87 speedometer
Speedometer calibration, well now I am driving on the road, 42 miles to work, 30 on interstate, well I cruise at 80mph and the Georgia Troopers (GSP) will usually leave you alone. So had to make an Atlanta run and was moving along at speed, pulled up WAZE on my iPad to check traffic and when my speedo was reading exactly 80 mph the WAZE said I was going 87 mph! Now I had been pushing 90 on the I-285 loop (also known as the ATL 500!) so I am guessing I was close to the century mark, I am sure the GSP would have wanted to talk to me about that! So my question is can the speedometer be calibrated for my car? My 924S when I went to new wheels and tires last year I did have the speedo calibrated and it is spot on at 80 mph with my hand held GPS, but that car has a cable drive and I am guessing the 87 928 is electric.
