Will read-up on the procedure, thanks Charlie. I guess changing the AFR sensor screws it up to this degree... As I recall with my SC2, on my MINI Cooper S, I was able to tweak or fudge some settings like vehicle weight, displacement, something else, such that on fill-ups, adjustments were really not needed. It took some playing, but I was able to get it very close to where it became set it and forget it... Hoping to refine the UG to the 4Runner like that, at some point.
