    Default o2 sensor bypass

    Hey guys,

    first off 2000, GMC Yukon XL K2500 4x4 6.0L

    I Wanted to know if anyone knows of whre I can get someone to reprogram my pcm to ignore my rear o2 sensors so I could remove my cats. I know is most places emissions are a problem, but where I live we have no emissions regulations.

    Thanks

    2000 K2500 Yukon XL 6.0L Vortec 252000KMS custom CAI, and exhaust...but not done yet.

    This is a good question for Jenna Bear. I know it's illegal to do this but I'm wondering if it can be done.

    it may be illegal where you are... but here it isn't... we don't have emissions testing, and there is no law saying we can't do it.. at all... just noise violations.

    Cool O2 sensor bypass

    Diablo Preditor # U7198 will let you turn off the codes for the rear O2s. They dont advertise this on there website but every gas GM truck 2000 and later that Ive installed diablos in have this. It just keeps the codes from lighting up on the dash. You have to keep the rear O2s plugged in per Diablos recommendation. Diablo has a gas truck forum that answers alot of ???s people have on tuning.

    thanks for the advice, I was hoping though I could get away with something that wouldn't require me to buy a programmer per say. If I was to buy something it would probably not be a handheld but a LAPTOP hookup.
