Hi Ben
1: a ford ecu
yes - a generic family of ecu fitted to virtually the entire ford range from the mid 80s up to late 90s
2: ability to control an entire engine from fuelling to ignition.
Absolutely, and more
3: can it handle forced indution?
Yes, with mods and a pressure sensor
4: most famous use (i.e modle of car)
as said, all ford cars apart from cossies - the development work by cosworth demanded an ecu cosworth were familiar with
5:anything else interesting.....is it difficult to program? do you make your own software?
this is the fun part, yes, you would need your own programming softwarea lthough some commercial packages are available. If you have a good knowledge of microcontrollers and electronics the unit can be made fully programmable - I have all the details, the pdf file on my site will explan most of it, I also have some software simulators, dissasemblers, readers etc, for this ecu.
