[QUOTE="006, post: 13151063, member: 5015"] Hmm, why do your graphs above show your bank 1 upstream O2 sensor flatlining? This would indicate that it's not switching as it should. Here is a datalog of mine from these threads: [url]http://www.svtperformance.com/forums/new-edge-cobras-51/936712-asking-some-return-help.html[/url] [url]http://www.svtperformance.com/forums/tuning-la-carte-375/937117-help-datalog-reading.html[/url] Lazy O2 in pink [img]http://imageshack.us/a/img259/6892/datalogvscreen.jpg[/img] [img]http://imageshack.us/a/img254/9472/logvt.jpg[/img] Replacement/new O2 in pink: [img]http://imageshack.us/a/img607/1130/logviupstreamnewsensors.jpg[/img] Rear O2's switching normally: [img]http://imageshack.us/a/img339/4050/logvdownstreamo2s.jpg[/img] You can see that my two issues were the EGR (flatlining) and the bad/lazy O2 sensor on bank 2 (slow waves/not switching at the same rate as the other side).
