I posted this earlier today to the S4 forum and was wondering if any of you A4 guys with non-stock wheel rolling diameters did to get your speedometers calibrated properly. I'm guessing its a setting somewhere in the ECU or Instrument Cluster... any help would be greatly appreciated!

Well I was wondering if anyone had any info on how to get the Speedometer calibrated on my S4? I want to install 235/40 17 AVS but I don't want to deal with the speed and therefore milage running faster. I know it may not be that significant but I'm a little ****. Any clues would help. I would imagine its a setting in the ECU or maybe even the instrument cluster but some definitve info would be appreciated.<ul><li><a href="https://www.audiworld.com/forum/m/s4/msgs/206268.phtml">Link to the message and discussion in the S4 forum</a></li></ul>
