Help with HP tuner (First timer)
Hi, a question for HP Tuner users. I have a failure code of low voltage on the rear O2 sensors after completing my exhaust conversion to Speed engineering headers/3 inch pipes, with new SS cats between the headers and x-pipe. In HP tuners do I just turn off the low voltage sensor 2 boxes, or do I turn off everything associated with sensor 2?? I turned off just the low voltage boxes and I've driven a hundred miles or so and I'm not sure the ECM has reset. I'm going to try to do a VCM scanned today to see what that tells me, but as any HP tuner user knows the Suite is very complex with so much stuff that a new user like myself is totally intimidated and finds a huge learning curve ahead of him. I just need to have the computer not reporting failure codes like low voltage on the O2's if I plan to get through the emissions station. Thanks!

Thanks for the reply. Some of it makes sense but it's a little different than what I'm seeing. I have the latest MPVI 2 which might account for the differences. All I've worked with so far is the DTC list. I'll have to go see if I can find the Cat and post o2 tests. All I really care about at the moment is the DTC's not going off.
