Definitely in agreement here, and was going to richen the entire map when the weather warmed up.

I always thought low 15 was safe because in closed loop the mixture would generally run on the leaner side of stoich, and go as lean as 15.4ish frequently. I probably should just be playing it safe rather than trying to squeeze out as much fuel economy as possible...

This is what I was saying about the difference between the Yaris ECU and the Echo ECU. The Echo's is way more forgiving if it doesn't see normal values. The Yaris will freak out and correct them.
