In legatura cu anumite chestii se pare ca m-am inselat. Cand se intampla asta recunosc Se pare ca viteza e limitata electronic la cat e specificat in carte. Am studiat la modelele de M3, M4 catalogul si ele au limitat electronic la 250km/h. Atasez catalogul, la pagina 25 se poate vedea tabelul. Limitatorul se poate scoate cred, e din soft. Atunci poate merge mai mult. Pe raspunderea ta. La vitezometru exista o eroare intre viteza reala si cea indicata. Citez din wikipedia: Most speedometers have tolerances of some ±10%, mainly due to variations in tire diameter.Sources of error due to tire diameter variations are wear, temperature, pressure, vehicle load, and nominal tire size.Vehicle manufacturers usually calibrate speedometers to read high by an amount equal to the average error, to ensure that their speedometers never indicate a lower speed than the actual speed of the vehicle, to ensure they are not liable for drivers violating speed limits. ---------------------------------------- International agreements EU: European Union member states must also grant type approval to vehicles meeting similar EU standards. The ones covering speedometers[7][8][9] are similar to the UNECE regulation in that they specify that: The indicated speed must never be less than the actual speed, i.e. it should not be possible to inadvertently speed because of an incorrect speedometer reading. The indicated speed must not be more than 110 percent of the true speed plus 4 km/h at specified test speeds. For example, at 80 km/h, the indicated speed must be no more than 92 km/h. The standards specify both the limits on accuracy and many of the details of how it should be measured during the approvals process, for example that the test measurements should be made (for most vehicles) at 40, 80 and 120 km/h, and at a particular ambient temperature. There are slight differences between the different standards, for example in the minimum accuracy of the equipment measuring the true speed of the vehicle. Sper sa fie de folos.
