Electronics has always baffled me, basically because I know nothing about it, but then when I decided to give it a go I found that it wasn't to difficult, as long as you take the time to read up spec sheets, instructions and so on.
FI is pretty much the same. If you can tell the difference bewteen rich and lean, and know how an engine works and it's requirements then there will be a way of compensating for it.
Start simple, like rpm and TP only, with an option for cold engine enrichment and this should get you going. Then add extra parameters as you get more familiar with how it works.
Be prepared with some spare top end though
