After doing this and the usual maintenance I now get 7.6l/100km in heavy stop start highway traffic. Pretty happy with that.
I have a 33 Imola 1.4 also fuel injected, that runs the Weber Marelli system.
No dizzy, no AFM, no CO2 adjustment....nothing....1.4 engine and I never got down to 7.6l/100km cruising, so forget those numbers in stop and go traffic.
What I get is aprox 8-8.5L/100 when cruising in the highway and not pushing to hard!?!?!
