Fueling Parameters - ECU Master EMU User Manual

FUELING PARAMETERS

Configuration of Fuelling parameters is responsible for fuel dosing, both for the dose's size and the
fuel injection angle. The performing element in case of fuel dosage is the injector. It is the electro
valve that allows the precise dosage of the sprayed fuel. Fuel dosage is regulated by the width of
electric pulse on the winding of injector coil.
Directly to EMU we can connect high impedance (Z) injectors (>= 8 Ohm). Up to 2x Hi-Z injectors
can be connected to one Injector output. In case of Lo-Z injectors (<4 Ohm) we should apply a
current limiting resistor (4,7 Ohm 50W) for each injector or additional external Peak and Hold
controller.
Connecting Lo-Z injectors directly to EMU device can lead to the damage of the
device or injectors.
Injectors should be powered by the properly selected fuse. The fuse's value results
from the maximal current taken by the given injectors.
Injectors are controlled by switching to the ground and require the connected power grounds (G17,
G24, B24)
