Speedometer "Error" on your Latio ?
rongshu:
when the show your speed sign is ready, we can all test our speedometer's accuracy.

Same here. Speedometer reading higher than GPS. I tend to believe that GPS numbers are correct. GPS readings tend to agree with some of the radar displays that LTA has set up.
Ying:
speed of distance/time vs displacement/time
I believe the speedo meter give us speed measured from our wheels, The GPS give corrdinate only, the "speed" it gave is derived from a calculation. Using 2 coordinate divide the time taken it gives you displacement speed at most, the division it self will some some accuracy/round off problem. If one can spin the car, the speedo should have some reading but GPS give 0 kph.
like some bro said, pay more attention to the car and road than the speedo when driving. Driving under speed limit can kill if you always look at the meter but not the road.

What I meant is that we need to keep watch on our speedometer occasionally too, bearing in mind that the upgraded rim and tyre configuration will result in a faster actual speed than the speed shown on the speedometer.
And sometimes when driving downhill, you can unknowingly exceed the speed limit and get a speeding ticket.

Are you sure definitely will increase in speed if change profile in rim and tyres ?
If you are a seasoned driver, you can roughly estimate the speed even if you dun see your speedo.
