oxygen sensor placent
hey everyone i got a simple question... i have a heated o2 sensor thats located at the end of the y pipe... i have long tube headers custom y pipe and flowmaster 80 series catback... it takes like 2 minutes for it to go into closed loop.... if i move my heated sensor to the driver side collector would it go into closed loop faster or heat up faster... im thinking that maybe i have the sensor too far back... like i said it works it just taking a little too long... i have it hooked to the fuel pump so its only on when the car is running.... thanks in advance...

Possibly, but O2 sensor heat is only one of the variables that the ECM looks at before deciding to go into closed loop. I had a 3rg gen with shorties and a heated O2 mounted close to the collector and it wouldn't go closed loop much faster than yours does, when started from overnight-cold.

Possibly waiting for engine coolant temp to get warm enough before going closed loop.
