Fuel injection

anybody know anything about http://www.mass-floefi.com/, i know it uses a ford ecu and sensors with a gm style mass air meter. i have played around in the past with fords wiring (i put a fuel injected 4.0 where a 2.9 carb was), actually did this swap a few times and know that the wiring is not hard to deal with. also like the mass air aspect, but beyond that????
Have on my motor and have no complaints yet.
