2003 A4 3.0 Speed limiting in ECU

somebody · 2005-04-11T17:52:39+00:00

Please don't chastise me. But in the name of science I took my A4 outon an empty highway near me yesterday. After some test runs up anddown this road to nowhere, looking for speed traps. I tested to seeif it was indeed programmed not to exceed 130MPH. At 135MPH I felt myquestion had been answered. At that point I asked myself, "What are Yrated tires good till?" At that point I let of the gas and two milelater I was back down to 75MPH, it felt like it could have gone faser,and the car felt great.

It should be vice versa, no? At least here in Europe that is. The speedo shows a higher speed than the actual one.

In the uk speedos always read a higher amount than the actual amount.

That is,

Speedo speed = 30mph, Actual Speed = 27mph.

I actually like this 'feature', as I tend to drive around about 10 mph higher than the posted speed limits, which generally the police will let you have - so in the case of the Audi, an indicated 10 mph over is really more like 7 mph over, which is better for the driver's license....

I have checked the speedo in both my A4 (2002) and Passat (1995) by timing the interval between mile markers on the highway at a constant speed (65mph). Both were within 1mph of the calculated result.
