I have a 2011 wrx sedan with a ton of bolt ons. turboXS fmic/CAI, turboXS turbo back catted exhaust, perrin inlet, grimmspeed ebcs, GReddy type S BOV recirculated, DW65C fuel pump and I believe the rest is irrelevant. Basically a decent stage 2 setup.
I am running TP stage 3 e tune and I cant say enough about eric. However, I have had a knock or false knock issue for over a year that I can not get to the bottom of. Basically the car pulls timing and learns to pull timing at WOT under full boost. It ranges from 1* to 4+. I cant find any apparent mechanical issues and I don't hear it knocking when the issue occurs.
I'm very sick of this car and about to trade it in if I cant fix the problem. I don't believe there is a boost leak but I could be wrong. Someone who is avid in tuning and is familiar with these cars please point me in the right direction. No CELs, not over boosting or under boosting, no smoke from tailpipes, no smoke or puffing from oil filler cap. I'm baffled at this point.
today 3rd gear pull
a couple days ago again 3rd gear
this ones clean.....
this one is not bad either....
this is the worst one yet....
actually this is the worst one.....
ok......so that is just a little bit of the history of the logs......since that terrible one a revision has been made and I fear it is heading back down the same direction. Any insight would be great.
