"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???
