The unique H-project ECO Chip economizer is wired up to the HO2 sensor. It warrants dramatic reduction of consumption by up to 15 % in traffic jams and on highways without any power loss in regards to the engine horsepower.
The unit is actually maximalizing the Air Fuel Ratio (AFR) (fuel poor status) in those situations when oxygen sensor is sensing idle speed, engine running with small or medium load while driving is continuous without extreme accelerations.
When throttling suddenly and acceleration is essential, the unit will return to factory mode without any delay, accordingly the engine becomes active as always and oxygen sensor will deliver the normal signals to the ECU until the acceleration is going on.
