Yann Posted June 12, 2022 Report Share Posted June 12, 2022 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. Quote Link to comment Share on other sites More sharing options...
