h82lose91 Posted August 29, 2020 Report Share Posted August 29, 2020 Swapping a complete setup (Engine, Turbo, Fuel System, etc) from a 2006 STi into a 2001 2.5rs with 2004 STi Harness and ecu. The RS ran and drove fine with the 2004 OEM STi ecu and Harness. Oem ECU powers up and is working. Is there something else in the LINK that needs to be configured besides changing the two jumpers from Horizontal to verticle? I get a no start and no pclink communication.

Adamw Posted August 29, 2020 Report Share Posted August 29, 2020 Assuming you have the WRX104 ecu, then it is likely just the jumpers. These swap what pin the ignition switch signal is received from and which pin controls the main relay. Quote Link to comment Share on other sites More sharing options...
