Brothers...
Again, my feilo is really alive now! it's a new feilo totally....
First of all, it no longer use the airflow censor no more. Which means, I don't need to replace it or think about it ever again.
The 2nd ECU basically act as a new brain, reading the engine's RPM and Throttle then sends AirFlowMeter AFM voltage to the 1st ECU.
From the Graph, you actually see the fuel that goes into the engine from 200RPM till 7000 RPM.
The graph is built from the MAP like an Excel Sheet.
My car is tuned for best FC on throttle off and Max fuel on throttle. Meaning, if i cruise, less fuel will goes into the engine (lesser then original ECU), the on throttle, I can overwrite orginal ECU by sending false AFM reading to get the 1st ECU to pump more fuel.
