okay, sicne the k-pro apparently is running off of the wideband upstream O2 sensor....if i take the cat off, do i need to weld a bung into the replacement piping...or just not need the downstream O2 all together? My main concern is power distribution by not having the extra O2 sensor causing damage to the ELD. i basically do not want the computer freaking out if i dont have the downstream sensor, i guess is what im trying to say.

 

Get a second O2 bung for the wideband
