Please, SOS. I am searching for an expert/ wealth of knowledge on the Subaru tuning, particularly the 2003 Subaru Legacy GT factory EJ251 with 5MT. I have been scouring left and right across yee old inter-web, and have tried several approaches to no avail....
so back story I bought this car on a deal about a year ago, had big plans... made the mistake?? of buying a replacement EJ251 (original engine was yanked and sold, as last owner grenaded the trans) then began the quest of literally replacing everything on the car... from the engine to the trans, wheel bearings, brakes, driveshafts, CVs, the whole 9 yards.....
I built the motor slightly, some simple add-ons, bigger injectors, fuel pump, TD05-G turbo kit. I re-did the head gaskets, added head shims to lower compression for the turbski add-on, replaced water pump, timing belt, idlers the works. **no internals, heads, or block changes***** had to replace the oil pan due to damage and the k member to accept the turbski…
so in search for tuning support.... I reached out to Cobb, red line, ect. every major tuning / support company in the country, and no one supported the 03 ecm… why? I'm not sure. they all support 04-05, but not 03.
began to dig into open source tuning, bought a tactrix cable. ECUFlash and RomRaider deluxe. ECUFlash doesn't support it either. RomRaider support forums list an 03 JDM Ecu as a 16 bit ECU, which they do support. Keyword, JDM. not USDM...…
Has anyone, please.... lol found and interface capable of communicating with these ECUs?
