Hello, I have tuned an Audi Q7 3.0 TDI with 245hp today with an 8 gears automatic gearbox. the ecu is Aisini AL1000.
After tuning the TCU was locked. I have programmed ~ 700Nm as max Value on CAN, stock is 620Nm, when I change this Value to stock then it is all working ok, when I write 630Nm TCU is locked, so I think it has to do with limiters in the gearbox ecu.
The DTC in TCU is engine ecu software incompatible.
I will attach an virtual read from tcu, maybe someone has damos or knowledge to change the limiters or fix this dtc otherwise.
Best regards
