Officially "off road" of course, removed cats, O2 sim.

Say you wanted to maximize miles per gallon up to WOT.

Lean burn, Minimal idle, tight shifts, up and downshifts based on efficiency, not smoothness.
Mid speed (55MPH) throttle settings presumed to be between closed and 50%, 3/4 throttle still economized, but rich enough for no stumble, transitino from 3/4 to WOT as stock, WOT set for maximum power (HP/TQ).

Durability and reliability should be withing realistic limits (no melted pistons when completed) Drivability allowed to suffer at less that 75% throttle for economy.

0 to 50% throttle absolute maxed for economy, without destroying engine/systems, and without requiring excessive or permenant modifications. Should still meet MVSS accereration minimums for safety

Presumed to have free flowing intake, OEM engine/exhaust manifolds, possibly catback or custom duals, street legal sound, narrowband O2's or WBO2, but no "live" tuning - (No OBD2 port connection permitted)

Duration of run to be in weeks, and thousands of kilometers; not single 24/7 contest, but average over many runs.

Vehicles (for competitiveness) will feature OEM automatic tranny, but low resistance tyres, and external aero mods, lightened and stiffened chassis body..

Altitudes are sea level to 1000 meters, grades to be as high as 10% so engine braking WOT are needed. Handling to be low speed sharp turns, moderate speed turns - typical modern road coarse of gentle off road course - not oval or test track, nor straight line.

What would YOU do with EFILive to accomplish this??? How would you validate it
What minor mods would you perform?

Also vehicles may be returned to OEM conditions afterwards so permanent mods not permitted.
