If that weren't so, Toyota would run the motor at that AFR too, and so would everyone else.

Toyota does. Stock the cars (Toyota's in general) can run as high as 17:1 AFR while at cruise.

i dont know where you got you information... but 14.5-15.2 seems to be the norm at cruise. and thats the closed loop setting unless you start tuning that.

at 17 there is a severe loss of power. when we had the bogging issue thats where it was, then the ecu would dump fuel and suddenly it had a ton of power.
