What am I missing here,I am guessing it's a 02 or cat diagnostics test, It will command 16 to 1 AFR some times makes for a good lean cruse or melt pistion cruse

Sorry this is a late reply (I was going thru my queues picking up anything that had fallen thru )


It not any diagnostic test for NBO2 or Cats...

it looks like Lean Cruise...

( I don't see any LC parameters in your tune file, so I don't know how you would disable it )
