gathermewool Posted September 23, 2009 Share Posted September 23, 2009 Like my gf, there's really nothing wrong with my car, and things seem to be going pretty well for the most part. We get a long well. She turns on when I hit the right buttons and she's never let me down. I've chosen to tune out a few things my gf continually brings up. With the legacy there's only one - P0400! I've heard of people tuning out O2 codes for their high-flow cats or catless setups. I don't know much about tuning, but the EGR system works fine and, instead of spending tons of money trying to fix something that aint broke, I'd like to find a way to get rid of this TDC before emissions are due by mid November...

gathermewool Posted September 23, 2009 Author Share Posted September 23, 2009 FWIW, I used to warm the car up, clear the code with my scangaugeII, and have the system show "ready" for a few start ups before the P0400 code came back. Since I started battling this code, it seems that the problem has worsened as I've remedied certain things like: replacing the EGR tube; cleaning the EGR valve; replacing all of the vacuum tubing; and swapping out the Back Pressure Xducer. The system responds better than ever, but the code now come back before all readiness tests are even complete. There just doesn't seem like any way to skate by the test except for a tuning fix. I refuse to pay hundreds of dollars, and have the problem still not be fixed... '15 FB25 Magnatec 0W-20 + FU filter (70,517 miles) RSB, Fr.

omnicron Posted September 23, 2009 Share Posted September 23, 2009 Either have it deleted in the tune or you might be able to get something that brings the o2 out of the flow of the exhaust. Like a Spark Plug Defouler. I dont know if that works on the Subaru but I know a lot of VW people use it. Link to comment Share on other sites More sharing options...
gathermewool Posted September 23, 2009 Author Share Posted September 23, 2009 Are there any tuners who work on older cars like this? '15 FB25 Magnatec 0W-20 + FU filter (70,517 miles) RSB, Fr. Strut Bar, Tint, STI BBS, LED er'where Link to comment Share on other sites More sharing options...
