I'm trying to use my MPVI3 to disable the post o2 tests on my offroad truck but I can't seem to find the option anywhere. It's causing my wide band to swing when letting off the throttle. Am I looking for the wrong label or has this option been removed?
Sure you're not referring to DFCO? Decel fuel cut? Normal for the wideband to read full lean as it's just pumping air through the motor.

Option removed. You'll need v4.8 or user defined parameters with a defined xdf file. Like what Greg is saying, looks like the entry to DFCO. It might be that it's kicking itself out of DFCO straightaway then going back in. You can log all that if you're not already.
I'll run a log today, but looking at the tune I have the DFCO Cylair Enable/Disable tables modified. I'm assuming this is causing the rapid swings I'm seeing off throttle. I put this together so long ago that I don't rememeber why.
