As you can tell from my post count, I am brand new when it comes to RomRaider and the Subaru ECU's. So after wasting 4 hours searching and getting no where, I'm going to break the first rule of forum etiquette and ask a very newbie question

How can I find out which ECU I have? When purchased, I was told it was an ECU from a 2001 JDM STI Impreza with an EJ207 V8. Infortunately for me, whatever ECU def I download does not seem to work as I get the dreaded "ECU cannot be found" error. I was able to download from the ECU using ECUFlash but can't open it with either RR or ECUflash. I have been able to download some maps from here and can open them successfully, thus the reason for my question.
Thanks in advance
Joe
