question about flashing a JDM ecu

[Rei_Akira]

i have talked to a few people, and they're not sure if its possible to perform an open source tune on a JDM V4 STI ecu, does anyone know (personally i know know much about tuning). any help would be appreciated as it will determine the plans for my vehicles build.
