Default Any CELs yet with new exhaust?

The WRX is a CEL happy fool. I know the TurboXS guys are CEL free with their STi, and Dan at Godspeed has no CEL either. Any of you everday consumers experiencing CELs after changing most of or all of the turbo-back?

Yes, I got a Cat inefficiency CEL when I mounted my ScoobySport Turbo Back.

I studied the ECU wiring differences between the WRX and STi and moved my ScoobySport CEL eliminator over. No more CELs.

Is there a wiring difference?

Yes:
Instead of the Yellow/Blue wire on plug 137/Pin 3, it's on Plug B135/Pin 6. Often called Plug 'B' in the manual.

The White wire is not plug 135/Pin 17... it's Plug B137/Pin 25. This is often called Plug 'D' in the manual.

Hope this helps,
Russ

Here are some hopefully clear instructions...

The wire colors are the same, they're just in different positions on different plugs. Below is a diagram of the plugs with the wire locations circled.

Just connect the wires as described in the ScoobySport CEL Fix instructions, but use the wires in the below locations.

So far, no more CELs after this fix.

Unhappy Is MIL eliminator needed with TXS HE cat

I'm confused. I put on a TXS exhaust from the turbo on back with a TXS cat pipe and muffler. This is on my STi. I had help from a WRX enthusiast. We used a MIL eliminator. I got CEL. Dealer charged me to tell me that it was an O2 code. I could live with it but from what I am reading I should not have to if I am willing to invest a little more time and money. But I'm confused as to whether or not we should have use the MIL eliminator at all. My friend said it was made for '03 WRX and the Sti is obviously reading the sensor differently. But I am not catless so why did we put one on at all. Is it needed for the high efficency cat. I am thinking of removing the MIL eliminator and resetting. Any thoughts from someone more familiar with this issue. Thanks.

The resistor that WRX enthusiast have always used on the WRX to free themselves of the CEL will not work on 04 and up impreza models. This is because as you mentioned the 04 reads the sensor differently.

There is a fix in the works, companies like Perrin are hard at work on plug and play 02 sims that will make the lights go away. In the mean time your only real option is to do something custom like those who have posted previously in this thread.

BTW, I have a catless TXS and have been CEL free for more than a month. This just goes to show you that the CEL is finikey at best.

CHeers,

CHeers,
So do you also think removing the MIL elim. from my catted system might stop the CEL? If it is the wrong one could it not cause the CEL?
