Audi Speedomiter Calibration

[v6thomas]

Hi Gents,

Recently upped my wheel size from 19 to 20 inch but wanted to keep the same profile on the tires to fill my arches and keep comfort (35).
The speedo Is reading higher speeds as obviously my wheel gained an inch.

Does anyone know how to code it to allow for the bigger wheels?

I found in Instruments, Byte3 there's this 00 Tire Circumference option but there are no other options in the drop-down, Dose anyone knows more about this? Can I tell the car its got A7 wheels? or something
