[mosty]

Hello there,
i hope somebody can help me.

I have changed my wheels and tires from orginal:

245/40 ZR18 Front and 285/35 ZR19 Rear to

275/35 ZR18 Front and 305/30 ZR19 Rear

now i have the problem, when i drive 170 km/h and faster, my ASR goes on and i must switched it manualy off that i can drive faster.

Where can i changed this in HPtuners??????

Thanks for any help..........

The reason is because you installed taller front tires, and shorter rear tires.

I would install 265/35/18 front tires, as only BFG makes a taller rear tire (295/35/19).

Your stock front = 808 per mile. Stock rear 774 per mile. Ratio difference 4.3%
As long as your upgraded tires (front and rear) fall within a fraction of a percent of the original values, you won't have ASR issues.

Upgraded front 812 rotations per mile
Updated rear = 793 per mile...New difference 2.3%

Not sure what an 821 and a 766 would do...

I understand it, but my Question was can i change it in HPTuners????

I ask because at DiabloSport (Predator) they say you can change it....

No that won't fix it either as it is a ratio difference within the ABS module not the Engine control module.
