You guys need to listen to tool pants. The second sensor is there to determine cat efficiency. If you run the OBDII program in the ECU you need at least 2 cats and 4 O2 sensors or somehow do a band-aid solution into tricking the ECU into thinking that the cat is there by using a false signal for the after cat sensor. The same can be accomplished by running an ROW ECU program as these cars only use a pre-cat sensor for mixture determination and don't have an after cat sensor for Cat efficiency.
