1983 D.C. Johnson FAC-1 Revision C

This is a 1983 D.C. Johnson FAC-1 Revision C. It works like new with just few minor repairs. That’s 30 years in service and now ready for many more. Not bad!

The D.C. Johnson FAC-1 is an Air/Fuel control unit similar in function to the OEM “Lambda Controller” units for European cars equipped with mechanical fuel injection systems. It was designed to retrofit cars made for sale in the European market before emissions regulations were instituted, to meet United States specifications after they were imported into the United States of America.
