Ah. No. ECU's are made up of many chips from many different manufacturers from many factories.

If you are refering to the Microprocessor chip, the main chip, you are still wrong. As far as reliabililty goes, my Buck Lucrene runs great, many trouble free miles, cheap to fix and every mechanic can work on a Buick. I wish the Toyota MiniVan ran as well as the Buick does. Don't even get me started on the modern Volvos.....................
