Hi guys,

I have been searching the forum for the 2003 ADM WRX ecu pinouts but unable to find.

i have also gone through the ECU thread but most information seems to be for sti..

i want to install an apexi boots controller and want speed,rpm and TPS signals.

also, do people even use standalone boost controllers? or just let the modified ecu manage it?

please be kind on me.

thank you.
