Fuel injection is a timed event for a reciprocating engine. The ignition is still always there, but the fuel charge can be made more precise with the injection than with a carb. Same reason that a 350 chevy gets better fuel economy with fuel injection than it did with a Rochester Carb.

Bill, This is very true. I've got an old 1991 Lexus with a big FI V8. I'll bet it would turn the 1/4 in around 15seconds. Not bad for a 4 door sedan. The thing gets 26mpg on the highway and around 23 in town and I don't baby it. Quite a difference From the rochester Carb days, or even from the early Vett FI days.
