Sorry, a small question : which afr in the diesel you get more power or torque ?
In the map of my car I noticed that the rpm low c'? a ratio afr of about 13 rpm low and gradually increases up to 19 - 20.
When I am in the conditions of a afr =13 , my car does not smoke as ever ?
ES :1000 rpm, 570 mg of air and 52,2 mm3.
