D-Jet or L-Jet, Which is best & why? Options

[windforfun]

Which FI system is best & why? I just watched George's video (most of it) & now I'm curious.

Word. Clipped rom Wikipedia:

The first commercial electronicially controlled manifold injection system was the Electrojector developed by Bendix and was offered by American Motors Corporation (AMC) in 1957.[34][35] Initial problems with the Electrojector meant only pre-production cars had it installed so very few cars were sold[36] and none were made available to the public.[37] The EFI system in the Rambler worked well in warm weather, but was difficult to start in cooler temperatures.[38]

Chrysler offered Electrojector on the 1958 Chrysler 300D, DeSoto Adventurer, Dodge D-500, and Plymouth Fury, arguably the first series-production cars equipped with an EFI system.[39] The Electrojector patents were subsequently sold to Bosch, who developed the Electrojector into the Bosch D-Jetronic. The D in D-Jetronic stands for Druckfühlergesteuert, German for "pressure-sensor controlled"). The D-Jetronic was first used on the VW 1600TL/E in 1967. This was a speed/density system, using engine speed and intake manifold air density to calculate "air mass" flow rate and thus fuel requirements.

Bosch superseded the D-Jetronic system with the K-Jetronic and L-Jetronic systems for 1974, though some cars (such as the Volvo 164) continued using D-Jetronic for the following several years. The L-Jetronic uses a mechanical airflow meter (L for Luft, German for "air") that produces a signal that is proportional to volume flow rate. This approach required additional sensors to measure the atmospheric pressure and temperature, to calculate mass flow rate. L-Jetronic was widely adopted on European cars of that period, and a few Japanese models a short time later.

wow. amc. never knew that. they were an interesting company weren't they.

i'd have to bone up on it all again, but think i remember that america did all the heavy lifting work on the development of the transistor?

important to remember germany had a context for being enthusiast about fuel injection, admittedly high pressure style mechanical injection - from WW2 on. perhaps reason for bosch grabbing the bendix tech. its all a bit of an german/american partnership post WW2 too. space program etc. the best of both worlds.

wasn't the bosch proto D installed on a mercedes as a bosch skunk works project?
but merc hesitated so they drove down the road to VW who jumped straight in.
