here is an on-line version of one the projects I work on for my job. I spend about 15 to 20 % on my time on this project. The engineers I do work for are the 3 controls guys in the white lab coats, these guys are very smart (PHD's) when it comes to engine controls. I did some of the mechnical/ Fab work and some running of the dyno.

this is from popular mechanics magazine.
