    You can tune the factory ECU with EcuFlash.

    Are you staying N/A or are you going to turbo the car? Also, does the car still have the auto trans or have you manual swapped it?

    No problem.

    I just wanted to get an idea of the car's configuration because that will also determine if you should or need to swap the ecu.

    If you stay N/A, the factory ECU will do everything you need it to do.

    If you boost it, you'll want/need to use a 2003-2005 Eclipse GT M/T ECU, which requires re-pinning the ECU connectors. This particular ECU allows for a patched ROM file that has greater definition for load greater than 100%. The only catch is that it does not control the auto trans.
