Injector pulse wiring

[Duduglanza]

Hi ,

As you all know the 4efte ecu has only 2 output channels for the injector pulses. 1&3 and 2&4. 

May I ask where is the part where the 2 wires split into 4? i need to fit two resistors on them for my low impedance injectors. 

Thanks

i'd suggest you drop Stu a PM...he's very knowledgeable about that kind of stuff

Convention is to fit ballast resistors to the power side of the circuit, not the injector drive side.  It will work both ways but all the literature ive seen says to fit them to the 12v feed. Im assuming you will be using something like a 25w 4R7 resistor for each injector, so find intercept the main power feed and then split it via a ballast resistor to each injector. ie 12v feed > split into 4 > ballast resistor each > injector.

Are you attempting to fit larger injectors to a factory ecu?
