Thanks I understand what you are saying..I was just wondering if the pcm would accept the (split) sensor value or would the value change (resistance wise) since it is being split and sent in two different locations? Not sure from reading the tuner forum posts but it appears that some tuner folks are removing OEM exhaust manifolds with two upstream O2 sensors and installing headers with only one O2 sensor...I was just trying to understand if it's possible. Guess this is more of an electrical question. Thanks again.
