Since weight reduction by replacing OEM parts with lighter aftermarket ones is about the most expensive and least effective way I can think of to increase MPGs I would say its a big number.
If you only spend $20 per pound lost you are doing pretty good.

I thought they were easy to tune with that ECU they are using (basically Honda specific megasuirt?) I think it will be very interesting to see what guys who usually tune for power can do for an economy tune. Just kinda wish that they would tests between mods to give the non-informed reader an idea of what makes the most difference. Very cool project though

Being Honda guru's, they are probably going to swap out the ECU in favor of a chipped one that they can custom tune. It is possible to add in lean burn that isn't as picky as the factory tune, so I am curious to see the results. But as mentioned, these guys are not serious about adapting their driving style to improve fuel economy, so any gains from their modifications are going to be dampened by their poor driving skills.

Ohhhhh yea I didn't see they are using hondata. My bad. Very cool project. Im looking forward to the tuning part. They might need to add a 4 wire oxygen sensor in place of the wideband factory one though. The tuning shop in Ohio eliminated the need for 5 wire 02 and egr with their tunes.

"The plan is to lower the car, fit it with aftermarket wheels, custom aero work, full exhaust system, engine work, and finally tune using a Hondata S300 engine management system. What sounds like your average tuner vehicle is anything but typical to a hypermiler. Believe me when I say this build consists of using methods that would shock your average eco driver/car owner."
They will probably run a P28 ecu with their Hondata S300. This will give them full control of VTEC cross over and a fuel map with lean burn light load input values.
They should be able to run a wideband O2 and simulate factory O2 if they want, or just run it in open loop. That's what I did on my Del Sol with Neptune on a socketed P28 ecu.
They should have much better results then stock in FE. The question I wonder is will they be checking for NOx when they push it past the stock lean burn A/F ratio's???
