Welcome to EM! Hondata does offer some fuel saving chip tuning, and the more recent Civic ECUs apparently make it easier... 2005 and forward apparently the Hondas' ECUs practically invite tuning. Hondata does tuning for the 2005-present Civic HX models, IIRC what I saw on their site. You have to mail them the ECU, I think. Don't know if you have a Honda. But it is true that nearly all of Hondata's interest and business appears to be for more HP not more MPG.
See my car's mod & maintenance thread and my electric bicycle's thread for ongoing projects. I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
