Hi,
After about a year of utilizing the arduino forum I have finally made an account. During this time, mainly summer 2013 I have been working on a project iEFI, it started out as a pretty straight forward electronic fuel injection program for my Mega and my DUE. Over the course of developing this project I have made my simple fueling algorithm quite complex. It compensates for: absolute pressure, engine speed, engine acceleration, intake temp, coolant temp, voltage, volumetric efficiency, exhaust oxygen content, and throttle position. Before I left for school this fall I was working on rigging up my briggs & stratton to be my test mule. I am hoping to continue with my project in a couple weeks when I am on winter break. If anybody is interested in looking at my code, or would like to help out and take part just let me know! The engine currently has, IAT (intake air temp), a encoder wheel (36-1), a MAP (manifold absolute pressure) hook up, and EGO (exhaust Gas Oxygen). I plan on running the engine carbureted with the ECM installed at first to data log the engines carb'd runtime characteristics.

Thanks!
