IIRC, Enginuity and RomRaider are the exact same thing... they just changed the name. And it's just a map editor that uses OpenECU (which is just an ECU I/O library, not an editor) for reading/writing to the ECU. But that said, I don't think there's any other software out there to try. You just need to be absolutely sure you've got the correct ECU definition for your ECU in the OpenECU program or you could kill the ECU.

The ECU definition tells the software where the different tables are stored in the ECU's memory. If you've got the wrong definition and read the maps, you're going to get a ton of nonsense when you go to look at it in RomRaider. Worse yet, if you write with the wrong ECU definition, I but you could permanently jack up the ECU if the hardware is different enough from the ECU you think you're writing to.

How do you know you've got an EDM ECU? Do you know the history of the ECU? It's it plausible that you got one from Europe? I'd be more likely to believe you have a newer USDM ECU or something incompatible w/ the 16-bit 03WRX ECU rather than something EDM, unless you know that's where it came from. Unfortunately, I don't know the best way to figure out what's what... but I thought the S/N on the ECU would be able to tell you accurately.

Anyway, if worst comes to worst, I've got the original '02 WRX ECU out of my car just sitting on a shelf. It's got an ECUTek license installed on it, but I'm guessing that's easily overwriteable by RomRaider. If you decide you need an ECU, feel free to PM me an offer. I was asking $200 for it, but I'd take less if you're in dire need.
