Im no expert on emanage, but having installed the blue by myself on my 4g13, heres my 2c. What do you think?Feel free to add to discuss.
Theres a trick.to use emanage in0v need its full harness.ignition n fuel. Sensor will, as usual provide feedback in voltage to the ecu.then the ecu will churn out the instruction.Emanage then will take over this signal.emanage then churn out its 'own' instruction to the ijector n such.Meaning to say that emanage will have the last say.Ecu already did his duty.Even though the ecu will keep modfied its instruction to injector,emanage will still calculate his own instruction,no matter how. EMANAGEĮmanage on the other hand.is quite different. Safc mode of operation is to sit between the sensor and the ecu.This mean safc manipulate the sensor will lower down or increase the voltage to give a modified signal to ecu.Then the ecu will do the nececassry 'thinking' and give the instruction to injector and other stuff to run the engine.
Normal efi operation is.sensor send signal to ecu.ecu will do the math and send signal to injector,solenoid etc to run the engine.
