And you'd have to develop a "safe" map for each model you support...)
Some newer cars already come with such maps for their "Eco modes", and they include dialled back timing, dulled throttle response and altered transmission algorithms.

That's the advantage of a flash tuner though you can still switch between a number of different tunes including a stock tune. You could even use a custom flash tuner in place of a scangauge or ultragauge. I wouldn't necessarily try to sell this I really would like to try to makes this something you can build yourself like the MPGuino. Also I get that even for those who have a manual transmission this isn't as helpful either but for someone with a automatic adjusting those parameters can improve gas mileage quite a bit.
This would be pretty similar to the "Eco modes" in new cars if you look at my original post I talked about that. I was just wondering if anyone has experimented with tuning a car for gas mileage only.
