

Depending on your country, "DS1" might produce other hits, but "DS1 Audi" should get you there. I'm one of the founders of Dyno Spectrum Ltd.

At the moment I am limited to 900nm internal engine Torque I think. All limiters that I know of are higher. Maybe anyone has a hint? Another limiter in Gearbox?

Thanks.

LOG:

You need to get the advanced logger and actually log stuff.
From what you posted it's not a torque limiter.

How much Boost do the Stock turbos at 100% wastegate roughly?

Enough to blow your engine up in the midrange...
At redline it's around 1.45 bar.

You can't log WGDC without advanced logger either, it does not exist in $22.

I now got the advanced logger. But I still step in the dark.
Main Problem is without right FR its hard to understand and trace down the line of errors.

Main Problem is that my RL is limited by rlmxs_w and this gets limited by plxs_w when I look into MED17.5 FR but I cant find plxs in the logger or somewhere.

There's an english FR for this engine floating around the net.

I already searched the whole net fore something like that, but I think it does not float anymore and sank like the titanic. There is only one suspicious russion website where you can buy it for 300$. But no.

I also noticed, that when I log psrxs_w which is the max desired boost its always 5200hpa. Maybe false address for that var? Because in that area must be the limitation.
rl_w  limited by rlsol rlsol limited by rlmxs and rlmxs by psrxs.

rlmxs_w is limited by:
rlmaxmd_w
rlxvd_w
rlxred_w
rlmxks_w
and PVDSRXABS - which is converted to load.

Log those.

thanks mate !

rlxvd is the most limiting one.

maybe you have an outline of the FR for that?

That's for turbo/component protection.

Max everything in BGRLXVD as a test.

That fixed the problem. No I have good boost, but the car goes into some kind of limpmode on longer WOT runs. I cant figure out why. When it happens its limited to RLMXELDR but even if I raise that map to high numbers the car still has no power then. I checked temperatures and everything seems fine on first view...

Anyone can provide good file for my car? Not for free of course.

Hi, did you resolve your problem? any news?

yes mate. running good now. Whats your exact problem? If you have that limp mode i was talking about look at KLDLUL and its axis.

Thanks for reply!
which maps exactly limiting load to 200? im trying to tune my S6 with RS6 turbos and i cant get more than 200 load, maybe im missing something?
