    ECU Features

    Note that these are all the current features covered by the mercury2. There are some on the charts that is in the process to be developed in the future. The hardware has the capability for it. Also note that not all of the features may be included on the same ECU as there is limited amount of drivers available. Some of the hardware classes may not include certain features due to the price range. See the selection chart for the ability of the different classes.

    Fuel Delivery

    • Accurate fueling such as batch, Split Batch, Split Sequential, and Full Sequential gives better performance and fuel consumption due to constant atomization on each cylinder.
    •  
    • Fueling is done in graph or matrix method for the tuners preference.
    •  
    • All graphs or matrix data are interpolated to smooth fuel calculation accuracy for best performance though the operating ranges.
    •  
    • Fuel is calculated with MAP sensor or TPS versus RPM signals or a combination of the 2. This will accommodate most engines ranging from street to racing and from economy to performance.
    •  
    • Other sensors that are used to alter the fuel mixture are Water, Air, Altitude, Lambda, Battery Volts, Fuel Pressure and throttle response.
    •  
    • Fuel injection timing is adjustable on gear type crank angle sensors as low as 12 pulses per revolution.
    •  
    • Adjustable MAP sensor reading angle for multiple throttle body systems.
    •  
    • Two types of micro fuel injection methods (staged injectors) namely Ratio adjust or Graph Fazed method.
    •  
    • Fuel pressure control with pressure compensation maps.
    •  
    • Injector trimming up to 8 injectors.
