2012 JK speedometer recalibration
I have installed 17 inch wheels/tires on my Sport model (which was built with 16s).
According to my GPS, the speedometer is understating speed by approx 5 mph at 60.
Have found no current information on how to go about recalibrating the speedo, which also should correct the stability control process, etc.
Can anybody help this old man?
Thanks in advance.
