Unfortunately I think there is no real way out. Why are Chinese electronics substandard, because they use substandard components. Where are you going to find better components? Most of them are made in China too. So a USA manufactured unit using Chinese components probably wouldn't be any better. I wish someone had the internal schematic for the Mopar ECU, someone handy with electronics could probably improve on it AND dig up quality components. Remember, even back in '72 everything in them was low bid!
