Bosch wrote the book on electronic fuel injections for the world to follow. Some of these systems are 20 years old!I noticed on the newer Japanese and American vehicles,any critical fuel and ignition components (injectors,map sensors,hall sensors etc),the grounds are run back to the inside of vehicle.European manufacturers were notorious for grounding all circuits directly to the body or the motor, where they are exposed to the elements(cheap?)Would future problems with critical electrics be rectified if the grounds were taken out of the engine compartment ,and ran to the inside of passenger compartment where its clean and dry?Can the computer be destroyed by resistance in the grounds, to the various sensors?Any computer electrical engineers out there?Just a thought.James
