Hello,guys i have just registered to ask something about my car Skoda fabia /1.9 SDI 64HP engine 2000 year/. Now the question is- What is better injection quantity for my pump and fuel saving? Factory setting is 3-5 mg/stroke.I had 1.6 mg and the car was so good i needed to use throttle less than 4.0 mg/ it is factory setting.The problem was vibrations and incorrect fueling.And second question is constantly i drive with 1000-1200rpm and 1700rpm without load where i shift higher speed.Is it good end fuel efficiency to shift around 1700 rpm or higher rpms.I thought that lower rpms are economically but i am not sure,board computer shows bigger values of fuel at lower rpms.Is it true.Also which way to use fast acceleration between 1700 -1000 rpm or slowly acceleration, sorry for my bad english .Thank you in advance.Best regards from Bulgaria
