Jorge Ortiz Posted May 12, 2022 Report Share Posted May 12, 2022 Hi! After installing the G4X on a 2006 STI the boost selenoid is not working. What we do so far: 1- We test the solenoid on the bench and is actuating good. 2-Check continuity on the car harness to the ECU and is good. 3-With ignition on no matter what we do on the software we have 12.5 volts on both wires coming from the ECU. 4-We check for what auxiliary out is the one to use and we have the correct Aux 5 output. 5-We check for the jumpers on the ecu board and it has the correct ones 2005/2006 Hope Somebody can help on this situation.
