question: has anyone tried welding in a second bung in an aftermarket downpipe to accomodate both o2 sensors? basically, let the real o2 sensor do its thing so the computer doesn't complain... this way you don't have to touch the wiring... in theory the computer could be checking that the second o2 reads leaner (thereby verifying that the cat is actually working) but the o2 simulators seem to just randomly oscillate, so the ECU must not check this too carefully...
