I'm still confused, how is that the car's OBD is reporting exactly the correct speed, confirmed by GPS, but the speedo is reading high by 7%. And it's only since i changed these wheels..
Both digital speed and analogue speed has been set to 'accurate' via coding.
Digital speed on the dash matches OBD reported speed - both confirmed by GPS (on phone).
Analogue speedo reads high.. much higher than before..
Would the OBD speed be taking its measurements from the car's on board GPS (iDrive) by any chance?
I feel like I'm about to get a nervous tick over this....
