If the throttle position is precisely 20% at six o'clock on Thursday cruising on the freeway, and it's also precisely 20% at seven o'clock accelerating out of a stoplight, is the same amount of fuel being used (gal/hour) in both instances? If you are idling in neutral, would throttle position be 0% or would it reflect fuel usage? Is fuel usage linear from throttle position 0% (none) to throttle position 100% (maximum possible fuel injection)? I am asking in reference to the OBD-II parameter ID 01 11 (
OBD-II PIDs - Wikipedia, the free encyclopedia). If you have a glimmer of an idea, please reply!
