Is it normal during hard acceleration (ASR Off / ESC Sport, no launch mode) for the traction control to kick in during wheel spin and the light flashes on the dash with either FWD or AWD tunes?
We can't turn off (through the ECU calibration) all of the nannies that are on the car. I can tell you that my '19 GLI, ASR Off, ESC Sport, will still do other things that will "protect" you, even when compared to my older car, a '16 GTI.
For instance, if you are ASR off, ESC Sport in both cars, and you are attempting to going around a right hand corner at WOT. The GLI just won't give you power or cuts throttle so that the car can try to go around the turn - it still tries to "achieve" whatever steering angle are are asking of the car. The GTI (PP car) on the other hand, would just roast the front tires and go straight into the curb.
There are motorsport ABS codings that will completely disable all ESP and "ice" mode, but those are too much for a car on street tires.
