Acceleration mini-experiment

[caprice]

Remember in high school physics class, there is a measurment for the rate of acceleration? Miles per hour squared, i think.

Heck with the physic caluclations I used to do in school, and a scanguage, you could do graphs of MPG vs Trottle position vs RPM. Then M/H^2 vs Fuel.

Also you could do a quarter mile fuel usage testing... instead of measuring speed, you measure fuel consumption. At the "traps" be going 45 MPH every time. Test from (WOT to 45mph then cruise) to (take the whole quarter mile to accelerate to 45 MPH.) Graph it.

Just wanted to throw some idea out there. My manual transsion car is out of commision this week, I'm fixing a power steering leak. And I don't have a scanguage yet.

Mmm-hmm. I think that this is the key. Accelerating as quickly as you can w/o making the ECU put you in open-loop or in a richened state.

Ya, that would be perrrrfect.
