We have it pretty easy now for diagnosing Engine Management problems. AMC on the other hand decided to make it hard, then release this handy tool to solve it. Lets go through the AMC/OTC collaborative effort that was the ET-501 Fuel Feedback System Tester, what comes in the kit and how it all works.
I have scanned and uploaded the manual for the tool to the Internet Archive. you can find it here: archive.org/de...
The 4 and 6 cylinder diagnostic ROMs have also been dumped and uploaded to the same place: archive.org/de...
(When burning them to now EPROMs, be aware of pin orientation!)
About ten minutes into the video I mention the later Bendix and Renix computers used in Jeep/Renault vehicles at the time for fuel injection. Neither do I own vehicles that use those systems or the diagnostic tools that were available for those near the end of AMC's life but I have been given access to training laserdiscs which discuss it and the MS 1700 diagnostic tool. You can find that here: archive.org/de...
