Hello,
i take a "Muscheldiagramm" (i had no word for it) to find out when i shift.
A normal gasoline Engine has a diagram like that:

The best motor efficienty are between 2000 and 4000 rmp about 80% of the maximium torque. The motor mangagement system of my old car use a fully load injection in these areas -> bad efficienty
So i take them out (blocked the throttle flap to max. 72°) and is all good.
accelerate in these areas and you safe fuel
My car: Volkswagen Polo 2F (builded 1990!) with 55HP Monoinjection engiene and bad cw (0,36) takes 4,4l/100km (53mpg). evaluated over 20000km.
