DAVID / 2004 SUBARU STI / LINK ECU
A classic STI.
Built for flex fuel.
David’s blue 2004 STI combines a built EJ engine, a Dom 1.5 turbo and Link management. Explore the original AWD footage and the separate 93-octane and E75 dyno records behind the build.
ENGINE / TURBO / MANAGEMENT
The hardware and calibration belong together.
AWD’s build video identifies an IAG 750 long block, a Dom 1.5 turbo, ID1050 injectors and Link G4 management. The complete setup is reviewed around the engine, fuel system and intended use.
My calibration work brings the combination together around the fuel system, available measurements and intended use. For your own EJ project, include an external wideband controller and its logging connection in the setup review, along with the ethanol-sensing and fuel-system details.
