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????

Depends on what you're doing with it. Their system only applies to V8s (I saw a similar post on slantsix.org, so I wanted to check what you're up to) because they're using a 5.0 Mustang ECU. They generally fire up and run out of the box, but you're not going to get a canned tune that will get you as good performance as a tune set up for your engine, whether you go with a speed density or mass air flow ECU.

Their MAF is a bit of an interesting one - it's not a recycled GM part, and they've done a pretty clever job at packaging it. I've also got to give them credit for the shear variety of port intakes they offer.
