munkyenima Posted October 13, 2003 Share Posted October 13, 2003 I have a 1998 Legacy 2.5gt and I am trying to install the next level performance tri-phase module. Long story short, i need to know which of the 3 wires coming out of the Mass Air-Flow Sensor is the MAF signal wire. There is pink wire, a white wire, and a yellow wire with a blue stripe. Any help would be greatly appreciated! Quote Link to comment Share on other sites More sharing options...
Dave K Posted October 14, 2003 Share Posted October 14, 2003 If you're doing internal work on any car it's just about imperatave to get a good manual. I have not modified either of my Soobs so I don't know what to recommend... but I'm sure you can ask around and get some imput. 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) Quote Link to comment Share on other sites More sharing options...
