    Ok, and then i can remove the EGT sensor and wire from the up-pipe and just plug it with a bolt correct?

    Gentlemen, did the mod yesterday, reset the ECU, CEL came back on last night. Ill check the codes later tonight but I have the PnP grimspeed headers, up pipe and invidia dp- All catless. So I guess that its the 2nd O2 sensor. The link for the do-dad you splice in is dead and I was hoping someone knew how to do that mod with radioshack gear

    Has the Computer been tuned for the catless downpipe? If no, then that's your problem. Please read the stickies (FAQ's) in this portion of the forum

    Specifically this one.
    Yes, you need an EM for engine mods

    Ahthankyoo.
    had a friend read out the code, forgot the # but it was bank 1 cat inefficient . untill i save up for the larger turbo, intake, tgv's and PnP intake manifold to justify the tune..... i guess ill just look at the light

    I just bought a 2002 Subaru WRX a few days ago and it has a full Cobb exhaust, I've been getting P0546 The EGT Sensor (Bank 1), it says circuit high. I also have a gauge in the car that should be reading that sensor while I drive but its been pulled out and bunged up, so unless there's another sensor I'm not aware of, I'm not sure why I'm getting this code...

    I had a similar problem getting EGT codes when installed full decatted uppipe + downpipe + catback. As upipe was catless I decided to remove EGT sensor to avoid damage to it. Just used Tactrix Openport cable and Ecuflash to disable all EGT sensor related codes.

    I just found that my uppipe is aftermarket and the EGT sensor is still plugged in so I think I'll try to do the resistor mod and see what happens.
