Okay, I understand that. But then, in the 6HP19A must be a hardcoded limit, if Max Moment am Can is changed to values below 630 Nm the norm value read with vcds in the gearbox is the same as set in Max Moment am Can. All values above that result in a norm value of 630Nm and also actual engine torque values are lower than that. (in ecu I can read inner torque of 750 Nm)
Max Moment am can below 630Nm result in perfect partial load shifting behavior.

Would here help a scaling factor like Faktor für Ausgabe Motormomente am CAN (Com_facTrq_C) to get for example 2*630 in TCU?


 I think Maximales Moment am CAN (Normierwert MDI) (Com_trqMaxNorm_C) is the same as MDNORM and what you mean is Multiplexinfo (Com_trqENG5MuxInfo0_C). As I said I'm talking about EDC.

Thanks, I thought about something like this. So there is no solution to get more torque than 630 Nm into the tcu.

But which value has MO2_max_Mo? Is it the factor 10 on the 6bit value?

In tcu I have the map: Skalierungsfaktor für normiertes Motormoment. The value is 10. In RS6 TCU file this factor is set to 20. but changing the value to 20 changes nothing to the norm moment in my case from what I see in VCDS, it stays at 630. Never tested it while driving.

witch  Vehicle, witch CAN-Bus-Version ?
The limit is CAN version based. It can differ between plattform or versions.
PQ-based CAN-Bus got the limit of 630Nm in all versions (upto V566)

V8 and V6 are not PQ. They are PL but Audi A6 C6 (V241) is also limited to 630Nm on CAN.
Never take a look to RS6, but e.g. R10-Touareg should also use 1000Nm. Both are not PQ-based and may use there own DBC-Version, like the Bugatties too
MO2_max_Mo is a 6bit value, see attachmend. Bit 7 and 8 is used for multiplexer-value.
On PQ-based CAN, the scaling factor is 10, so no chance to send more the 630Nm without chancing the factor.

It is possible to recale MO2_max_MO.
If you do on ECU, you chance  the CAN Interface, witch is fix in DBC based on defintion.
If you chance this defintion, you need to chance the scaling on every controler, with reads this value from CAN.
Scaling factor is not communicated on CAN, so no "autoadjust", when you chance it in ECU application.

No, RSQ3 is MQB based, not PQ.
MQB can change MO_Faktor_Momente_02 in ECU and it will be send on CAN, so easy to change the limit for torque on CAN.

Yep, agreed. Maybe it's MQB "based" but the whole car is PQ and VERY similar to 8P RS3 if it wasn't for the lack of MED9 ECU.

Hello Piar,

In which mode do you want to modify ? Drive ? Sport ?

Drive : SHALT tabele 3d maps 14*21 at adress 24250

Sport : SHALT tabele 3d maps 14*21 at adress 2440C

Damn, so I suppose one of the 2d maps IS a limiter. Don't know which one, but if you know the currently speed for upshift, you can search and try, difficult without the FR.
