I have a Bassani x-pipe with cat deletes (off-road), is there a setting I can use in the U7140 to satisfy the o2 sensors and safely use this pipe or do I need a custom tune?

Thanks!!!

Anyone? I have seen in several other threads that the techs are pretty sure the rear o2's are turned off, is this all that is needed though?

thx

The rear O2s are disabled in the tunes.

Thanks

If you disable the rear o2 sensors in the tune be sure to remove them completely from the vehicle prior to disabling them as I have heard that leaving them in unplugged and un powered ruins them.
Better to remove them completely and fill the hole with a old style chevy spark plug.
It may not seem like that big a deal but those sensors run anywhere from $80 to $130 each and no sense destroying them when when a less restrictive alternative is to replace with a spark plug.
