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  |

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

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 |

You really can't type DS1 into Google? |
