I know about a thimble-full in this regard but I can tell you that there are "speed density" and "mass air flow" systems (Ford makes both) and the MAF type is easier to install and tune. The "speed density" types are not as adaptable for use in other than its stock form. MAF is upgradeable. I think this also relates to the number of sensors needed.
Here's the gist of it as I know it. You need to graft fittings onto your exhaust system for oxygen sensors. The piece needed is sold by Windsor-Fox Engineering. The computer and MAF sensor come from the donor car as well as the upper and lower manifolds and injector hardware. A conversion harness is sold by Windsor-Fox to make life easier when hooking up components.
Fuel line has to be supply and return, so a return line has to be added. The usual way is to buy a fuel tank sensor fitted with both output and return line fittings. This saves you from having to modify the tank itself. An electric fuel pump is used. Your mechanical fuel pump is removed and blocked off.
The accelerator linkage has to be modified to cable operation from the current bell-crank affair.
The best deal is to hook up with a company specializing in doing this conversion such as Windsor-Fox. It may be a bit more expensive but its better than learning the hard way.
