I drive really slow and tekan the accelerator minimal (20% at most).
GEFORCEXTREME,
Let's say we follow your example, I don't think the injector would max out. This is only a 1.8L SOHC. Not some big cc engine like 4G94 2.0L or more. Almost 40L of fuel for less than 350km mostly on highway driving (never exceed 3krpm). Even a 2L turbo can do more than that :(
If say I were to get an E-Manage or a simple SAFC, do you think it will reduce the petrol consumption or increase? Since your theory is that the car is running lean, meaning the management will only serve the purpose of adding more fuel and that will make the car's fuel consumption to increase, am I right?
You keep saying about 4G94 2.0l... in fact its not that much more higher in displacement that a 4G93 1.8l which in turn is not much higher in displacement than a 4G92 1.6l. I was just trying to answer why you experience lean afr while on the same time high fuel consumption. Btw, running lean is also a very narrow concept. Your car could run lean on high RPM and rich on low RPM... who knows? But I say a E-Manage and dyno tuning would be a good investment.
