[redyaris]

The scan guage II in my 2007 Yaris displays Intake air temp, because I use exhaust manifold heat to heat the intake air, Coolent temperature, Throatle position switch, and LHK Liters per 100km, instintaniouse fuel consumption. The readings I use for FE are TPS and LHK. I have the option of load but never found it helpful because of my poor understanding of how to make it usefull to my driving for FE. When in cruise control on the highway if the TPS goes to 17 with a hint of engine bracking I know I can depress the clutch and coast down the hill at idle without having to tap the brake to kick it out of cruise... When I depress the clutch by mistake before the apropriat conditions prevail what the engine does is raise RPM about 600rmp then stay at that RPM for about 15sec then goes to idle, or it stays at the RPM it was at in cruise for 15seconds then returns to idle. Its interesting what our mestakes teach us...
