N2 Fuel Use

Hi, What does N2 use to figure fuel use....engine rpm, speed of veh, distance gone by veh...or what. Or is it more complicated? The reason I ask is....say on yellow laps, if I use third gear vice second gear will I save fuel. Thanks, Jim

It's a function of engine RPM and throttle position. More RPM, more fuel; more loud pedal, more fuel. Yes you will. (But you don't use much fuel under caution anyway...) ---Jim Sokoloff, Papyrus

All these factors apply. If you look at your F3 screen (fuel mileage) while under caution, change gears and look at the mileage. I usually run in second gear at the short tracks, and third at the superspeedways. Yes, it does save fuel in a higher gear. Jimmy

>The reason I ask is....say on yellow laps, if I use third gear vice second >gear will I save fuel. I run cautions in 4th for that reason. Okay, so it hasn't won me a race yet :), but it *does* save fuel, at least by my accounting :) See ya... Cat
