Introduction with Questions

Hello, my name is Adam Brown and I am a senior in high school, so this should give you an idea of my financial situation. If not, I have about 200 dollars to my name or not enough money to get any hardware to pursue full out tuning yet. However, my senior project is all about PCMs and I am attempting to construct a flowchart for a simulated efi system to improve fuel economy, because it is the most school appropriate modification. I have to skeleton of the flowchart done, meaning you press a button to simulate throttle, there is a period of idle, another section to simulate deceleration, and a shut off command when the button is not pressed. I need details now including a specific car, preferably american brand, to get real numbers in terms of AFR per RPM and what not. I self taught myself and have been learning since late January.

All help is much appreciated.
