..just a minute, I had to get my soapbox.

Ok,... Now...., if High Pressure Fuel Injection had been adopted soon after it was perfected 60 years ago, we would have been able to double our fleet ave. MPG and have clean air to boot (i.e. never needed cat. convertors).

Oh, yeah, another thing we would have never needed, . . foriegn oil.

Think about that, and 'round up the culprits while your at it, I'll get the rope.

Fuel injection was perfected with the introduction of the ECM onboard computer; all earlier models were big flops for all around driving.

I used a Hilborn fuel injection system in the 70's in one of my Drag cars.

It basically had two positions, wide open and idle.

Part throttle operation was impossible until the advent of speed density and now mass air systems and the required computer power to run them.

Modern versions use a feedback loop with a O2 sensor that maintains a air/fuel ratio based on several factors including throttle position, distributor advance, temperature and the software in the controller itself.

Fuel Injection was ahead of its time.  It needed the power of computers to make it practical.
