Yeah, that's the problem (at least as I understand it): the SGII isn't actually measuring fuel consumption directly, it's inferring it from other measurements and some assumptions, like the A/F ratio. If your engine doesn't follow the assumptions it uses, the values will be wrong.

There are other cars besides the Insight that have some variety of lean burn tech: Lean burn - Wikipedia, the free encyclopedia
