i think its pretty obvious that you cannot flash a DBW rom onto a DBC ECU.guys this is not going to work. You are mixing completely different hardware with completely different software.
Hint: If that was possible then accesport would work on non-US cars

05 EDM WRX is not DBW. Tea Cups, how come you didn't try the 05 ROM? From what I've seen in the ROM it's very close to what our 02-03 WRXs are. I don't think they switched hardware for the 04-05 models in Europe like they did here in the US.
The P1572 trouble code is for Subaru's immobilizer system, which didn't appear in any North American models until the MY2005 STI and Legacy GT. I doubt that DBW is a prerequisite for Subaru's immobilizer system. As far as I can tell, there are no MY2003 DBW Subarus anywhere in the world.calvinc wrote:i think its pretty obvious that you cannot flash a DBW rom onto a DBC ECU.guys this is not going to work.

Pretty much identical is not valid. It is either identical or not
Let me put it this way, 1 sensor example:
USDM ecu/USDM rom : xyz sensor referenced by software at analog input 1
EDM ecu/EDM rom : same xyz sensor referenced by rom at analog input 2
Find me a combination that will work
There's almost certainly a single instruction which decides whether to let the engine run or not by testing a flag or variable value. All you have to do is find that instruction and change it.Tea cups wrote:I'm guessing that if it is immobilizer, then there is no way around this.
