Came across commanded lambda and EQ showing backwards in the scanner.

2016 Mustang GT, FSGP1A2 OS.


Lambda target of ~0.835 at WOT (1.19 EQ), commanded lambda shows ~1.11, commanded EQ shows 0.9. Fuel trims ~-7%.


If you go off the commanded vs desired, it would lead you to believe you're way out in left field, even though the trims show 7%. If you swap lambda and eq labels you'd have 1.11 commanded EQ with 1.19 desired, so ~-7% error. Or 0.9 commanded and 0.835 desired, ~-7% error.
