This paper describes a computer-controlled engine test cell being developed at the General Motors Research Laboratories. The object is to combine the advantages of the controlled experimental ...

During their final years, a handful of automakers experimented with computer control of the humble carb, trying to squeeze out every last bit of efficiency and reduce pollution as much as possible.

An illuminated “check engine” light tells you that the engine control computer has detected a problem that may be causing the vehicle to produce excessive emissions.

Because many engine-control computers freak out when not connected to the factory instrument cluster, I saved this one.
