I have the same car (2007 Subaru Forest 2.5X AT) and the same problem.

Unknown rom in ECUFlash, and no definitions in RomRaider.

None of the "2007 Forester" definitions in the various forums flagging this problem work. Please help!

I finally got it to work! I was able to identify the ECU ID in ECUFlash when it ran connected to my car computer (in the main window where it shows status / what's happening). I then did a search for the ECU ID, and came across a forum with definitions I thought I'd already tried. Nonetheless, downloaded again, followed the instructions (including made sure I had the 32 bit base file in the directory)....and it works!!!!

Good luck! Post here if it works for you.
