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.

I've got a friend that's had his 63 Vette with the old Rochester injection system since 1965. He gets fuel economy in the mid-20's even with that old system.
We are getting way off topic, but it's fun stuff.
First, collor me green. I always wanted a FI vette. I owned two vetts, a 59 with a 350hp 327 and the what I though was a 62 but turned out to be a 61 trickeed out. I never got that one restored.
In the 60's, the there was an intersting thing going on. The cars they were advertising as their economy cars were getting way less gas milage than the muscel cars. I had a 61 Pontaic Catalina with the 348 HP tri power, four on the floor, 390 positraction, etc. My first "new" car. Cost me $2900.00 and a 47 Plymouth coupe for trade. That car would get near 18 mpg even the way I drove it at 19 years old. The same car with the Econnomy package was hard press to get 12 MPG. But at $0.25 a gallon, who cared, that was only 6 minutes pay.

My cousin had a black 59 Vette. He's never been without a Vette since.
And a guy down the street from me had a 66 Dodge/Hemi 4-speed 6 MPG [:@] in good weeks.
