I also don't know what the intended function of the "triphase module" is, but if it's a typical inexpensive bolt on that is supposed to enhance performance by changing the MAF signal to lean out the AF mix... it's not going to work. a 98 vehicle is OBD-II, and any tweak to the maf signal will quickly be corrected out in the block learn tables... if it's a big enough change it'll throw a code.
NOW... if this doohickey also intercepts the O2 sensors... well then it may be worth something, but I've yet to see a bolt-on that can scale O2 sensor input. (although I don't know what's out there for subaru's)
