If it is the same ECU as the other STi's then I might have that information saved. Let me pull out the discs.
its the same ECU, there isn't any mechanical differences between a regular sti and the limited edition
I thought the 07 ECU's were different? Not sure if the pin out is the same but according to some tuners the ECU is different. http://forums.nasioc.com/forums/showthread.php?t=1125595
so far what we've seen from the 07 WRX, It's the same ECU as the 06. can't really speak for the STI... but i do know there are some wiring differences in the car, i don't know if they extend to ecu. i think the better question is, why do you need the wiring diagrams?
I had also heard that the '07 STI ECU is different from '06 and prior. Read: http://forums.nasioc.com/forums/showthread.php?t=1125595 Though the Ltd is the same as regular STI, no diff there. (oops, duplicate link posted)
i didn't realize they made changes from the 06-07. limited 07 to regular 07 should still be the same though.
