Fuel Curves and Ignition Timing!
 

Does anyone know the equations for the sock ignition and fuel ingection curves/tables/maps. I am in a math and engineering course and i am doing a project with Fuel to air ratios and ignition timing with diffrent octane fuels. If anyone has info on these subjects please help as internet info is scarce. equations and formulas would be awesome, but i need all the info i can get. :D
