8/31/15 EDIT:
Already broke 50% of EPA combined. Turns out that an old cat had left behind a chunk of substrate in the pipe so I had about the exhaust flow of a lawn mower. Pulses are now beneficial and I can hit numbers on open road that I used to need to be drafting a semi to achieve. A crack in my exhaust manifold was leaking, replaced. Now I can go chase other gains. My TDCL cable works now so I can actually record what sensors are doing to a limited degree and figure out how to keep the engine out of enrichment more.
Challenges: My commute has me driving in still air in the morning but the wind picks up by noon and I'm driving into a 10MPH headwind in the evening, the last leg of my morning commute and first leg of my evening commute has me in a parking structure that has aggressive speedbumps.


7/10/15 EDIT: *Ataches electrodes to thread*
*Puts up lightning rod*
*Realizes that I'm in socal so waiting for lightning will take a while*
Screw it. 3... 2... 1... CLEAR!
*Necros thread*
Change of objective: I'm an engineering major now and being able to say as a project I applied, tested, and evaluated modifications with an ultimate result of a 50% increase in fuel economy over my baseline fuel economy should look at least somewhat interesting to employers looking for an intern.
I'm getting around to installing the MPGunio.
Currently done:
Base timing is increased from 10 degrees BTDC to ~13 degrees BTDC, the max timing that will pass the inspection component of a california smog test.
WAI (only used when temperatures are low enough to allow).
Upper Grill block (only used when temperatures are low enough to allow).
Air dam.
Better tires (Michelin Defenders, 185/70/R14)
NGK spark plugs (seems that the 4A-FE loves ngk and denso spark plugs)
10W-30 Mobil1 Extended performance synthetic oil.
AMSOIL MTG 75W-90 GL4 synthetic oil in gearbox.
Phillips Xtreme Vision low beams (smaller and hotter filimant means that they put more light out the front and don't dim to the point of uselessness when in EOC).
LED interior light. Old draw was 1 amp, new draw is .1 amp (I used 2 LED sign backlight modules at .05 amp each, I could use 1 if my dome light's plastic wasn't opaque from age).
In the works: Rear wheel skirts
Smooth hubcaps if I can find suitable material
New front motor and front exhaust mounts to make drive more doable.
TO TEST: Determine conditions ECU goes into enrichment and have an indicator for when it goes into that.
Determine cooling requirements for car on highway.
Determine fuel cutoff behavior.
Calculate current cd and frontal Area.

END EDIT

I want to try to keep my car efficient even when doing 70mph-75mph (or according to my speedometer: 65-69 MPH) on the freeways. Since most of the energy will be expended to move through the air, I'm going after aerodynamic losses first.
I'm thinking an air dam and side skirts as a starting point, maybe something on the front wheel well.
Target MPG at 70 MPH is 40 MPG.
I am contemplating figuring out a way to have an swamp cooler setup so that I can cool the cabin when the air is 100F outside (at 20% humidity,) without compromising FE.
