I love the FI, but I think this claim was "just a bit overstated." Our system 
does sense temp and air pressure, but there's no feedback mechanism to tell it 
how it's doing. That only came with the much later systems which have the 
Lambda sensors, which sense oxygen levels in the exhaust and feed this 
information back to the FI system. Such a system is called a "closed loop" 
system, but ours is an "open loop" where there's no feedback path.
