Anyone else checked to see at which speeds their engine cuts fuel off completely when coasting in gear? My '07 Aveo5 SVM will only switch to full fuel cut-off (indicated by going open-loop on the ScanGauge II) if the coast starts at above 40 mph (any gear), and lasts until the engine gets down to around 1200 RPM or so. If I let off the gas in gear below 40 mph it'll continue to supply some fuel, reducing the amount of engine braking.
