The electronic FI developed by Chrysler in the 50's was not all that great and had a lot of reliability issues. Those that bought a car with it in it typically had the FI removed and replaced with the typical carb set up. The next production electronic FI system produced by an american car company was used on the Cosworth Vega in 1975 and 1976. I think it may also have been used on the Toronado. Bendix and GM jointly developed the electronic FI for the Cosworth Vega.
