[QUOTE="ZaneMasterX, post: 1088772, member: 14823"] "How does the EPA lab work? Vehicles are tested on dynamometers, or dynos, which are like giant treadmills for cars. The vehicle is held stationary while its wheels spin the dyno’s large rollers. After a vehicle is strapped down on a dyno, the staff punches in coefficients that allow the dyno rolls to simulate real-world factors, such as wind and road friction to calculate MPG of each vehicle tested" You know how VW got around emissions and MPG with their diesel vehicles? They had two sets of programming that would run; one that would run when the vehicle was on a dyno and one that would run on the street. How did the car know it was on a dyno? Wheel speed sensors would sense the front wheels werent moving when the rear wheels were which would make the computer use the "dyno software" and not the actual software it uses when all 4 wheeler are spinning on the street. The dyno software was more tame and significantly lowered emissions compared to the actual drive tune the computer used on the street. [/QUOTE]
