a lot of things tuners do to make their car faster can also apply to ecomodding (ie aero parts).

Apparently, the stock tune from Subaru runs a bit on the rich side. Cobb Tuning makes a thing called "accessport" that allows me to change the ecu tuning on the fly. People say the basic off the shelf Cobb tune, they gain 40hp right off the bat plus an extra 3mpg without altering driving style(and these are people that already drive the car aggressively). I imagine i can squeeze more than 3mpg with that kind of tool

However, it costs $650...with the amount of miles i drive everyday, the payback period would be 15,000miles depending on how long i keep the car, it may or may not be worth it.

See the rest of the Sti project log:
