Carmen is an aspiring Jekyl-and-Hyde. She's a sports car, and she knows how to drink like one. I'm often quite economically-minded. My goal, therefore, is to get her to achieve significantly improved fuel economy upon request, without having to permanently sacrifice an ounce of performance.
Near-term: Custom-tuned ECU
Long term: Carputer capable of modifying ECU programming on the fly and performing all scangauge functions; aero mods (underbody pan, etc.)
