The bottom one is engine management - lets you tune the air/fuel ratios, fuel curve, etc. Also lets you display any engine related variables in any format - textually, as analogue guauges, real time graphs, etc. You can set it to monitor up to four things on screen at once, overlaying the graphs, etc.

The top one is the same, but exclusively for the turbo. So it has stuff like boost pressure, speed, etc.

They look way cooler than in those pics, but I dont have a digital camera, so I have to make do with what other people do for me ;) Please excuse the mess the car is in, as well - I hadn't cleaned it in weeks :(
