That's a great find. Since it's called Rough Road/Engine Torque signal, that gives us a better idea of what the setting affects. Lends some credibility to the theory that the system uses the ABS sensors to detect and monitor wheelspin. I'd bed that it compares the rotation rate of the front and rear wheels to determine if the front's are spinning faster than the rears and interprets that as wheelspin, then acts accordingly.Found this - certainly seems plausible in terms of whatever the "rough road" system is w/r to the brake system and it's impact on limiting engine torque.

The only risk that I'm aware of is for wheel hop to occur. The chance of it happening on dry roads is minimal, but it can definitely happen on wet roads, especially on modified cars with greater than stock power levels. As long as the driver understands what wheel hop is and knows how to counter it, they should be fine.honestly... you don't need to go back and forth. if you own one of these cars you know how disappointing they are from a dig. i was really considering taking a loss on the car. the difference is night and day. similar results to pulling the abs fuse without the bullshit and losing functionality.
i don't know how or why. def need more information on exactly what is happening and whether this is safe long term. i reached out to another gti owner. he said it didn't help and he seems to know really know these cars...
sorry for my ramblings... i need coffee. very happy with how the car is behaving currently.
I did some more testing last night. Turned the setting back on, then did some aggressive acceleration from a stop and a slow roll. As soon as wheelspin occurred, the power was reduced. I turned the setting back off, then did the same types of aggressive acceleration on the same section of road and didn't get any power cuts. The wheels spun freely and I could control it with the accelerator.
