Calibration
Battery voltage
ColorMFA measures the battery voltage (vehicle's on-board power
network) for display on the screen. If the voltage measured with an ex-
ternal measuring device (DMM) does not match the ColorMFA readings, it
is possible to adjust it by entering the difference in the measured value
and the current ColorMFA reading.
Speed Source
In some cars with ASR / ESP installed, it is possible to select that
speed source for display on the ColorMFA screen. In most cars, velocity is
measured by 2 methods: the sensor in the gearbox (connected to the
dashboard) and the sensors in the wheel hubs (connected to the ABS /
ASR / ESP block). If the car is equipped with an ASR or ESP system, it is
possible to select the speed source to most accurately display the real
speed of the car. In vehicles without ASR / ESP, there is no such choice
and only the speed of the instrument panel calculated by the sensor in
the gearbox is used.
When selecting a speed source, keep in mind that other units in
the car can use a different source than the chosen source in ColorMFA.
This can lead to the display of the preset cruise speed and the current
speed on the screen to be mismatched by 5-10 km/h.
