If anyone's interested, I've taken all this a bit further now. In my final year (which started this Monday) I have to do a project, and I have decided to use a 1.6 Fiesta Zetec S engine we have, a MoTeC ECU we have and finish building a Megasquirt ECU we have, and play with setting the engine up with each system, possibly with the OEM Ford management too. I'll make comparisons between the systems, as well as fully researching engine management systems and mapping. I'll be working with a lecturer of mine who's had many years' experience with mapping and setting up engines, including re-mapping OEM ECU's. I'll be using the university's dyno, and basically spending as much time as possible playing with everything I can and getting a feel for it all with an expert by my side
