  1. How did you run an Emissions Diagnostic in the 80's?

    In my last article I discussed AMC's CeC fuel feedback and emissions control system and specifically how to depot it for the purpose of reverse engineering. This consisted of one Intel MCS-48 microcontroller and a dozen inputs and outputs. This was pretty normal for the time and other automotive manufacturers were using similar designs, if not borrowing from one another. The problem with going this route however was that the system was closed-minded. There was no OBD2 and there was also no OBD1. ...
  2. Depotting an 80's MCU from Ford...for AMC

    Mention fuel and emissions control to people who lived through the 70's and early 80's with a car and for some reason the music of CCR and the sound of helicopters start going through their heads as if the Malaise Era was as traumatic to them as Vietnam might of been.
    Basically in that period the ability to run an engine loud and rich was being clamped down on to deal with smog and fuel shortages. Initially it was devices such as anemic carburetors, smog pumps, the Exhaust Gas Recirculation ...
