Here's a better look for our tech heads :nerd:
Notice that no matter the situation, the afr never goes below 12.08 or above 18.12. Not one bit. That's why I think the that is just the limits of what the sensors and/or ecu can "measure" and the actual afr at WOT is actually quite a bit lower. It has to be. Even if the 12.08 is the somehow lowest afr the car could achieve despite the targets, no way it would hold a steady 12.08:1 ratio throughout the entire rpm range.
As far as my ocd is concerned, as long as the numbers are accurate between 12.08 and 18.12, its ok. I obviously want to keep well within that range anyway. Hopefully,
my next tune leans the car up a bit.
