I'm a gearhead/engineer/inventor who's passionate about energy efficiency and renewable energy. Glad I found this forum! So far most of my mpg efficiency work has been planning (mileage improvements for my 1987 Grand National and 1979 Cutlass). I did, however, almost beat the EPA HWY estimate in the city while driving my 1994 Subaru Legacy Wagon. . .I got 25.9 on a car rated at 21 city. Since my understanding of the OBDI Subaru ECM is that it does not engine brake by shutting the fuel off, I did a lot of coasting in neutral. If I could install an injector cutoff switch I imagine I could do even better than the 25.9. . .
Anybody know how to put my car/mpg info in my profile?
