the map mod alters fuel delievery per boost and regulates the map signal the ecu sees to prevent err codes . the vafc allows the fueling maps to be altered by adding or removing fuel relative to rpms and other variables . the main weakness i can see with the vafc is it doesnt read boost and therefore wont effectively control tip in detanation .

I am confused I think. Will the APexi V-AFC offer everything that the JR map mod will? If not what is the difference?
