EcuFlash — Read/Edit/Reflash Subaru & Mitsubishi ECUs via OpenPort 2.0​#

Read, edit and reflash Subaru & Mitsubishi ECUs with OpenPort 2.0, smart ROM definitions and J2534

EcuFlash is a Windows application used to read, edit, and reprogram engine control units (ECUs),
most commonly Subaru and Mitsubishi. With a Tactrix OpenPort 2.0 (J2534) and the correct ROM
definitions, you can open stock ROMs, apply calibrated changes, and reflash securely. The UI is clean:
a left panel for Open ROM Documents, a middle metadata panel, and a live Task Info log that
shows libraries, checksum modules, and protocol loaders in real time.
