Hello all !

 i work on golf 6 R20 270hp and after good remap i have a only little gain.

i can feel hesitation du to my DSG Torque limiter.

i know it's possible to tell the DSG computer you are making less torque
I can scale/edit the torque values ( factor ) to appear lower in the med9 ecu.

do you know wath function or factor i need mod for that ?

sorry for my english !

Thank's in advance

Change torque limit in DSG. All other solutions is just not correct...

CDLF should have about 350NM from factory and in these cars DSG is limited to 380NM. You can also see torque limitation in measured blocks, should be 122.4

Don´t claim something if you didnt check it...
There are few versions with more than 350NM allowed. In attach a DQ250 file from Golf R and other DQ250 file from Passat TDI. I think you will find the offsets yourself. Btw ori shift rpm should be 6700...

I still think it´s not a good idea to cheat torque and let the tcu calculate with 100NM less, maybe think about clutch slip regulation and wear. Change tcu torque limit is 5min job.

You should check yourself. That 380 is max torque is an upper protection tripwire mmr_MMaxGetriebeschutz_ko.

MmrTemperaMmax_kl caps TQ at 350 up until 138deg C then the TQ limit drops to 15Nm.

Attached Passat CFGB is 380NM from factory, can you explain this? ;-) In my opinion this map is active from 138° only, not before. But i dont have FR for it.

Only, if your stage1 has NOT more 340Nm indicated.

that´s correct:
ECU will limit all communicated torque to 340Nm.

Problem on this:
MO1 and M06 torque is indicated, so flywheeltroque is mutch less then 340Nm

All torque higher than 340Nm indicated are cutted and all feed forward torques are worng.

As well as all adapted torque-to-pressure values ...

Only mirco-slip-controler will learn, but has mutch trouble, if differend learn value for same communicated torque higher then 340Nm indicated.

So even on stage1 tuning this way is a VERY BAD idea !


to keep it short:
all ideas, NOT to tell actual torque correctly to DCTs is CRAP.

Depending on actual situation and amound of troque you are running.
On launch and high speed gradients, you will get in trouble, if the actual torque differs less the 10Nm to communicated torqure, even if the inertia of the engine is low.


Yes, if you are in status "fahren" and the micro-slip-control adapt to mirco-slip-speed-limit and press "correct" to actual troque.
So it will work in this special condition. But you will see, micro-slipp-controller needs some time to reduce slipping.
All controled situations will get in trouble, if the communcated torque is incorrect. So off-going clutch during torque-hand-over e.g. or most importanted: launches poweron-downshifts.

Cannot match to this !
Take a look at clutch slip of the shafts and calculate the energie you loose by slip, you will see how mutch stress you will put into the system, when you running at torques higher MDNORM indicated.

Running alltime short-hard shifts and fast launches, you will not sense the shocks, you will get by incorrect troque, because the kind of application shocks by physiks.

But if you want to have a smoose and findly clutch control even on high torque, you need to tell correct torque to DCT.

And this will not happend, if you cut the high torque communicated on you "stage1" tuning.

The point is:
as long as you are running lower the MDNORM indicated, the DCT will work with proper communicted torque and work well.
This will be the cause of most times running a stage1 tuning.

But racing or mutch time running above MDNORM, will have bad impact to livetime of clutches and DCTs
