Update. I have soldered 0.1uF capacitor between ground pin and VSS pin and speed seems to be really accurate and does not jump around at all. after calibration/correction it is off 0.1km in distance of 102km...not bad.
Still needs some more test drives, if accuracy stays like this but as I said - instant speed does not jump around anymore.
