Wait, so you're saying that you flashed a complete 05 EDM WRX ROM onto your 03 USDM ECU and it worked without any problems? If so that's for fugging cool. That pretty much give you all the control they have. Damn, I want to bust out my spare 04 ECU and try it now real bad. I wonder if it worked fine (or seemed to) because the layout seems to be the same for some of the tables in the 02-03 USDM WRXs as they are in the newer EDM ones. If this works like you said then that pretty much solves out problem of not having "gear dependant" boost control in the USDM ROMs. BTW, the CL/OL fueling is not an issue on the 05 EDM ROM I downloaded from this site. It was pretty much identical to the 02 WRX ROM I have compared it to. This is good news so far. Someone try it on an 04 ECU... common... do it. I don't want to fry mine...
