Chrysler's system was the first EFI, yes. It was attempted at a time when electronic technology was not advanced enough to make a successfully reliable EFI, as it was much more complicated than mechanical fuel injection. While Chevy's mechanical fuel injection system, introduced a year earlier, did have problems too, and many owners swapped them out for carbs, thousands of units over 9 years of production is a lot more successful than 35 defective units recalled at launch with the abandonment of the program for over a decade. This is what fratzog lover was getting at when he said, "Rochester had Chrysler beat at fuel injection back in the day." They did. He wasn't claiming that they were the first EFI.
