OK, so my inner OCD is bugging me.
My speedo reads about 10% high. I am doing a GPS 45 and the car reads 50mph or thereabouts. I don't mind this except that all the speed camera warnings are based off the car reading and not a GPS reading. So I am doing actual 48 in a 50 and the car is bleeping at me.
So - how can I change the in car speed to read a more accurate number?
I went to Kia today and was told the reading comes from the ABS sensors, into the ABS ECU and from there to the cluster but that they have no mechanism to recalibrate the speedo.
Any ideas?
