speed in car's OBD-II computer vs. speedometer
Confirmed in the SR automatic I'm driving that the speedometer is consistently reading 4 km/h higher than the car's computer, which looks to me like a correction factor. I used an OBD-II scan tool (ScanGauge-e) and checked from 30-100 km/h:
Speedometer reports...
|
OBD-II value... |
30 |
26 |
40 |
36 |
50 |
46 |
60 |
56 |
70 |
66 |
80 |
76 |
90 |
86 |
100 |
96 |
I didn't check against the odometer, but will do that too. I bet the dash display matches the OBD-II values.
