2004 Subaru WRX
WRB Stage II

Default Cobb AP & TGV Delete tune help!

Car is a 2004 Subaru WRX, Stage II OTS 93 Oct map. Full CATless exhaust and has been on that map over two years.

So last summer I started getting the TGV errors, they disappeared over the winter. Well now this summer I have about all the ones possible, TGV malfunction, right and left stuck open, TGV sensor circuit overpowered, etc etc. I am a machinist and have a full machine shop I work at so I am looking to do a quick TGV delete, powder coat the intake manifold and the TGV's and be done with it.

It is the tune that I need help with. I heard there is a way to tweak the map via the Cobb AP race tuner software available, however I can't find much of a write up on the forums. Can anyone provide a step by step process on how that's done? I don't know much with turning, I don't want to get into it and find I need to learn C++ or some type of more advanced Arduino type programming to fix this. Just need to be able to hide those codes so I can get it out of limp mode and clear the check engine light, I hear the codes stay active on the RAM but not to trigger any issues if the tune is done right.

you can disable them from coming on easily in the map on ATR. I dont THINK you need a retune for that, but do some checking before you take my word for it.

It is at the very bottom in like ETC codes or something like that
