  1. Hi,

    I tried the first start of the engine after an injector and ECU change (top feed conversion, and ECU changed for a G4X) but I don't have any fuel distributed.

    the setup is : 
    Fuel pump 255l/h Walbro

    Injectors Siemens Dekka IV 80lb (840cc) ; 12.5 Ohms

    I created a gauge with the injector duty cycle as below

    While cranking the max reached by the gauge is 0.8 %

    I tested the injectors out of the manifold and they are not cycling meaning I don't have nay fuel coming to the engine. I didn't measure the impedance at the injector but they are supposed to be high impedance.

    The deadtimes are coming from the manufacturer's chart so I guess they are OK.

    I didn't fill the "short pulse width adder" table.

    Here is the base map I am using to start the engine: 

    Subaru WRX V5-6 Premier demarrage.pclx

     

    Do you have any clue where the issue may come from ? It's like for some reason it refuses to send signal

    Thank you in advance,

    Best regards,
    Yann.
