according to you, ? normal for there to be a difference of 10 km/h between the speed? that marks the instrument and the real (measured with gps)??
The strange thing ? for the latter ? in perfect soncronia with that measured by the control unit with the ELM 327 and multiecuscan.
Therefore, it follows that ? the instrument that marks a speed? more (this helps to prevent the camera!!!!!)...
It is possible to align the instrument with the ECU?
have mapped the tacho!!!game. normal ec this gap, the speed is perfect and is one that measures the nav ;the gap between the ecu and the nav almost 80% of the cars are like this!!!

the thing that makes me happy... I knew that the speedometer had a margin of error, but I didn't think it was normal that a deviation of 10 Km!!!
Obviously, my 156 is part of that 20% of cars that mark the right speed? compared to the tomtom.
However, as I understand, I have to keep it cos?????
I can guarantee that on all the fiat there are 7km of displacement between the gps and tacho!"!!

Quoto! All cars fiat group that I had the opportunity to verify the accuracy of a 7kmh!!Originally Written by carlo abarth
according to me the navigator is not ? precise speed?, why? makes the triangulation of 3 or more? satellites, on the basis of the position of the satellites can? vary the average speed?, or if a navigation, smartphone as well as the satellites also takes into account the signal of the network.
I say there? why? I have studied for years the topography of the satellite and the apparecchietti that we have of a few hundred euros on make an approximation of no small account.
you, sar? definitely true what you say, but the deviation ? almost zero between the speed? detected by the GPS device and the one detected by the control unit, instead, c'? a wide margin with the tool.
I do not want if I tell a bestialit?:
You could pull the needle and reinsert it after it is made to rotate by a few degrees????
Certain that you can? do
on the contrary, if you take a reference of the cantilever,
on the deck or on the crick ports to speed? constant and then return the hand to the right place.
I don't know if I explained it well?..
be careful in extracting the needle.the moterini are delicate,I usually apply the force in the extraction and tour of senzo counter-clockwise,so that the axis f? the pin in the switch.
currency that if you move the hand you're hand moved even when the instrumentation ? off,you may find the condition in which the hand of the speed? compared to that of the free spins are not simmatrici in short, a pi? at the top compared to the other(machine turned off).
You have to take into consideration the power consumption and the size of the tires. At low speed? as a percentage ? a little, but if you go on the highway of course, the deviation increases...
For one thing, with my car, and always the same nav simply by mounting new tires instead of the smooth, the deviation ranged 3/4 km / h on the highway, let alone if you had wheels with a size of radius more, what not to imprtobabile given that the drive current are prepared for the assembly of many of the measures of the wheels.
